Diesel Engines Yesterday, Today, and Tomorrow Diesels are workhorse engines. That’s why you find them powering heavy-duty trucks, buses, tractors, and trains, not to mention large ships, bulldozers, cranes, and other construction equipment. In the past, diesels fit the stereotype of muscle-bound behe-moths. They were dirty and sluggish, smelly and loud. That image doesn’t apply to today’s diesel engines, however, and tomorrow’s diesels will show even greater improvements.

They will be even more fuel efficient, more flexible in the fuels they can use, and also much cleaner in emissions.
