Yes of course the diesel engine are also know as the compression engine, and so only the compression ratio of the diesel engine are high.

Compressor ratio of diesel engine have so high, mixture of air and diesel reach self burning temperature.

In diesel engines the fuel get burnt itself when the atomizer spray it, this is due to the air is too much compressed, as the atomizer introduces fuel in the cylinder it immediately catches fire and creates power stoke of the cycle, hence it's CI engine.

In diesel engine due to compression of air only the pressure and temp of air increases and when fuel is sprayed instant ignition takes place.

The compression ratio of diesel is very high between 12-22.
That's why it burn in very less compression so it doesn't needs spark plug.
Fuel burns only by heat created during compression.
That's why it is known as compression ignition engine.

Diesel fuel cannot be ignited through spark as done in petrol engines.
So its is first intake to combustion chamber is air and then its compressed then at end of compression stroke diesel fuel at high pressure ratio its injected in to the combustion chamber in sprinkled form thus fuel gets ignited.

In the compression ignition engine air-fuel mixture is not pass together in engine, In engine comes under mixture and its cycle is also changes for constant pressure that's way it is CI engine.

In the compression ignition engine air fuel mixture burn due to high compression ratio, compressed air temperature higher than self ignition temperature of fuel.

Compressing in a closed cylinder air gots maximum temperature perhaps fuel is high pressurised injected in a closed cylinder that causes combustible take place.

In diesel engine first compressed at high temperature of fuel then it is injected in combustion chamber.
