Engine profile: MaK M 20 C

摘要

When the MaK M 20 was originally launched in 1992 it represented the first of a new medium-speed long-stroke marine diesel portfolio that today comprises the M 20, M 25, M 32 and M 43 engines. Of some 1200 M 20's sold to date — almost half of which are operating on heavy fuel oil — roughly 60% are for genset usage and 40% for main propulsion. In 1995 Caterpillar revised the design, which brought about a 10% power increase combined with lower emissions in line with IMO regulations. Now after some 14 years in service, the engine has undergone a further revamp.
