© 2017 Superior Diesel Companies

As fuel injection specialists, we focus on the repairs and servicing of diesel injection pumps, injectors and related components.

 

We are  factory authorized by all of the major fuel injection equipment manufactures.

 

Today's equipment is no longer powered by the noisy, smoky engines of forty years ago. Modern diesel engines are sophisticated, high-tech systems requiring the care of highly skilled, trained professionals.

 

With the integration of sophisticated electronic engine management systems, we've broadened our approach to include on-engine repairs of agricultural/industrial equipment and on-highway vehicles ranging from diesel cars and pickup trucks to Class 8 trucks.

 

We recognize the need to employ new testing systems, new service technologies and technicians trained in the latest technologies.

 

Embracing these changes has earned us a reputation in West Michigan for superior quality products and outstanding service.

How a Fuel Injector Works

One big difference between a diesel engine and a gas engine is in the injection process. Most car engines use port injection or a carburetor. 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.

The injector on a diesel engine is its most complex component and has been the subject of a great deal of experimentation -- in any particular engine, it may be located in a variety of places. The injector has to be able to withstand the temperature and pressure inside the cylinder and still deliver the fuel in a fine mist. Getting the mist circulated in the cylinder so that it is evenly distributed is also a problem, so some diesel engines employ special induction valves, pre-combustion chambers or other devices to swirl the air in the combustion chamber or otherwise improve the ignition and combustion process.
