MAN Energy Solutions has unveiled a dual-fuel model of its MAN 175D high-speed engine, able to working on methanol, that is scheduled to develop into out there to the market by the top of 2026. The new variant, designated MAN 175DF-M, can be out there each as newbuild and retrofit variants.
MAN Energy Solutions states that the 175DF-M can be optimized for diesel-mechanical and diesel-electric propulsion to attain the biggest methanol share and finest effectivity for numerous purposes and cargo profiles. The engine has already been awarded the ‘fuel ready’ certificates by DNV.
Florian Keiler, Head of High Speed, MAN Energy Solutions, stated, “The MAN 175D has proven to be very competitive in terms of sustainability and efficiency with the lowest fuel consumption, lowest lube-oil consumption and longest overhaul times in its class, minimizing its environmental footprint. In terms of future fuels, the next logical step, apart from being able to run on 100% bio-fuels, is to ensure methanol combustion.”
MAN Energy Solutions is creating a methanol-ready engine portfolio because the demand for such know-how has quickly been rising. With its success in reaching series-approval for its two-stroke engines, MAN Energy Solutions has used this expertise to develop an optimized answer for its four-stroke engines, together with profitable single-cylinder testing. As such, the outcomes of those efforts will gasoline the upcoming growth and validation of the dual-fuel PFI (Port Fuel Injection) know-how for its methanol-ready 175D engine.
Keiler stated, “Based on numerous exchanges with customers, we came to the conclusion that the dual-fuel principle, reliability, efficiency, a high methanol share, competitive life-cycle costs and maximum achievable output were key requirements for the 175DF-M’s development. Therefore, after conscientious investigation and consideration, we settled upon the PFI combustion technology as the most favourable. Fundamental combustion development will start in 2024, leading up to a first field-test of the methanol engine in 2026. The MAN 175DF-M engine will subsequently be ready for sales release at the end of 2026.”
