摘要： Supply of fuel is stopped when fuel pressure sensed by a pressure sensor provided upstream of a regulator is at a predetermined value or less to avoid abnormal combustion caused by improper adjustment of air/fuel ratio. Even slight variation of the fuel pressure is sensed by monitoring the fuel pressure in an interval after closing a fuel shut-off valve once opened to re-opening of it. In addition, an abnormal state in the fuel system is detected by comparing an accumulated value of amount of injected fuel and an estimated value of fuel consumption in the tank. Furthermore, the peak current value of the fuel injection valve is controlled so that, when the engine at a low temperature is started, lift load of the injection valve is larger than sticking force of the injection valve, thereby preventing such situation where the injection valve is frozen so that it cannot supply fuel to the engine. In this case, the engine can be smoothly started by simultaneously controlling the valve open time. Furthermore, the temperature of the regulator is properly maintained so that optimum function can be exhibited by controlling the flow rate of cooling water flowing through a water passage provided in the regulator for regulating the fuel gas pressure.
摘要翻译：在设置在调节器上游的压力传感器检测到的燃料压力为预定值以下时，停止供给燃料，以避免由于空气/燃料比的不当调整引起的异常燃烧。通过在关闭燃料切断阀一旦打开以重新打开之后的间隔中监视燃料压力来检测燃料压力的轻微变化。另外，燃料系统中的异常状态是通过比较燃料喷射量的累积值和燃料消耗的估计值来检测的。此外，控制燃料喷射阀的峰值电流值，使得当低温发动机开始时，喷射阀的升程负荷大于喷射阀的粘附力，从而防止了喷射阀被冻结，使其不能向发动机供应燃料。在这种情况下，可以通过同时控制阀打开时间来平稳地起动发动机。此外，适当地保持调节器的温度，从而通过控制流过设置在用于调节燃料气体压力的调节器中的水通道的冷却水的流量来显示最佳功能。

摘要： A fuel injection method wherein optimum fuel injection timing in a fuel-injection type gas fuel engine is determined by setting fuel injection end timing to be after the start of opening of an intake valve. That is, when injection ends in a first half of the intake valve open period the volumetric efficiency .eta.v falls and the engine output also falls, because the injection period overlaps with a period of positive pressure arising inside the intake pipe before opening of the intake valve, but when injection ends in a second half of the intake valve open period the volumetric efficiency .eta.v rises and the engine efficiency also rises, because the injection period overlaps with a period of negative pressure arising in the intake pipe during the first half of the intake value open period. Consequently, when fuel is injected during this trough in the intake port pressure, the volumetric efficiency increases and the engine output also increases by several percent.
摘要翻译：一种燃料喷射方法，其中燃料喷射型气体燃料发动机中的最佳燃料喷射正时通过将燃料喷射结束定时设定为在开阀开始之后。也就是说，当进气阀打开期间的前半部分的喷射结束时，体积效率等级下降，并且发动机输出也下降，因为喷射周期与在进气口打开之前在进气管内部产生的正压时间重叠但是当喷射在进气阀打开时段的后半段结束时，容积效率η升高并且发动机效率也上升，因为喷射周期与进气管在上半年期间产生的负压时间重叠摄入量开放期。因此，当在进气口压力期间在该槽内喷射燃料时，容积效率增加，发动机输出也增加了几个百分点。

摘要： A control apparatus for an electric motor provided with a rotator having a permanent magnet and with a stator for generating a rotating magnetic field by an applied voltage and revolving the rotator includes: a rectangular wave inverter that applies a rectangular wave voltage onto the stator of the electric motor to drive the electric motor; a voltage converting section that raises or lowers an output voltage of a direct-current power supply and applies the voltage onto the rectangular wave inverter; an electrical angle acquiring section that acquires an electrical angle of the rotator of the electric motor; and an output voltage command generating section that generates a command for instructing the voltage converting section to output an electrical-angle synchronized voltage whose amplitude ripples in synchronization with a change of the electrical angle of the rotator acquired by the electrical angle acquiring section. In response to the command generated by the output voltage command generating section, the voltage converting section raises or lowers the output voltage of the direct-current power supply to a voltage indicated by the command and applies the voltage onto the rectangular wave inverter. This reduces a loss caused by a response delay of the electric motor.

摘要： An ignition timing control system for an internal combustion engine is associated with a fuel injection amount control system for calculating an amount of fuel to be supplied to the engine, based on operating conditions of the engine, correcting the calculated amount of fuel, based on an adherent amount of fuel adhering to the inner wall surface of the intake passage, and a carried-off amount of fuel to be carried off from the adherent fuel into each combustion chamber of the engine, and injecting the corrected fuel amount into the intake passage. The ignition timing control system comprises an ECU which detects whether the engine has been recovered from a fuel cut state to a fuel supply state, and calculates ignition timing of the engine, based on operating conditions of the engine detected by engine operating parameter sensors, including pressure within the intake passage. A retard amount by which the ignition timing is to be retarded is calculated based on the detected operating conditions of the engine when it is detected that the engine has been recovered from the fuel cut state to the fuel supply state. Further, the ignition timing is corrected based on the calculated retard amount.

摘要： An exhaust emission control device for an internal combustion engine is provided with a main catalyst activated with heat of exhaust gas, a self-exothermic type auxiliary catalyst activated with electric current energy and a silencer, which are connected in series and in sequence from an upstream side to a downstream side in an exhaust system leading from an engine body. Thus, noxious components included in the exhaust gas can be converted and the gas is purified by using the main and auxiliary catalysts in combination but with the auxiliary catalyst being subject to less heat from the exhaust gas than the main catalyst.
