FUEL-INJECTION SYSTEM FOR AN INTERNAL-COMBUSTION ENGINE |
摘要 |
The injection system comprises a high-pressure pump with variable flowrate, having at least one pumping element provided with an intake valve in communication with an intake pipe and a delivery valve in communication with a delivery pipe. A pressure regulator is set on the intake pipe downstream of a metering solenoid valve designed to meter the flowrate of the pump according to the operating conditions of the engine. The pressure regulator is designed to discharge the excess fuel into a compartment of a crankcase for lubricating the usual actuation mechanism of the pumping element. Set between an inlet of the solenoid valve and an inlet of the pressure regulator is a control volume designed to contain an amount of fuel such as to guarantee an adequate flow of fuel in an area corresponding to the inlet of the solenoid valve.
