    摘要： In a two-way utility internal combustion engine, method and apparatus employing an accumulator-type fuel injector having an accumulator cavity and a control cavity both of which are pressurized with fuel to about the same pressure, fuel pressure in the accumulator cavity applying upward force on the needle, and fuel pressure in the control cavity applying opposing downward force on the needle. The accumulator and control cavities are pressurized by means of a reciprocating plunger pump wherein the plunger is driven by cam lobe means on the crankshaft, and injection is initiated by venting fuel from said control cavity through a two-way solenoid valve. Injection mass is varied by variation of the ignition timing relative to pump plunger top dead center. Engine power output is varied between full power and idle by skip-firing, which is caused by noninjection of fuel in the engine cylinder during one or more engine crankshaft cycles during a series of a predetermined number of crankshaft cycles.
