Diesel engines are more efficient and more durable than regular fuel-burning engines, and specially trained diesel mechanics are needed to repair and maintain them.

Besides being used in semis and buses, diesel engines power locomotives, construction vehicles such as bulldozers and dump trucks, farm equipment such as tractors and combines, and light, diesel-driven passenger cars and trucks. Diesel engine mechanics are thus needed in nearly all areas of automotive repair and maintenance.

One increasingly common part of diesel mechanics is electronics repair, since many modern diesel engine functions are guided by on-board computers, electronic sensors and other high-tech devices. To stay up to date with modern diesel technology, diesel mechanics must be familiar with these areas, as well as most systems covered in general automotive training. Smog regulation equipment is also a growing part of diesel mechanics, and technicians are expected to be capable in that arena as well.

Here is some general information on diesel mechanics, including career and salary information.
