Gasoline and diesel engines Engines are two common engines we have.

In addition to burning diesel, what are the differences between diesel engines and gasoline engines?

The engines used on ships and trains are all so-called "compression ignition" engines, which are often referred to as diesel engines.

The efficiency of diesel engines is greater than that of gasoline engines, and it is much larger. Compared with the size of cars, ships and trains running on the road, it seems that they are not at the same level at all. . Moreover, diesel engines do not use spark plugs and carburetors.

In addition to these advantages, all the oil used in gasoline engines is low-grade oil, which is much cheaper than gasoline.

Any kind of gas will generate heat when compressed, so the pump used in bicycles will also generate heat after being pumped for a long time.

The principle of diesel engine is like this.

The air entering the cylinder of the diesel engine will become very hot after being compressed by the piston. At this time, the oil is pumped in and sprayed out in the form of fine mist. It will burn immediately when it encounters hot compressed air.

Combustion or expansion causes the piston to move backward along the cylinder, thereby transmitting power to the crankshaft. When the piston moves upward, the exhaust gas is discharged and circulates again.

The cycle process is that air enters the cylinder, the air is compressed and injected into the oil fuel, the oil fuel explodes to generate power, and the exhaust gas is discharged from the cylinder.
