WebThermal efficiency is better as higher compression ratios are achieved. Manufacturers of heavy-duty lean-burn gas engines include MTU, Cummins, Caterpillar, MWM, GE Jenbacher, MAN Diesel & Turbo, Wärtsilä, Mitsubishi Heavy Industries, Dresser-Rand Guascor, Waukesha Engine and Rolls-Royce Holdings . Honda lean-burn systems [ edit] A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached with less fuel, while giving a longer expansion cycle, creating more mechanical power output and lowering the exhaust temperature.

The efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase.
