Essential Information
Diesel technology programs cover topics like air condition systems, diesel engine technology and diesel fuel systems. They may have laboratory components that allow for hands-on skills building in a lab or garage. Standard admissions requirements apply to each program, but generally, a high school diploma or equivalent is required for admission to both programs. An associate's degree may transfer to a bachelor's program.
Associate of Science in Diesel Technology
Degree programs in diesel technology are typically offered through 2-year technical, vocational and community colleges. They help students learn the techniques and develop the practical skills necessary to troubleshoot and repair diesel-powered vehicles. Students learn first-hand how to diagnose mechanical issues in diesel trucks, develop plans for repairing trucks and manage the service of diesel engines. The courses taught in an associate's degree program in diesel technology are most typically offered within a lab or garage environment. Some specific courses include:
- Diesel engine technology
- Fuel systems
- Heavy duty brakes
- Commercial truck power train
- Diesel air conditioning systems
- Power transmissions
Bachelor of Science in Diesel Technology
Bachelor's degree programs in diesel technology aren't as common as associate's degree programs; however, some schools do offer such programs to students who want to get a core understanding of diesel repair methods and techniques while gaining a well-rounded education in mathematics, natural sciences and humanities. Some 4-year programs at this level are oriented toward those who would like to move into the management side of mechanics. Students enrolled in a diesel technology program gain a theoretical introduction to diesel engines as well as practical training. Some courses might include:
- Diesel engines lab
- Diesel fuel systems
- Hydraulics and pneumatics
- Diesel electrical systems
- Diesel shop management
- Heavy duty automatics
Popular Career Options
An associate's degree program in diesel technology can prepare graduates for several jobs working with diesel automobiles. These include the following positions:
- Heavy truck technician
- Diesel mechanic
- Diesel engine manufacturer technician
- Diesel service and parts manager
- Fuel systems specialist
Employment Outlook and Salary Info
According to the U.S. Bureau of Labor Statistics (BLS), diesel engine specialists, in addition to bus and truck mechanics, held 281,300 jobs in the country in 2019 (www.bls.gov). They primarily worked for general freight trucking companies, local government agencies, automotive repair shops and motor vehicle wholesalers. The median annual salary in the field in 2019 was about $48,500. According to the BLS, the employment of diesel service technicians and mechanics is expected to grow by 3% from 2019 to 2029.
Certification Options
Diesel mechanics and technicians aren't required to earn certification before finding a job. However, gaining national certification from an organization such as the National Institute for Automotive Service Excellence (ASE) can provide job seekers with an additional edge. The ASE can certify diesel mechanics in brakes, steering systems, electrical systems and preventive maintenance.
Training in diesel mechanics is available at the associate's and bachelor's degree levels, although some bachelor's programs are designed for individuals who want to work in mechanics management. Graduates are eligible for careers as diesel mechanics, fuel systems specialists and heavy truck technicians.
