摘要： An air-fuel ratio control system for an internal combustion engine includes an ECU which cuts off fuel supply to the engine at deceleration thereof, measures a fuel cut-off period over which the fuel cut-off means cuts off fuel supply to the engine, and enriches the air-fuel ratio of a mixture supplied to the engine to a degree dependent upon the measured fuel cut-off period, at the restart of fuel supply to the engine immediately after termination of cutting-off of fuel supply to the engine. When a second cutting-off of fuel supply to the engine is carried out within a predetermined time period after the restart of fuel supply to the engine immediately after termination of a first cutting-off of fuel supply to the engine, the ECU sets the degree of enriching the air-fuel ratio of the mixture supplied to the engine according to the sum of a first fuel cut-off period over which the first cutting-off of fuel supply to the engine lasted and a second fuel cut-off period over which the second cutting-off of fuel supply to the engine lasted.

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 system for detecting failure of a fuel pressure sensor in an internal combustion engine, including an injector (32) provided at an intake system of the engine downstream of a throttle valve (38), a fuel supply passage (16) connected to a fuel supply source (fuel tank 12) for supplying fuel to the injector (32), pressure regulator (28) provided in the fuel supply passage (16) and operating to maintain a difference between the fuel pressure (PF2A) and the manifold absolute pressure at a constant value, a fuel pressure sensor (PF2 sensor 54) for detecting the fuel pressure (PF2A) in the fuel supply passage (16) downstream of the pressure regulator, and a manifold absolute pressure sensor (62) for detecting the manifold absolute pressure (PBA) downstream of the throttle valve (38). In the system, an index indicative of a ratio (.DELTA.PF2A) of the fuel pressure (PF2A) fluctuation relative to the manifold absolute pressure (PBA) fluctuation is compared to reference values (#PF2L, #PF2H) which define a range. Sensor failure is discriminated when the index (.DELTA.PF2A) is found to have remained outside of the range for a predetermined maximum time (tmP2STK). The system enables rapid and accurate detection of fuel pressure sensor abnormality (failure).

摘要： A catalyst deterioration-determining system for an internal combustion engine has a catalyst arranged in the exhaust system, for purifying exhaust gases emitted from the engine, an oxygen concentration sensor arranged in the exhaust system at a location downstream of the catalyst, for detecting the concentration of oxygen present in the exhaust gases, and an ECU which controls the air-fuel ratio of an air-fuel mixture supplied to the engine in a feedback manner in response to the output from the oxygen concentration sensor. Determination of deterioration of the catalyst is carried out based on the output from the oxygen concentration sensor during execution of air-fuel ratio feedback control. An inversion period parameter representative of a repetition period of change in the output from the oxygen concentration sensor over a predetermined diagnosis period is measured, and a determination parameter is calculated by averaging values of the inversion period parameter measured over different diagnosis periods as the predetermined diagnosis period. The determination of deterioration of the catalyst is carried out based on the determination parameter.

摘要： In a fuel vapor release suppression system for a fuel tank, a main tank and a sub tank communicate with each other, and the sub tank and a canister communicate with each other. When the main tank has a higher temperature, fuel vapor of the main tank is supplied to the sub tank where the fuel vapor is liquefied. When the main tank has a lower temperature, fuel vapor of the sub tank is supplied to the main tank. At this time, low concentration fuel vapor is supplied from the canister to the main tank, thereby accelerating generation of fuel vapor corresponding to sub tank fuel vapor pressure, so that the sub tank fuel vapor pressure decreases. Therefore, liquefaction is accelerated in the sub tank when the main tank temperature increases. Thus, fuel vapor generated in a fuel tank is effectively liquified irrespective of ambient air temperature.
