Paint maintenance, choose waxing, sealing glaze or coating it?

We chatted about the car's paint care, waxing, sealing glaze, coating, etc. These now common paint can tell some beauty items. But exactly what is the difference between them? What are the advantages and disadvantages? Many owners in the selection must also be confused. I will introduce today.
    distinction between product composition and role of
    Waxing: A beauty means earlier onset, the main ingredients derived from petroleum wax, hand feels is not smooth and even feel some tingling, and stick in your hand there will be some oily feeling. Waxing can remove dirt paint surface, and increase the brightness.
    Sealing glaze: The main components of the glaze, also from the oil through a dedicated machine pressed into the glaze inside the paint, thereby forming a protective layer similar to the mesh, similar to the porcelain glaze layer and not understood by many people on. This play a protective layer to some extent isolated from ultraviolet light, isolated air oxidation, as well as reducing acid rain damage to the paint function.
    Coating: The main component of the membrane is a glass fiber material is known, specialized scientific name is called the all-silicon, nitrogen and hydrogen chloride, the operation when it is in liquid form, and can be cured to form a transparent protective layer on the paint surface , isolated from the outside world for the finish of the material damage, while protecting layer itself has a certain hardness, so the effect is more remarkable for the protection of some paint.
    difference on operating procedures
    Waxing process is relatively simple, clean paint can be operated. The more similar the glaze and seal coating process, if it is ahead of the need for polishing old vehicles (car without polishing), is relatively complex.
    Here it must be said that under Polish:
    Polishing with a polishing agent is abrasive particles with the help of polishing machine under friction with paint, remove the paint play dirt, polished smooth finish, polished surface refinement cross effect. Of course, the disadvantages are also obvious polishing is thinning the paint, a normal paint polish up about 6-10 times.
    Do keep in mind: car carrying sealed glaze or coating when not polished, good new transparent layer of paint is polished wasted in vain thickness. However, some older models due to the aging of the paint, polishing is necessary link.
    Waxing: First clean the body, and then the wax is applied to the rule of the paint, can be applied in the process of grinding away the remaining dirt particles of paint itself, the wax and then wiping with a dry cloth, the entire operation is completed.
    Closure glaze: sealing glaze and coating needs to be ahead of the car wash and polish (car without this step), polishing cream glaze after the completion of the machine via a dedicated internal hard pressed into the paint, repeatedly, making the glaze full access to the paint.
    Coating: the same as the sealed glaze, first, washing polishing, and then be subjected to degreasing treatment, the degreasing is called a polishing agent used in the polishing part of the paint remaining in the oily component was completely removed to ensure a good adsorption to the coating paint . After the completion of this part of the film evenly applied to a liquid paint surface, followed by high temperature dried, it will form a layer of transparent after drying and hard protective film.
    about the efficacy of maintaining time
    Waxing to maintain the shortest time, usually around a week or two, if you catch it rains or snows car wash, probably experience a becomes ineffective. Sealing and coating of glaze effects to maintain a little longer, sealing glaze can keep about six months, a good coating products can maintain 2-3 years.

It is like the same as the Autocom.
TCS CDP Diagnostic Tools Fetures & Benifits
This one do not have flight record function.
Multi Colour Indicator. With the multi colour indicator on TCS CDP, you have full control of the diagnostic process. Different colors and sound communicates the status and the placement of the indicator allows you to see it from a far. For example, if the indicator alternates between blue and green the TCS CDP is in communication with the vehicle control unit.
Connector With Led. To locate the diagnostic connector in the vehicle with ease, even if it’s located in a dark and inaccessible place, there is a LED on the 16-pin connector to help you along. The location and the design allows the light to function even when using the adaptor cable for vehicles without a 16-pin diagnostic socket.

Voltage Check. When TCS CDP is connected to the vehicle, the unit will check the battery voltage of the vehicle and automatically adjusts itself to the vehicle’s voltage level of 12 or 24 volts. If the voltage gets too high or too low,TCS CDP will warn you with both sound and light and you will also be alerted through the battery icon in our diagnostic software.
CHASSIS NUMBER VIN. In our CARS software, we have a smart function that allows you to read out the chassis number from the vehicle that you would like to diagnose. This ensures that the right model and year is selected automatically. In addition, engine code for vehicles, which are commonly available on the markets, is also selected automatically.
ISS. Intelligent System Scan (ISS) scans through all the systems in the vehicle and displays the fault codes that are stored in each system. This saves time and you get a quick overview of the actual status of the entire vehicle. When the ISS is complete, you can then select a specific control system to analyse the results further on.
ISI. Intelligent System Identification (ISI) identifies and selects automatically the type of controller that is mounted in the vehicle. This ensures that the diagnostic session is performed correctly with the correct parameters as required.
Report Function. Under this function tab, you will be able to see the adaptations and adjustments that are possible for a specific vehicle without having the vehicle near you. Together with the help texts as a guide, you can plan and be effective in your work; even under complex situations.
OBD-Funtions. TCS CDP is equipped with an unique multiplexer technology, which allows it to be used on all types of vehicles, regardless of voltage levels and communication standards. For those vehicles that do not use the standard 16-pin connector, we offer a complete set of certified and customized adapter cables and kits.

