ABSTRACT:
We provide a torch cell for a dual gas-liquid fuel engine, the torch cell has a torch cell nozzle at one end thereof and the other end having appropriate means to connect said torch cell to a fuel supply. A fuel injector is mounted in said torch cell at a predetermined angle to an axis of said torch cell. The torch cell has an auto-ignition chamber that is in operative communication with the injector by an injector nozzle passageway. The injector nozzle passageway enters the auto-ignition chamber at a predetermined angle relative to the cell axis. The torch cell provides an improved dual fuel engine and method for operating a dual fuel engine by use of its autoignition chamber. We also provide a cylinder head which can replace present dual fuel engine cylinder heads. Our cylinder head has at least one of our torch cells operatively connected to the cylinder head.
