FUEL SUPPLY METHOD AND DEVICE FOR CYLINDER INJECTION TYPE INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To inject fuel at predetermined high fuel pressure in an operation range from cranking to lasting operation after complete explosion. SOLUTION: I a fuel injection device for a cylinder injection type internal combustion engine provided with a high pressure fuel pump 3 and directly injecting fuel of which pressure is raised by the high pressure pump 3 from an injector 2 into an engine combustion chamber, a electric motor 4 supportingly driving the high pressure fuel pump 3 and drive or driving torque of the high pressure fuel pump 3 is assisted by the electric motor 4 at start of an engine.
