INTAKE MANIFOLD CLEANING DEVICE FOR COMMON-RAIL DISEL ENGIN

摘要

PURPOSE: A cleaning device of an intake manifold for a common rail diesel engine is provided to prevent engine output and the flow velocity of suction air from decreasing by removing soot through a chemical reaction. CONSTITUTION: A cleaning device of an intake manifold for a common rail diesel engine comprises a fuel filter(3), a fuel injection nozzle(12), a solenoid valve(13), and a controller(20). A fuel pipe is directly connected to a fuel tank(1) or branches from a fuel line(101) which is connected from the fuel tank to a fuel pump(4). The fuel injection nozzle connected to the end portion of the fuel pipe injects fuels to the inner surface of the intake manifold. The solenoid valve opens or closes the fuels injected from the fuel injection nozzle. The controller controls the inflow quantity of the fuels by opening and closing the solenoid valve while transmitting electric signals to the solenoid valve.
