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.

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
