Abstract

A separate metering and metering unit for a diesel and/or propane or similar gas/liquid fuel powered internal combustion engine such as a dual fueled engine incorporates an intake filter, a lockout solenoid, and a metering device into a single integrated unit remote of the carburetor of the engine. The metering unit includes a heater immediately adjacent to the output of the injector metering device in order to provide heat necessary to prevent any freezing of the unit injector or gaseous fuel or oxidizers downstream of the metering unit. The injection of the propane allows for correct operation of a catalytic converter.
