1. The difference between diesel engine and gasoline engine: the ignition method is different, gasoline engine is to breathe the gasoline steam into the cylinder and air mixed, pressurized, and then ignition with spark plug. The diesel engine is composed of diesel mist emitted by the fuel nozzle and air mixed, pressurized, by compression to increase the temperature of the mixed gas automatic ignition.

2. Compared with gasoline, diesel power is larger, higher ignition point, less volatile. Due to these characteristics, the fuel economy of diesel engines is 30% higher than that of gasoline engines. In other words, the same vehicle, under the same driving conditions, assume that the fuel consumption of the gasoline car is 10L, and the fuel consumption of the diesel car is about 7L.

3. Different ways of gas mixing. The general gasoline engine is mixed with air outside the cylinder into the cylinder, while the diesel engine is injected directly into the cylinder and mixed with air. Different ignition methods. An oil engine requires a spark plug to ignite the gas mixture, while a diesel engine ignites via compression spontaneous combustion. Power and torque are different.

4. The following is the specific difference between diesel engines and gasoline engines: fuel supply and ignition mode: diesel fuel mixing and combustion is carried out in the cylinder. From the injector directly to the combustion chamber injection of high pressure diesel fuel and air mixed to form atomized gas is compressed and burned, so in the structure of the gasoline engine than the diesel engine more than a set of ignition system.

5. The gasoline engine is the use of the nozzle above the electronic igniter to generate electrical sparks, igniting gasoline to achieve the purpose of ignition. Electrical components are required. Fuel consumption: Compared with gasoline, diesel has high power, high ignition point, and is not volatile, because of these characteristics, diesel engines have 30% higher fuel economy than gasoline engines.
