Ignition principle of diesel engine

The ignition method of gasoline engine is to ignite with a spark plug after the compression stroke, and do work! The ignition principle of diesel engine is that the intake stroke, that is, the valve opening, fills the cylinder with air at 1; 2. In the compression stroke, the piston moves upward under the action of the crankshaft, and the compressed air reaches a high temperature; 3. During the power stroke, diesel oil is directly injected into the cylinder through the fuel injector to mix with air. At the end of the compression stroke, the ignition point of diesel oil is low and the cylinder is compressed. Diesel oil comes into contact with high-temperature gas, and the piston is compressed and deflagrated upwards to push the piston to move downwards to do work. 4. During the exhaust stroke, the exhaust valve is opened, and the waste after work is discharged from the cylinder. Repeat the above four strokes continuously to ensure the power output of the engine and make Xiangqian Che! I hope the above answers are helpful to you. Please keep asking questions!
