Burning oil is a common problem, but when it is ignored, it can do major damage to your car's engine. Many drivers reflect that the car burns oil, therefore, we will give you a detailed explanation of the main causes for engine burning oil. The symptom of car burning oil The main symptom of oil burning in an engine is blue smoke from the exhaust pipes. Engine shakes while idling, and engine oil is severely lacking during a routine maintenance (oil change) cycle (no dripping). Then your car is burning oil. The main causes of the engine oil burning There are two causes of engine oil burning: 1. Positive wear and tear, that is, it is the normal symptom after driving a certain number of miles for a car. The average vehicle is above 200,000 kilometers, different cars, different people use, different regions (air dust) have a great impact on the service life of the engine. For the normal wear and tear of vehicles over a certain service life and mileage, should be overhauled.

Driving on the road will inevitably encounter some unexpected breakdown. In some cases, we need to go to the car service center immediately, and in the other cases, you can do it yourself. If you are in a remote suburb or not convenient to go to car service center when your car has a fault, it is particularly important to learn these simple troubleshooting skills by yourself. Learn and master some simple emergency repair methods will come in handy at the critical moment.

From experience with vehicles, more than half of all petrol engine breakdowns are caused by unclean fuel. All petrol has some moisture in it. Some of this water is produced during the refining process and some is caused by external factors. At normal temperatures, the fuel dissolves some water.

In general, automatic gearboxes do not stall easily, while manual gearboxes may stall frequently due to poor driving. It cannot be completely ruled out that automatic cars stall. Regardless of the type, the main cause of stalling is basically due to the use of poor quality fuel, which causes the engine to build up carbon and stall.

In the early engine fuel supply system, the fuel pump was mostly mechanical. However, the function of the fuel pump is to transfer the fuel stored in the fuel tank to the injector, and then distribute the fuel to the combustion chamber. Now electric fuel pump has been replaced the mechanic fuel pump, in addition, because some of the original electric fuel pump installed outside the fuel tank, considering the heat dissipation, sound insulation and air resistance and other problems, the fuel pump is installed into the tank, combined with the fuel and fuel meter measuring device as a whole. However, the failure of fuel pump will cause the engine unable to start or difficult start, engine flameout, surge, unstable speed, idling engine wobble, poor acceleration, detonation, insufficient power, excessive fuel consumption, excessive emission and other faults, so the original electric fuel pump installed outside the fuel tank was replaced. We take the Volkswagen as example.

To ensure that the fuel system is clean, the fuel tank should be drained regularly of contaminants as well as water and sediment from the fuel pre-filter. It is strictly forbidden to use any tools to tighten the drain valve when draining the pre-filter, and to open the drain valve all the way when draining the water.

When the engine is working, if the load decreases, open the return valve, the negative pressure of the intake manifold increases, then the pressure acting on the side of the diaphragm spring chamber decreases, under the system oil pressure, the diaphragm moves up and opens the return valve, so that the excess part of the fuel flows back to the gasoline tank through the return pipe from the outlet.

Fuel is an indispensable substance for the movement for a car, but the fuel itself contains impurities, moisture and other compositions. When these things exist in the fuel tank and the fuel pipe for a long time, will form oil sludge and sediments. In addition, due to the olefins in gasoline, oxidation and polymerization will occur at high temperature, resulting in the formation of some sticky substances. Once these substances stay in the injector nozzle, air inlet valve and other parts for a long time, these substances will become carbon deposition when burned, damaging the engine performance. Therefore, it is very important to maintain the fuel system regularly.

When the automobile engine is not working normally or car won't start and the self-diagnosis system has no fault code output, it is especially necessary to rely on the operator's inspection and judgment to determine the fault type and the fault location. We summarizes the engines common faults as follows: Fault phenomenon: turn on the ignition switch and put the ignition switch to the starting position, the engine won't start. Possible causes of failure include the starting system failure, ignition system failure, fuel injection system failure, air inlet system failure.

First, let's take a brief look at the fuel system: the function of the fuel system is to supply the engine with a certain amount of clean, well-atomized gasoline to mix with a certain amount of air to form a combustible mixture, based on the operating conditions of the engine. At the same time, the fuel system also needs to store a considerable amount of gasoline to guarantee the car's long driving range.
