MAN Diesel & Turbo has extended its dual-fuel engine programme with an ME-LGI unit that can run on liquid fuels.
The new ME-LGI concept can be applied to all MAN Diesel & Turbo low-speed engines, either ordered as an original unit or through retrofitting. With two new injection concepts, the ME-LGI concept greatly expands the company's dual-fuel portfolio and enables the exploitation of more low-flash-point fuels such as methanol and LPG, MAN said.
The engine's 'ME-' prefix indicates that the new engine benefits from well-proven electronic controls that also encompass the fuel being injected by a booster fuel injection valve. Specially developed for the ME-LGI engine, the fuel booster is said to ensure that a low pressure fuel-gas supply system can be employed, significantly reducing first-time costs and increasing reliability.
MAN Diesel & Turbo states that it is already working towards a Tier-III-compatible ME-LGI version.
