Characteristics of traditional diesel engines

Thermal efficiency and economy are better. The diesel engine uses compressed air to increase the air temperature so that the air temperature exceeds the auto-ignition point of diesel. At this time, diesel is injected, and the diesel spray is mixed with air and ignited by itself. Therefore, diesel engines do not require an ignition system. At the same time, the fuel supply system of the diesel engine is relatively simple, so the reliability of the diesel engine is better than that of the gasoline engine. Because it is not subject to knocking restrictions and the need for diesel spontaneous combustion, diesel engines have a high compression ratio. Thermal efficiency and economy are better than gasoline engines. At the same time, under the same power, diesel engines have large torque and low speed at maximum power, making them suitable for use in trucks.
