Can the car catch fire for a while and not catch fire for a while?

Recently, everyone is concerned about "can the car catch fire for a while and not crash?" The relevant content is explained as follows. Because the atomization effect of injected fuel is not good when the cold machine is started, a large amount of liquid fuel enters the cylinder. This causes the mixture around the spark plug to be too thick to reach the ignition limit, and the car will not start:

1, stepping on the accelerator is to increase the opening of the accelerator and increase the air intake, but the dirty accelerator will obviously limit the increase of air intake. Just like you breathe, it's natural that your nose is blocked and the air inhaled into your lungs is reduced.

2. At this time, you need to clean the throttle to remove the carbon deposit on it and let the air enter the cylinder more freely. Secondly, there may be a problem with the fuel system;

3. The fuel pump is damaged and the oil circuit is not smooth, which will lead to insufficient oil supply and insufficient fuel to participate in combustion, resulting in low concentration of mixed gas. This situation is the same as the situation of high concentration. It is difficult for the spark plug to ignite the mixture, and the car still can't hit it.

4. Therefore, if you want to reduce the concentration of mixed gas, you need to inject more air into the cylinder. Generally speaking, it is not enough to only rely on the starter to drive the crankshaft to do the intake stroke, because the rotation speed is not fast enough and the intake suction of the cylinder is weak.
