Information about diesel fuel injection

One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburettor. A port injection system injects fuel just prior to the intake stroke (outside the cylinder).

A carburetor mixes air and fuel long before the air enters the cylinder. In a car engine, therefore, all of the fuel is loaded into the cylinder during the intake stroke and then compressed.

The compression of the fuel/air mixture limits the compression ratio of the engine -- if it compresses the air too much, the fuel/air mixture spontaneously ignites and causes ‘knocking’. Because it causes excessive heat, knocking can damage the engine.

Diesel engines use direct fuel injection -- the diesel fuel is injected directly into the cylinder. For more information from Auckland's diesel fuel injection experts, contact us today.
