ABSTRACT:
We provide a torch fuel cell for a dual gas-liquid fuel engine, the torch fuel cell being positioned internally of the variable volume chamber formed by the cylinder, piston and cylinder head which accepts and is adapted to compress the air/gas mixture forming the main fuel source. Preferably, the torch fuel cell is carried by the piston at, or adjacent to, the end face thereof. Suitable means are provided to deliver liquid fuel into an auto-ignition chamber in the fuel cell and other means for delivering the thermal and chemical products of such auto-ignition into the variable volume chamber to ignite the main gaseous fuel source.
