What is the Principle of a Diesel Engine?

Diesel engines operate on a similar working process as gasoline engines, with each working cycle also going through four strokes: intake, compression, power, and exhaust. However, since diesel engines use diesel fuel, which has higher viscosity than gasoline and is less prone to evaporation, and its auto-ignition temperature is lower than that of gasoline, the formation of the combustible mixture and the ignition method differ from those of gasoline engines. Here is some relevant information: 1. Advantages: Diesel engines are known for their high power and good economic performance. The working process of diesel engines shares many similarities with gasoline engines, with each working cycle also undergoing the four strokes of intake, compression, power, and exhaust. 2. Ignition Method: Since diesel engines use diesel fuel, which has higher viscosity than gasoline and is less prone to evaporation, and its auto-ignition temperature is lower than that of gasoline, the formation of the combustible mixture and the ignition method differ from those of gasoline engines. The main difference is that the mixture in a diesel engine cylinder is ignited by compression rather than by spark.

What are the major systems that make up a car?

A car consists of five major systems: 1. Fuel supply system: According to the requirements of the engine, it prepares a certain quantity and concentration of the air-fuel mixture to be supplied into the cylinder and exhausts the burned gases from the cylinder into the atmosphere; 2. Lubrication system: It delivers a specific amount of clean lubricating oil to the surfaces of moving parts to achieve liquid friction, reduce frictional resistance, minimize wear of components, and clean and cool the surfaces of parts; 3. Cooling system: It dissipates part of the heat absorbed by heated components in a timely manner; 4. Ignition system: The combustible mixture in the cylinder is ignited by an electric spark. The gasoline engine's cylinder head is equipped with a spark plug, the tip of which extends into the combustion chamber, capable of generating an electric spark between the electrodes at the right time; 5. Starting system: The process from when the crankshaft begins to rotate under external force until the engine starts to idle automatically is called engine starting. The device required to complete the starting process is called the engine's starting system.
