How does a diesel engine work?
One
Four-stroke diesel engines
There are two types of diesel engines: four-stroke and two-stroke. His inventor was Rudolf Diesel, who invented a process called the “Diesel cycle”. This cycle is based on a higher compression ratio of air.
The heat generated by this compressed air can reach temperatures of 390°C to 710°C. Sometimes the temperature can be even higher. Below is the 4 stroke of a diesel engine.
Stroke #1
The first cycle of the diesel cycle is virtually the same as the gasoline cycle. The inlet valve opens and outside air flows in. The lower cylinder receives this air through the downward movement of the piston, drawing air into the cylinder.
Stroke #2
The second subscript contains compression. After the intake valve closes, the air is compressed as the piston rises. There is a small, limited space in this area that allows for higher compression.
Stroke #3
Stroke #4
The fourth stroke is concerned with exhaust. All the exhaust gases generated are pushed out by the piston through the open exhaust valve. This creates the infamous black smoke that diesel vehicles are known for. This smoke comes from the exhaust pipe (of the semi-trailer).
Conclusion
The same thing applies here. With a diesel engine, you don’t have to worry about spark plugs. That might be one less maintenance thing you have to worry about. This will help you get the most out of your diesel engine’s lifespan.
