M-series engines are among the most effi cient in the market. Fuel consumptions of 212 g/kWh testify to the optimized combustion process. 6-hole VCO nozzles, as well as the monoblock single pumps, and the optimized combustion chamber geometry all make their contribution to this. Without a pre glow system the engines start reliably as low as -10°C; with a pre glow system and corresponding resources even -32°C is no problem.
The integrated, intelligent, mechanical automatic engine protection protects the engine. When a cooling fan malfunctions, there is not enough oil, or the inclination is too high, the engine is automatically stopped to prevent engine damage.