The car suddenly stalled terrible it is important to identify the cause

Remember that period of time just to drive it? Remember it has repeatedly flameout? Remember the oil from the place it? Remember the clutch is always fast and flame lift it? Here follow me look at the car is turned off in the end is how it happened ...... Honda HDS HIM Diagnostic Tool With Double Board
     Car flameout reasons:
     1, the automatic transmission models will not easily appear flameout phenomenon, and models due to manual driving level is not high, may often stall phenomenon. But do not rule out the automatic transmission car flameout phenomenon does not occur, mainly due to the use of the fuel poor (many gas stations in order to reap huge profits selling impure oil) lead to engine deposits and stall. Honda HDS HIM Diagnostic Tool With Double Board
     2 In addition, the reason for stalling the new car (automatic transmission) occurs mainly caused by driving skilled enough, another possibility is that the car engine or the oil problem, but for a new car, the possibility of a problem than the engine itself is small, because the passage of most of the problems. Honda HDS HIM Diagnostic Tool With Double Board
     3, the last for the old models, the flame is not enough because in addition to driving skill, but it is not up to the quality of the oil using the engine flameout set of carbon as a result.
     Automatic transmission car flameout troubleshooting methods:
     Usually pay attention to places: For automatic transmission vehicles stalling phenomenon is caused by the fuel or the use of poor quality. First, the formal larger stations plus high-grade oil, for example, using 95 gasoline, although the price a lot more expensive, but you can protect your car longer life and the exercise of the power of good. But some owners freeloaders 92 plus oil, although the price a little lower, but problems may occur in the future. The second is to pass a large gas station!
     Practice: left hand grasp the steering wheel to stabilize the direction (because there is no help, so be sure to firmly stabilize), right foot hard on the brakes to reduce the speed as much as possible, then quickly hit N AT stall speed, (note: the road to re-fight fire must be in the N range, can not be a D / R / P and other files, otherwise, the car or beat the fire, or the car will damage the gearbox), and then turn the key back a grid, and then re-ignition, then aT gear bit restored to normal driving D file. Honda HDS HIM Diagnostic Tool With Double Board
     Manual car flameout troubleshooting methods:
     1, for the novice, halfway flame is not a new topic, the main approach to rapid run-in after exclusion improve their driving skills.
     2, the use of high-standard quality of qualified fuel.
     3, a thorough cleaning of the oil line will include fuel injectors, throttle, fuel tank and so on. There may be you add the oil quality, but off, plastic fat too much, the oil passage blocked, the attack caused by poor oil.Honda HDS HIM Diagnostic Tool With Double Board
     4, the cause of the failure to turn off idling vehicles under mainly due to too much dust in the air, the engine is running at idle speed motor with the throttle valve seat at the deposition has many dirt, when excessive accumulation of dirt, the engine will be idling too low, idle stability is poor, idling flameout occurs when traveling. To solve this problem is simple: just wash idle speed motor can be.
     5, oil is smooth, it can easily lead halfway flameout.
     6, long-term car park is not used. In fact, should not be parked for a long time. If parked a long time, before re-use should do a thorough maintenance, oil changes, filter, etc., and, where appropriate check fuel circuit. Your vehicle may cause long-term parking is because lubrication or circuit problem.

More efficient! Single twin-scroll turbocharger turbine principle to resolve

Nowadays turbocharged engine is very hot, with more power than the same displacement naturally aspirated engine, by many people of all ages. The turbocharger as a core part of its evolution is constantly upgraded, as nowadays some of the equipment to launch a single twin-scroll turbocharger turbine. Single turbo twin-scroll turbocharger and the general principles of what would be different? And how about the engine performance impact? Let us resolve it.
Single twin-scroll turbocharger turbine structure

     Single turbo twin-scroll turbocharger with common structure similar turbocharger, exhaust gas can be simply understood as the entrance to a general increase in turbine exhaust passage, except that the turbine is driven by the exhaust gas of the two channels.
Exhaust gas turbocharger boost mode?
     Exhaust gas turbocharger on the engine intake supercharger There are two main ways that the constant pressure and pulse supercharger boost. Is the constant-pressure turbocharger turbine inlet pressure of the exhaust duct is almost constant, even though the exhaust gas of each cylinder alternately, but the pulse voltage is superimposed and the effect of the exhaust pipe, the inlet pressure of the turbine is almost change.
Pressurized pulses, each cylinder is discharged through the exhaust gases and at different moments of the forming pulse, the pressure before the turbine is changed, the pressure wave in a pulse manner to drive a turbine. Impulse supercharging turbocharger can achieve fast response characteristic (especially at a lower speed), because this time the pulse of the strongest, whereas in the case of constant pressure supercharging turbo mode after the pressure difference is relatively small.

