Diesel Technology  

The Diesel Technology program offered at Wyotech is designed to provide students with the specialized knowledge and mechanical skills necessary to troubleshoot, maintain, and repair today’s modern diesel engines and power systems. Students will have the opportunity to get their hands dirty working on diesel engines and heavy machinery manufactured by industry giants like Cummins, Caterpillar, Detroit Diesel, John Deere, and more.  

In the classroom, students receive in-depth lectures on diesel engine theory and design, principles of operation, power train principles, shop setup theory, and more. Through lively discussions, detailed textbooks, class projects, and written assignments, students develop critical thinking, reasoning, and problem solving skills, while deepening their understanding of technical mathematics and writing.

Topics of study include gear ratios, U.S. Standard and Metric measuring systems. Students in the Diesel Technology A.A.S. Applied Service Management Program will also learn how to write a successful business plan, locating investors, service writing, job costing, accounting, budgeting, financial management, record keeping, financial management, pricing and marketing, effective shop management, OSHA standards, and more.

In the state-of-the-art lab, students observe live demonstrations and gain practical hands-on training in engine trouble diagnosis and engine analyses, carefully guided by their instructors as they learn how to troubleshoot, diagnose, and repair diesel engines, engine management systems, brakes, Rockwell anti-lock brake systems, Eaton anti-lock brake systems, air systems, charging systems, starting systems, fan clutches, front-ends, chassis, power trains, drive train systems, Detroit Diesel electronic systems, Cummins electronic systems, Peterbilt systems, Kenworth systems, and more. 

Using technical manuals, hand tools, pneumatic wrenches, sophisticated diagnostic equipment, precision measuring devices, wiring schematics, and electronic multi-meters, students acquire valuable hands-on experience in diesel engine overhaul and tune-up, as they disassemble, inspect, diagnose, repair, and reassemble various diesel engines from Cummins, Caterpillar, Detroit Diesel, John Deere, and more.

Each student will strengthen their mechanical, analytical, and technical skills throughout the hands-on training portion of the program. Students will also practice shop safety and effective time management as they complete each task assigned to them by their instructors in a thorough manner with accuracy and precision. Work ethics, professionalism, and maintaining a positive workplace attitude will also be stressed throughout the Diesel Technology program at WyoTech.
