The diesel engine is known for its exceptional thermal efficiency, which makes it one of the most efficient internal combustion engines available. This high efficiency is achieved through a large expansion ratio and a lean burn process that allows excess air to help dissipate heat. Unlike two-stroke gasoline engines, diesel engines avoid fuel loss during valve overlap, as there is no unburned fuel present. Low-speed diesel engines, commonly used in marine applications, can achieve thermal efficiencies over 50%, making them ideal for heavy-duty use.
