What engine does Xiamen Jinlong van use for gasoline and diesel?

(1) The gasoline used in Xiamen Jinlong van is Mitsubishi, Mianyang and Toyota.

(2) Diesel oil includes Yuchai and Great Wall 2.8T.

The difference between diesel engine and gasoline engine;

(1) diesel engine: mainly depends on pressure, air and diesel oil;

(2) Gasoline engine: mainly depends on gasoline, air, pressure and spark.

(3) Working principle of diesel engine: Air enters the cylinder and is compressed by the piston. After learning physics, you will know how high the temperature of high-pressure compressed air is, about one to more than two hundred degrees. When the compression is finished, the oil pump injects a good high-pressure diesel mist into the cylinder. At this time, it will burn because of the high temperature in the cylinder, producing explosive gas to push the piston to do work and so on.

(4) Working principle of gasoline engine: gasoline passes through carburetor or injector to form oil mist, which is sucked into cylinder together with air, compressed by piston and reaches the end of compression stroke. At this time, the spark plug ignites, and the compressed combustible mixture burns in case of fire, producing explosive gas to push the piston to do work.

(5) The diesel engine is just an oil pump, which is a little more complicated (in fact, contrary to the principle of the engine, it needs external force to drive the oil pump to rotate, and the piston is driven to inject oil through the crankshaft cam, which is similar to a medical injector). The rest is nothing! Gasoline engine is a multi-point ignition system, but with the development of technology, ignition is controlled by computer from the initial distributor. Distributor is a rotating device installed at the end of camshaft. When the engine rotates, it is driven to rotate, which discharges the high-voltage coil, so that the high-voltage coil generates induced current and finally leads to the spark plug. There are several kinds of computer control, crankshaft position sensing or infrared ray. However, it depends on sensing where the engine turns and which cylinder needs to be ignited.

(6) Diesel engines are powerful and bulky, but their speed is low, so they are generally used on carts. Gasoline engines are small in size, low in power but high in speed, and are generally used in automobiles.
