Development of DEUTZ MWM 616 High-Performance Diesel Engine Series

Querschnitt TBD 616

Extensive Experience, Diverse Deployment Possibilities


Based on the extensive experience with the DEUTZ MWM 234 engine series, the fast-running 616 diesel engine series was developed in 1995. The predecessors of this series had been deployed for various purposes, e.g. in construction machinery, locomotives, ships, and stationary equipment. The experience gained proved valuable for the design of the new 616 diesel engine series. To enable high efficiency and more eco-friendly operation, four-valve technology with center-aligned injection nozzle was introduced. Moreover, the engine displacement was enlarged compared to the predecessor series 234, and the engine was implemented as a long-stroke engine with high-pressure injection. The new high-performance diesel engines met all requirements of the TA-Luft (Technical Instructions on Air Quality Control). Based on an exhaust oxygen content of 5 percent, NOx emissions were less than 2,000 mg/Nm3.
