That's your average Diesel, or compression ignition engine.
The air and fuel mixture is ignited by the heat created during the compression stage in a compression ignition engine, also known as a diesel engine.
Diesel
The gas vapor air mixture enters the cylinder during the intake stroke of the four-stroke cycle. This mixture is then compressed during the compression stroke before being ignited by a spark plug, leading to combustion and generation of power during the power stroke. Finally, the exhaust gases are expelled during the exhaust stroke.
Yes, during the compression stroke.
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
As a kid I was always told: Suck-Squeeze-Bang-Blow!Induction, Compression, Expansion (or Ignition), ExhaustAs the piston is drawn down, the inlet valve opens and fuel mixture is drawn in with fresh air. (with turbo engines, it's pushed in)Piston rises and the inlet valve closes compressing the gasesAround tdc the mixture is ignited (spark - Petrol or by the heat caused during compression - Diesel) and the piston is forced down by the expanding (ignited) gasesPiston rises and the exhaust valve opens to allow the burnt mixture to be forced out.
During the compression stroke in an engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the gases, making them more volatile and ready for combustion when the spark plug ignites the mixture.

Regular fuel, gasoline, is more flammable and is usually ignited by a spark plug. Diesel fuel is a "heavier" fraction of the crude oil and is usually compression ignited when used in a regular piston engine. This means that the engine first draws in air, then compresses this air quite a lot. During compression the air heats up to the point wherei it will ignite once ignited.
Intake valve must be open to allow atomized fuel mixture to enter cylinder--than all valves are closed during compression stroke 4- stroke engine 1) intake valve open to allow fuel mixture to enter cylinder 2) compression stroke all valves closed 3) ignition stroke mixture is ignited by spark from spark plugs 4) exhaust stroke--exhaust valve is open to allow residue to escape
Adiabatic compression occurs when a precisely controlled mixture of a flammable gas and oxygen are ignited by the heat of colliding molecules during the compression of said gas. This causes an explosion and the explosion causes an expansion of the gasses. These expanding gasses must force their way out of confinement and pushes a piston. This turns tirns a crank shaft which will mechanically open and close intake and exhaust valves through push rods.
