The STEYR - M1 engines have been developed without compromise for the most selective markets, ambient conditions and operation profiles. Our strategy was to select the most durable heavy duty materials for the core engine and to design the whole surroundings in light weight materials, compact and without "ad-on"- compromises. For this we have chosen Monoblock from special alloy Unit injectors, mechanically driven but electronically controlled with injection pressures up to 2000 bar Oil pan as a lower sound encapsulation, carries all auxiliaries and reduces noise and vibration All of these together with the experience of our highly skilled engineers resulted in lowest weight in the class ( less 1,2 kg / HP ) unrivalled compact dimensions highest power density ( up to 81 HP / lt.) lowest fuel & oil consumption on top in reliability & operational safety
