- Engines powered by diesel fuel are much more efficient than engine fueled by gasoline. Diesel engines are the standard engine for trucks, trains and buses. In recent years, diesel engines have been more frequently found in passenger vehicles and pick-up trucks.
- A diesel mechanic is responsible for repairing and maintaining diesel engines. This includes 18-wheelers and buses. Many diesel mechanics work on heavy construction or farm equipment like bulldozers and tractors. Diesel engines also power boat motors.

It is becoming increasingly important for the diesel mechanic to service newly developed technologies. Diesel engines are largely comprised of electronic components, which makes maintaining the engines more complex. A diesel mechanic is also required to retrofit engines to comply with current emissions standards.
There are many tools that a diesel mechanic uses in the practice of his trade. These include pneumatic wrenches, lathes, welding equipment and computerized engine analyzers. - Depending upon the specific work environment, a diesel mechanic may be responsible for a number of duties within the scope of the job description. The mechanic may have to repair vehicles on location; lift heavy equipment, parts or tools; handle extremely greasy diesel engine components; and endure long periods of lying down or standing in order to complete a repair. A diesel mechanic may also frequently experience minor injuries, such as cuts or bruises. Safety procedures within the workplace should ensure that serious accidents are prevented, although safety must be exercised at all times.
- A diesel mechanic who has graduated from a formal training program will be hired and advanced more quickly than one who has not had formal training. This formal training can come in the form of high school curriculum emphasizing automotive repair as well as certificate or associate programs in diesel engine repair at the local community/technical college. The average hourly earnings of diesel engine mechanics is between $18 to $20 per hour; some mechanics earn more and some earn less. Entry-level mechanics will earn about half of what their more experienced counterparts will earn.
