3 Compression Ignition (Diesel) Technology Compression Ignition (C.I.), better known as “diesel” engines do not use an ignition system for combustion of fuel in the cylinders. C.I. Engines ingest air without fuel. When the air is compressed by the piston during the compression stroke, fuel is injected into the cylinder. The heat of the air compression process causes the fuel to combust spontaneously, this drives the piston downward and powers the engine. Combustion timing is controlled by the timing of fuel injection into the cylinder.

8 C.I. Engine Advantages C.I. engines have several advantages over gasoline engines: They burn less fuel than a petrol engine performing the same work They have no high voltage electrical ignition system They generate less waste heat in cooling and exhaust The carbon monoxide content of the exhaust is minimal Jet A cylinder lubrication properties
