A, inferior gasoline is prone to deflagration. I've tried some cars, whether they are cold or hot, idling in place and filling up urgently, and I may hear knocking on the cylinder. )
B, the engine temperature is too high, the combustion speed and pressure in the combustion chamber rise, which will also cause deflagration.
C. When the engine runs for a long time at a low speed and a short distance, a large amount of carbon deposits will gradually form in the engine and combustion chamber. Because carbon deposits occupy the space of the combustion chamber, the compression ratio of the engine will increase, which will eventually lead to the increase of combustion temperature and pressure. At the same time, due to the heat insulation effect, when the engine runs at high speed, the carbon deposit keeps the heat of the last work. When the mixture is compressed to a certain pressure and temperature, the heat stored by carbon deposits will ignite the mixture, forming irregular combustion and causing abnormal detonation. Also known as spontaneous combustion and multipoint combustion. Cylinder knocking (irregular "banging" and "clanging" metal knocking in the engine) is mainly caused by knocking, which will suddenly produce knocking in the cylinder and impact in all directions, making the piston side of the engine knock on the cylinder wall to produce abnormal noise, and at the same time, the connecting rod and crankshaft will produce strong vibration and impact, accompanied by metal knocking.
