Because of their efficiency and durability, diesel engines have become the standard in powering our nation’s trucks and buses.
Diesel engine maintenance is becoming increasingly complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely heavily on microprocessors to maximize fuel efficiency. In most shops, workers often use computers to diagnose problems and adjust engine functions.
Diesel technicians handle many kinds of repairs. They may work on a vehicle’s electrical system, drive-train, HVAC, steering, suspension, make major engine repairs, or retrofit engines with emission control systems to comply with pollution regulations.
In addition to electronic diagnostic equipment, diesel technicians use a variety of power and machine tools, such as pneumatic wrenches, lathes, grinding machines, and welding equipment. Hand tools, including wrenches, hammers, pry bars, torque wrenches and micrometers, are also commonly used.
