Diesel Engine Repair & Performance

(Prerequisite: Gasoline Engine Class)

Similar to the gasoline engine, diesel engines mechanically work the same. The difference lies in how fuel is ignited. In a gas engine, air and gas are mixed together, compressed, and ignited by a spark plug. In a diesel engine, air is compressed at double the pressure of a gas engine, then fuel is injected at a very high pressure. These high pressures ignite the fuel, which eliminates the use of a spark plug. This creates lots of power while being very efficient.

Diesel, however, has a downside: It creates lots of pollutants. In 2007 the EPA required that all trucks have diesel particulate filters and by 2010 all trucks must have emission systems to lower Nitrogen Oxides (NOx) produced by the engine.

This course is designed to go over all the mechanical aspects of an engine by completing a teardown and rebuild of an engine followed by identifying the systems of the engine, including:

 

  • Cooling System

  • Lubrication System

  • Fuel System

  • Intake & Exhaust Systems

  • Ignition System

  • Timing System

  • Emissions Control Systems

  • Computerized Engine Controls

  • Cylinder Head & Valve Train

  • Engine Block
