The combustion process in a diesel engine comes in four steps 1.Suction 2.Comression 3.Power 4.Exhaust these are called as strokes when the piston travells from top end to bottom end Respectively.
1.Suction : In this stroke the fresh air through the aircleaner from the atmosphere which is sucked by the piston (when the valve opens)when the piston travells from TDC to BDC (TOP to BOTTOM) get trapped inside the cylinder(Combustion chamber) and valve closed.
2.Compression : In this stroke the air which is trapped inside the cylinder (when the both valve are closed)getting hot due to compression by the piston when it travells from bottom to top it gets hotter.
3.Power : In this stroke the hot air now comes in contact with fuel when the injectors sprayes the fuel in a fine automized form and the fuel gets burnt by a higher temperature upto 600 degree C.
4.Exhaust : In this stroke the exhaust valve opens when the piston travels from TDC to BDC and pushes the burnt gases out through the exhaust valve exhaust manifold scilencer and then to the atmosphere.

The main difference between a diesel and a steam engine is the diesel engine is an internal combustion and the steam engine is external combustion.
The diesel combustion pressure depends on various factors. The model and the type of diesel engine is important.
The auto combustion pressure for a diesel engine is 580 psi. This is compared to the 200 psi of the gas powered engine.
The diesel engine doesn't have any spark plugs, and uses heat generated during compression to ignite the fuel. The diesel however, is an internal combustion engine.
Type of combustion is determined by the engine, not the fuel. Intermittent or reciprocating engines such as those found in cars and trucks can run on diesel. Gas turbines AKA jet engines can also run on diesel however they are continuous combustion engines. The answer to your question depends on the type of engine you have in mind. If it has pistons then it will be intermittent.
Combustion of instantly compressed diesel vapour or gas
In 1898, Rudolf Diesel was granted patent #608,845 for an "internal combustion engine" the Diesel engine. Born in France, grew up in Germany.
That process is called 'internal combustion'

Diesel Engine combustion chamber types : Swirl port combustion chamber type and Preignition port combustion chamber type.
Petrol and diesel engines are internal combustion engines. The internal combustion that turns the engine and powers the wheels is created by the combustion of fuel. No fuel, no combustion, and nothing to drive the wheels.
