W engines with indirect injection to reduce emissions.
Air-cooled 3 to 6-cylinder naturally aspirated engines in inline arrangement.
Capacity: 1.1 l/cylinder, modular system with single cylinders.
The robust engine design allows worldwide operation even with high sulphur fuels.
Low noise emissions due to acoustically optimized components with very smooth running and high durability.
Highly efficient injection and combustion system ensures optimum engine performance at low consumption.
Flywheel and end 100% power takeoff possibilities PTO drives for hydraulic pumps and compressor possible, only a few maintenance points, long oil change intervals.
Very compact engine design reduces the installation costs. 
Best cold starting performance even under extreme conditions.
The W engines fulfil the requirements of the China stage II.
