How does a diesel engine differ from a gasoline one?
Because of the type of fuel as well as the design of the engine itself, a diesel engine operates at lower internal temperatures. This helps lengthen the lifespan of the engine block. In addition, there are no spark plugs and associated ignition parts, which reduces maintenance. A diesel engine also has fewer moving parts, which also helps increase engine life as well as reduce maintenance. And, diesel fuel is often less expensive at the pump than gasoline.
