Technician A says large, low-speed industrial diesels require a high-quality and highly volatile fuel because they cannot tolerate excessive carbon deposits that result from low-volatile fuels. Technician B says the small, high-speed diesel engines found in passenger cars are relatively unaffected by carbon deposits and can run on low-quality fuel. Who is correct?

Question

Quizplus · Accepted Answer

Large, low-speed industrial diesels actually can tolerate lower-quality fuels better than small, high-speed diesel engines. High-quality and highly volatile fuel is more critical for small, high-speed diesel engines found in passenger cars to prevent excessive carbon deposits and ensure efficient operation.
