What is a CI engine?

A CI engine is an engine in which the fuel charge is ignited by the heat of compression. The process of combustion in the CI engine is fundamentally different from that in a spark-ignition engine. In a CI engine, the air is let into the combustion chamber and compressed to very high pressure.
