The Diesel Mechanic trade in ITI (Industrial Training Institute) is a practical and job-oriented course that trains students in the repair, maintenance, and servicing of diesel engines used in vehicles and machines such as trucks, tractors, buses, generators, and heavy equipment. The course usually has a duration of one year, divided into two semesters, and the minimum qualification required is 10th pass. During the training, students learn about the construction and working of diesel engines, fuel injection systems, cooling and lubrication systems, engine overhauling, battery and electrical systems, and the use of workshop tools and safety practices. After completing the course, students can work in automobile workshops, truck and bus service centers, tractor agencies, transport companies, and generator repair shops, or they can start their own diesel engine repair garage or service center. The trade also provides opportunities for apprenticeship and further studies in automobile engineering or advanced technical training.