     How to exhaust pulse generation?
     We know that the working cylinder four-stroke engine, only the exhaust stroke exhaust gases, the pressure before the turbocharger the exhaust gas passage of the cylinder only when the exhaust stroke is the largest. In a multi-cylinder engine, the exhaust gas due to the different time of each cylinder, and therefore the exhaust gas passage before the turbocharger the exhaust gas pulses will produce corresponding. Such as single-cylinder engine, in theory, each crankshaft rotation 720 ° in there 180 ° for exhaust. The following figure with a very simplified way to display a pressure situation cylinder engine exhaust gas turbocharger ago.
In the four-cylinder engine, since the crankshaft rotates two turns after completion of the respective all-cylinder exhaust gas loop, so produced within the 720 ° of the crank angle of the four pressure waves, uniform distribution of the ignition interval of 180 ° crank angle intervals. In this process, the pressure wave superposed on each other when the cylinder pressure falls to a next cylinder pressure has been increased.
Superimposed effect will make the minimum pressure and maximum pressure difference significantly reduced, and therefore the pressure wave acting on impulse turbine also will be reduced, leading to the exhaust turbocharger boost pulse within reduced.
Single twin-scroll turbocharger turbine produces larger pulse supercharger
     In a single twin-scroll turbine engine exhaust system, the exhaust duct is divided into two groups, such as the four-cylinder engine in the cylinder group 1 and 4, the cylinders 2 and 3 as a group, so that according to the ignition order, one channel the cycle interval of 360 ° crank angle, so even in the case of superimposed can produce a larger pulse supercharging, better utilization of the kinetic energy of the exhaust gas.
When the engine load is changed, the exhaust gas temperature and pressure changes can be quickly transmitted to the turbine, the turbine directly reflected by the compressor, so that a faster response of the turbocharger to changes in engine load, so that the engine can be improved better the acceleration characteristics and torque characteristics (low speed high torque can be generated).
Single twin-scroll turbo engine intake and exhaust design more efficient
     The above mentioned four-cylinder engine cylinder 1 and the cylinder 4, the cylinder 2 and the cylinder 3 are integrated in one channel, why should the cylinder 4 and the cylinder 1 together with the set, rather than the set of cylinders and the cylinder 2 together with? In fact, there is another advantage to do so. Autoboss V30 Elite Scanner For Multi-brand Vehicles for sale
We know that the four-cylinder engine firing order is 1-3-4-2, the general turbocharger (single turbo single scroll) is an exhaust manifold of an exhaust pipe of all the cylinders together and to the exhaust pooled and then to push the turbine.
What's so wrong with that? When the work of a single cylinder, the resonant pulse generated by the exhaust gas will affect the efficiency of the exhaust gas of the other cylinder. When working as a cylinder, there is a period of time the cylinder intake valve and exhaust valves are in the open state (valve overlap). If the ignition interval between the adjacent two cylinder exhaust pipe connected when the valve overlap causes the exhaust gas back into the preceding cylinders. Before a cylinder intake air reduction, then the next cycle of the total power will drop.
And in a single twin-scroll turbine engine exhaust system, the two cylinders adjacent to the ignition twenty-two separate exhaust duct (1 and 4, a group, a group 2 and 3), so that when the cylinder 3 is completed when the exhaust acting , a cylinder is entering the intake stroke, due to a cylinder and 3-cylinder exhaust pipe is not connected, so the three-cylinder exhaust does not affect a cylinder intake effect (other empathy), so the two adjacent ignition cylinder intake and exhaust without interference effects of intake can increase the displacement of each cylinder, thus effectively improving engine efficiency.

     Single twin-scroll turbo-charged engine characteristics
     BMW N20 turbo engine uses a single twin-scroll turbocharger technology, 1250 at low speed can reach 350Nm of peak torque (high power version), and can be continued until the 4800 revolution, covering almost daily driving use to the speed range. Autoboss V30 Elite Scanner
Single turbo twin-scroll turbocharging system, the ignition timing according to engine exhaust pipes adjacent cylinder exhaust pipes were divided into two groups to promote the turbine work, have a stronger pulse supercharger and exhaust more fully. Compared to ordinary turbocharged engine, single twin-scroll turbo engine effectively relieve hysteresis at low speeds, making the engine's peak torque outbreak earlier, better fuel economy.

