摘要： A fuel control system is provided for use with an internal combustion engine having at least one cylinder, a source of gaseous fuel and an intake passageway for fluidly connecting the air intake to the combustion cylinder. The control system includes a gas flow rate sensor which generates an output signal representative of the fuel flow rate to the engine as well as a mass air flow sensor which generates a signal representative of the mass air flow rate to the engine. A fuel valve is fluidly connected in series between the source of gaseous fuel and the air intake passageway. The fuel valve is actuated by an electrical pulse stream between an open and a closed position so that the duty cycle of the pulse stream is proportional to the amount of fuel supplied to the engine. In response to the fuel flow rate signal, the air flow rate signal and a target air/fuel ratio, the control system generates PID gain scheduling parameters relative to the duty cycle of the pulse stream. The system then varies the duty cycle of the pulse stream as a function of the PID gain scheduling parameters to obtain the target air/fuel ratio. Optionally, an air/fuel sensor generates an output signal representative of the actual air/fuel ratio supplied to the engine. This signal is compared to the target air/fuel ratio and utilized to generate second PID gain scheduling parameters to further modify the duty cycle of the pulse stream in order to obtain the target air/fuel ratio.

摘要： In a center injection type of direct injection engine, since it has an ignition plug and an injector arranged in proximity, there occurs the problem that a sprayed liquid fuel directly strikes the ignition plug and causes the plug to misfire. A notch is to be provided at a portion of the injector end so as to form a coarse-grained portion and a dense portion in sprays of fuel, and the injector is disposed so that the coarse-grained portion is directed towards the ignition plug. It is possible to avoid the misfiring of the ignition plug and thus prolong the life of the plug, by preventing a liquid fuel from directly striking the plug.
