New | M 46 DF Marine Generator Set

Based on the successful M 43 C MaK medium speed engine, the M 46 DF was designed by Caterpillar Motoren, Kiel, to meet and exceed reliability and lifetime expectations of its predecessor, while maintaining its class leading position regarding operational efficiency. With its clean design, the M 46 DF allows a fast and easy access to the system and components, supporting operation, service and maintenance simplicity MaK products are known for. Designed to operate on gaseous- as well as liquid (MDO HFO) fuels, the M 46 DF meets IMO III emission limits while operating in gas mode and injecting a small amount of ignition fuel to control combustion. Attention was paid to the customers´ demand for a safe and reliable operation at varying engine loads and gas qualities.
