Is Your MaK^™ Engine Ready for What’s Next?

High Pressure Direct Injection (HPDI)

Methanol and ethanol are lower-carbon alternative fuels that, when produced from renewable sources, offer a significant reduction in CO₂ emissions. We offer the HPDI retrofit kit for direct injection of methanol and ethanol — this converts a conventional diesel engine into a dual fuel engine for methanol and ethanol operation to help customers reach compliance with the latest EU regulations. No matter how complex your fuel transition needs, we’re ready to guide you through with expert engineering and support.

Fuel Blending solutions

Blending is a retrofit solution that supports compliance with future emissions regulations by mixing methanol/ethanol with marine diesel oil (MDO) upstream of the engine. A dedicated blending module creates a stable emulsion with fine droplets ensuring reliable combustion and safe operation through the engine’s conventional fuel system. The module monitors and controls the entire fuel flow in real time, regulating blend ratios and maintaining stable performance. This approach enables the use of lower-carbon fuels without altering the engine’s core architecture, offering a practical and flexible pathway to reduce GHG emissions.

Drop-in fuels support sustainability objectives without any technical modification and can extend engine life without disruption. All MaK series engines (current and legacy) can burn these fuels due to their durable and reliable design. These types of fuels include bio-derived, such as HVO, or synthetic fuels. The blends are delivered ready-to-use and do not require onboard mixing. They offer reduced GHG emissions and are compatible with existing systems, which means reduced downtime for your operations.
