Abstract
The fuel injection system employs a relief valve which is connected to the fuel chamber in the injection valve containing the primary fuel. The relief valve opens towards the end of the primary fuel injection phase to connect the fuel chamber to a discharge duct. Further, the relief valve permits a flushing of the fuel chamber after a changeover from operation with a coal slurry suspension to operation with diesel oil as the primary fuel. A selector valve, a pair of three way valves and multiple reservoirs are provided to accommodate switching over of operation from coal slurry to diesel oil.
