<p>A naturally aspirated or supercharged dual fuel engine operates on Diesel and liquefied petroleum gas (LPG) respectively. The LPG fuel supply is controlled by an accelerator pedal position sensor/switch and a Diesel fuel pressure actuated switch. The supply of LPG can be cut-off during idle and transient engine operations by closing two solenoid valves in the gaseous fuel supply system in order to reduce the overall fuel consumption.</p> |
