Electronic Fuel Injection for Dual Fuel Diesel Methane

An electronic fuel injection system for diesel engines has been adapted for dual fuel applications. The simplified and commercially practical system capitalizes on using standardized hardware and software modified for the dual fuel conversion kit Using the conventional diesel pump for pilot injection, electronic injectors provide timed pulses of gas for each cylinder.

The system has been successfully applied to both naturally aspirated and turbocharged versions of the Mercedes OM-352 diesel engine and has been placed in service in transit bus applications. Performance data shows over 90% displacement of diesel fuel with the same power and fuel economy as the base diesel engine. Initial reports from the field indicate excellent performance and drivability as well as smoke-free exhaust when in the dual fuel mode.