Antilock braking system (ABS) and working principle

In the automotive braking, if the wheels from locking slip, lateral adhesion between the wheels and the road will completely disappear. If only the front wheel (steering wheel) brake to lock the rear wheels slip while still rolling, the car will lose steering ability. If only the rear brake to lock the front wheels slip while still rolling, even by small lateral disturbance force, the car will also have a slip (drift) phenomenon. These are easily cause a serious accident. Therefore, you do not want the car when braking wheel brake to lock slip Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool, but hope to edge trim wheel brake slip state.
     By experiment that, car wheel slip rate at 15% to 20%, between the tire and the road surface friction coefficient has the largest. So in order to give full play to the ability of this potential adhesion between tire and road, currently on most vehicles are equipped with anti-lock braking system (AntilockBrakeSystem), referred to as ABS . our shop supply Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool
     ABS composition and working principle
     Typically, ABS wheel speed sensor is the installation of the braking system on the basis of the ordinary, ABS electronic control unit, brake pressure regulating device and other components of the brake control circuit.
     During braking, ABS electronic control unit (ECU) 3 continuously obtained from the wheel speed sensor 1 and the signal 5, and processed, to analyze whether there is a wheel is about to lock the slide drag.
     If no trailer wheel slip is about to lock, the brake pressure regulating means 2 is not involved in the work, the brake master cylinder of the brake cylinders 7 and 9 in communication, the brake wheel cylinder pressure continues to increase, namely, ABS braking process the pressurized state.
     If the electronic control unit determines that the individual wheels (assumed to be a left front wheel) is about to drag the locking slide, namely a brake pressure regulating means which issues a command to close the left front brake master cylinder and the wheel brake cylinder passages and the front left system wheel cylinder pressure no longer increases, namely ABS braking process of packing state.
     If the electronic control unit determines that the locking of the left front wheel tends to drag the slider still state, namely it issues a command brake pressure regulating means, to open the left front wheel brake cylinder and the reservoir chamber or the accumulator (not shown) the channel, so that the left front wheel cylinder braking oil pressure decreases, namely, the pressure during ABS braking condition.
ABS hydraulic control assembly structure ,to buy Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool visit our shop www.obd2works.com
     ABS hydraulic control assembly is in the hydraulic unit on the basis of ordinary braking system designed after the installation of ABS brake pressure regulator formed.
     Hydraulics ordinary braking system generally includes brake booster, brake master cylinder, double chamber, reservoir chamber, brake wheel cylinder and dual hydraulic lines and so on. In addition to the hydraulic braking system outside an ordinary member, ABS brake pressure regulator usually consists of an electric pump, the accumulator, the main control valve, the solenoid control valve and some control switches and other components. Essentially, ABS system is controlled by a hydraulic control valve solenoid on the valve body Cylinder quickly becomes larger or smaller, in order to achieve the anti-lock braking function.
     (1) electric pump
     The electric pump is a high pressure pump, which can be pressurized brake fluid in a short time (in the storage vessel) to 15 ~ 18MPa, and the entire hydraulic brake system provides a high pressure liquid. Electric pump can be started in the car to complete the work within one minute. Electric pump operates independently of the ABS computer, computer failure or wiring if there is a problem, the electric pump can still work.
     (2) the accumulator
     Diverse forms of energy storage structure. Autel MaxiCheck Airbag ABS SRS Light Service Reset Tool used more as a piston - spring-accumulator, the accumulator located between the solenoid valve and back to the pump, the wheel cylinder to the hydraulic fluid into the accumulator, thereby compressing the spring so that the hydraulic accumulator cavity volume change large to temporarily store the brake fluid.
     (3) solenoid control valve
     The electromagnetic control valve is an important component of the hydraulic actuator, it is done by the control of the ABS. ABS systems have one or two solenoid valve, which has a plurality of solenoid-controlled valve, the front and rear wheels, respectively, brake control. There are three commonly used three-way solenoid valves and two two-way valves and other forms.
     (4) pressure control, pressure and level warning indicator switch
     Pressure control switch (PCS) working independently of the ABS computer, monitoring the pressure of the lower chamber of the accumulator. Pressure Alarm Switch (PWS) and level indicator switch (FLI) function is, when the pressure drops to a certain value (14MPa or less) or when braking level drops to a certain extent, the fault indicator lights and ABS braking system fault indicator, while allowing the ABS anti-lock brake computer stops working.
