How does a diesel engine add fuel to the compress air and it is ignited?

Diesel engine doesn't have spark plug as like petrol engine . But It has an atomizer (A plug through which fuel is sprayed into the combustion chamber).... During Intake Stroke ,the vacuum caused by piston draws air (only) into the cylinder ,Now during Compression stroke Atomizer comes to play ,Spraying Diesel into the cylinder meanwhile the piston compresses the air, so that it's temperature rises to such extent that diesel could be ignited by the heated air, and there comes the power stroke and so on...
So ,Conclusion is that Diesel Engine doesn't use spark plug, but the increase in temperature of air during compression is enough to ignited the diesel..

How is diesel fuel ignited in a warm diesel engine?
Compression.
How is the engine ignited?
A petrol engine is ignited by a spark plug, and a diesel engine is ignited by the heat produced from the air/ fuel mixture being compressed in the cylinder
Why is carburetor used in petrol engine but not in diesel engine?
a petrol engine needs to mix its air and fuel before passing it into the combustion chamber before being ignited diesel has its air mixture heated as the piston compresses it in the combustion chamber then the atomized diesel fuel is injected into the hot air and is ignited.
What is the difference between diesel fuel and diesel?
Diesel is a type of internal combustion engine wherein the fuel is ignited solely by heat produced by rapid compression of the air in the cylinder. Not by an electrical spark as in a gasoline engine. As the cyl air is compressed the air becomes heated. Fuel is injected into the hot cylinder and is ignited by the heat alone
In what type of engine is the air and fuel mixture ignited by the heat created during the compression stage?
diesel
What happens when diesel fuel is placed in a gasoline tractor engine?
It won't run, that's for sure. Diesel is ignited by compression pressure, not by spark. And the compression in a gasoline engine is not sufficient to ignite the diesel.
How fuel is ignited in diesel engine?
Just due to the heat of Compression. The fuel is Injected at a point where the air temp is high enough the fuel burns.
In a diesel engine the air fuel mixture is ignited by?
It is ignited by compression. The air fuel mixture is compressed by the piston going up. Some diesels have glow plugs too that heat up the air fuel mixture so it is more easily ignited.
What lights the fuel in a diesel engine?
Diesel fuel is ignited by a combination of heat and compression. The heat is caused by the very high compression in the cylinder. The fuel also has to be very finely atomised to be able to burn.
Why petrol engine is called spark ignition engine?
Because the fuel is ignited by a spark plug rather than by compression as is the case with a diesel.
Why do diesel engine has a greater noise than gasoline engine?
The fuel is ignited by compression and not by a spark plug. The compression of the cylinders is much higher than in a gas engine. The fuel must be compressed to the point at which it will ignite. This cause the noise you hear from a diesel engine.
What is a 8 cylinder engine?
It means that there are 8 pistons the simataniously go up an down in the block to compress fuel while its ignited by your spark plugs
