The DF90 benefits from our Lean Burn Control System which enables the engine to operate on a lean air-fuel ratio or a thinner mixture of fuel. The system controls the air to fuel mixture by predicting fuel needs according to operating conditions. It delivers its benefits over a wide operating range providing significant improvements in fuel economy from low speed operation well up into the cruising range, which all helps to reduce your fuel bills.
