ABSTRACT:
Residual pressure control means corresponding in number to the cylinders of the engine are connected between the delivery valves of the fuel injection pump and the respective injection pipes. The residual pressure control means are interconnected in an arrangement corresponding to the sequence of fuel injection through the delivery valves. Each of the control means is adapted to transfer the injecting fuel pressure present therein on its injection nozzle side to its next control means when the same injecting fuel pressure exceeds the injection fuel pressure present therein on its injection pump side at the termination of each fuel injection, to obtain increased injection pressure of fuel injected by an injection nozzle associated with the above next control means during the immediately following fuel injection.
