Whether it is a diesel engine or a gasoline engine, they are all driven by the internal piston that pushes the cylinder after combustion, so that the chemical energy in the fuel can be converted to be able to drive the vehicle. The mechanical energy is OK. However, because the ignition point contained in gasoline is relatively high, when a spark plug is needed in a vehicle's engine to ignite it, there will be a power output for the engine of the vehicle that explodes very well. The energy needed during the march is called ignition. And when it comes to diesel, its ignition point is not as high as that of gasoline. Diesel oil is compressed air to increase the temperature of the air, so that when the high temperature is over the ignition point of the diesel, then in the When it is injected into diesel and it is air mixing and diesel spray, it ignites itself again, which is called compression ignition. Therefore, the diesel engine does not require an ignition system such as a spark plug.
The pressure on the diesel fuel injection nozzle is greater than the fuel injection pressure of the gasoline engine. If the diesel fuel is added to the gasoline engine, the pressure of the fuel injection nozzle will not be enough, so it will cause The atomization of diesel is not good enough, and only part of the atomization can be performed. Some parts of the diesel oil enter the cylinder with a liquid state. Because diesel fuel is not sufficiently burned, carbon deposition is prone to occur. In severe cases, it can cause clogged injectors. of. When driving a vehicle in such a situation, it will feel the powerlessness of the engine of the vehicle, which is caused by insufficient combustion of diesel fuel.
Finally, because the ignition point of diesel is relatively low, and when the spark plug is able to reach the temperature at which it can spontaneously ignite before the diesel is ignited, it will start to burn itself, which is what we often say The earthquake situation. This kind of driving situation will not make you feel comfortable, and it will also cause damage to the vehicle's engine.
