The four-stroke engine cycle.
Compression and ignition
Air and fuel intake, compression and ignition, combustion and expansion, exhaust
Compression ignition is deisel. Otherwise, spark ignition is gasoline.
air and fuel intake, compression and ignition, combustion and expansion, exhaust
Air and fuel intake, compression and ignition, combustion and expansion, exhaust
Intake, compression, power/combustion, exhaust. Same as a standard SI (Spark Ignition) CI (Combustion Ignition) is how diesel operates. They contain no spark plugs. The compression heats the fuel to the point of SELF COMBUSTION .
I think you have a typographical error in your question. The question I believe is "What is a compression ignition engine?" The answer is:- A diesel engine is a compression ignition engine.
intake, compression, ignition, exhaust
Compression
Compression Stroke
Air flow in to and out of the engine, adequate compression, fuel and ignition.
SI engine means Spark Ignition Engine where combustion products(air,fuel)are ignited in combustion chamber by means of spark from spark plug which is located on cylinder head..CI engine means Compression Ignition Engine,here combustion is take place by means of compression..
