What is the reason why a car will stall when it steps on the accelerator?

The engine flameout may be caused by dirty air filter, blockage, or small dirty throttle opening, resulting in insufficient engine air, insufficient combustion of combustible mixture and engine flameout. In this case, it is best to go to a 4s shop to find a professional to solve it.

Precautions before starting the engine:

First, avoid that there is no cooling liquid in the water tank or adding cooling liquid after the engine is started, which will make the hot cylinder liner, cylinder head and other important parts burst or deform due to sudden cooling. Similarly, if you suddenly add 100 to the cold body? C boiling water will also crack the cylinder head and cylinder block.

The correct way is to add coolant before starting the engine. The selection of coolant should refer to the requirements in the attached operation and maintenance manual. It is forbidden to add tap water, warm water and other domestic water sources to the engine. It is recommended that you choose long-lasting organic coolant.

Second, avoid not supplying oil according to regulations. Do not put the decompression handle when starting the engine or after starting it. Work? Before fuel supply, put the throttle handle in the fuel supply position before starting the engine.

The hazards of not operating according to this regulation are: when starting, if the oil supply is increased at the beginning, fuel will be wasted, excess diesel will scour the cylinder wall, worsen the lubrication between the piston, piston ring and cylinder liner, and aggravate the wear. The remaining engine oil will dilute the engine oil, reduce the lubrication effect, and cause excessive diesel in the cylinder to burn incompletely and accumulate carbon.

The correct way is: warm up first, then refuel the valve, and then start it.
