Abstract

PURPOSE: To reduce the amount of Nox contained in exhaust gas and improve the starting performance of a several-cylinder diesel engine by providing a pilot fuel injection system of a fuel injection pump.
CONSTITUTION: A pilot fuel injection system assembled between an injection pump and an injection nozzle consists of a spill fuel intake passage 60, a pilot fuel communication passage 63, a pilot check valve 71 set in the pilot fuel communication passage 63, a fuel cut-off solenoid valve 73 set in the pilot fuel communication passage 63, and an electric circuit 74 for operating the solenoid valve 73. Before starting, the solenoid valve 73 is operated to send the spill fuel in the pump barrel 37 from a relief hole into the pilot fuel communication passage.
