Abstract: A nozzle injection apparatus for use in internal combustion engines includes a fuel pump for intermittently pressurizing fuel and an injection conduit in fluid communication with the fuel pump, the injection conduit permitting the pressurized fuel to be communicated to a fuel injection nozzle. A high pressure manifold in fluid communication with the fuel pump and the nozzle is also provided to accumulate the pressurized fuel which is residually left in the injection conduit between intermittent pressurizations of the fuel. The apparatus has low opening and closing pressures when starting the engine while ensuing high opening and closing pressures during operation of the engine. Further, the apparatus maintains high residual pressure in the injection conduit which provides higher than normal pressure to the nozzle at the end of a fuel delivery cycle to subsequently reduce exhausted pollutants.
