Abstract:
PCT No. PCT/AU93/00649 Sec. 371 Date Aug. 17, 1995 Sec. 102(e) Date Aug. 17, 1995 PCT Filed Dec. 14, 1993 PCT Pub. No. WO94/13946 PCT Pub. Date Jun. 23, 1994An engine control unit for a gas fuelled internal combustion engine detects engine speed, throttle position, manifold absolute pressure, gas pressure, gas temperature, battery voltage, air temperature, engine phase and boost pressure control valve feed back position. The control unit calculates a percentage full load value for the engine based upon the detected engine speed and throttle position and utilizes the calculated percentage full load value to calculate the injector on time for each gas injector in a gas delivery system for the engine. Typically, the control unit employs the percentage full load value and the engine speed to calculate a required manifold absolute pressure value, and this calculated manifold absolute pressure value may then be employed together with the percentage full load value to calculate a percent allowable load value. The engine control unit employs the percentage allowable load value to calculate injector on time and spark advance for the engine.
