Diesel Technology

The Rend Lake College Diesel Technology program is designed to provide students with the technical knowledge and work skills needed to enter the diesel engine repair and maintenance field. This mechanical-field program is structured with both lecture and laboratory experience and leads to either an Associate in Applied Science Degree or an Occupational Certificate.
College personnel take great pride in the fact that most work is based on realistic live-work situations. Emphasis is placed on hydraulics, diesel fuel systems, transmissions and power trains, diesel engine maintenance, diesel engine electronics and computerized engine controllers in relation to the modern technology of today’s industry. Associate degree course work includes one semester of supervised occupational experience (on-the-job training).
