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 the reliability and lifetime expectations of the M 43 C while maintaining its class leading position regarding operational efficiency. With its clean design, the M 46 DF does allow fast and easy access to the system and components supporting the 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 will meet 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.
