ABSTRACT:
In a fuel injection nozzle having an outwardly opening poppet valve that controls the delivery of fuel to an engine combustion chamber, a piston increases the difference between the injection pressure required to initiate opening of the poppet valve and the injection pressure required to fully open the poppet valve. The piston effectively limits opening of the poppet valve during light load engine operation, thereby reducing the rate of injection during light load engine operation and thus enhancing the ability of the engine to operate with low noise, hydrocarbon and nitrogen oxide emissions.
