A special control technology allows the DF50 engine to run on a very lean air/fuel mixture by adjusting fuel consumption to suit operating conditions. Equipped with MPS EFI multi-point sequential fuel injection, engine self-diagnosis system, fully transistorized ignition system. The special design of the oil pump contributes to more efficient oil passage, better lubrication of moving parts without wasting energy. Reducing mechanical losses results in better fuel economy and reduced emissions. The advanced fuel economy technologies used in the DF50 create all the conditions for maximum efficiency, reliability and environmental friendliness.
