摘要： In a fuel injection control system for an internal combustion engine, operating conditions of the engine are constantly monitored. A transient condition of the engine is detected from the monitored operating conditions. A fuel injection quantity is derived from the monitored operating conditions to effect injection at first intervals during the absence of the transient condition and at second intervals during the presence of the transient condition. Fuel injectors are activated in response to the derived fuel injection quantity.

摘要： An apparatus for controlling an air-fuel ratio in internal combustion engines has an RPM sensor, a combustion composition sensor, an intake air sensor and so on. Detection signals from these sensors are fetched by a microprocessor. A RAM is arranged in the microprocessor and is continuously supplied with power. The RAM has a first memory area which is divided into a plurality of areas for storing correction data corresponding to operating states of the engine. All the correction data stored in the first memory area are added together and the sum is divided by a given constant so as to obtain an updated correction amount. This updated correction amount is stored in a second memory area. The updated correction amount in the second memory area reflects the correction data stored in the first memory area. Given correction data stored in the first memory area is read out corresponding to a given intake air flow, thereby enabling feedback control.

摘要： In an engine-motor hybrid vehicle, vehicle drive regions are divided into a plurality of groups specified by a plurality of operation state variables. A learning variable set for each drive region is updated according to an amount of a power state of an engine, when the vehicle is in a steady state running. The learning variable indicates a change in the power state amount with age. When an engine power demand value is determined, it is corrected by using the learning variable of a selected drive region to calculate a corrected engine power demand value compensating a change in the engine with age. In this manner, the engine power is controlled.

摘要： In a closed loop control system for air/fuel ratio control of an internal combustion engine, an integration correction factor is derived from the output signal of a gas sensor indicative of the concentration of an exhaust gas component, and an engine condition correction factor is selected from a memory in which a plurality of engine condition correction factors are prestored in the form of a table. The engine condition correction factor is renewed in accordance with the variation in the value of the integration correction factor so as to perform learning control. In order to prevent each of the engine condition correction factors from assuming an undesirable value which are far deviated from its standard, a constant or variable limit value is set. The limit value may be set by calculating some typical engine condition correction factors. The correction factors will be used to modify a basic quantity of fuel to be injected into each cylinder of the engine for feedback controlling the air/fuel ratio of the air/fuel mixture.

摘要： An air-fuel ratio control system for an internal combustion engine includes an air-fuel ratio sensor provided at a collecting portion of an exhaust manifold. The air-fuel ratio sensor monitors an exhaust gas and changes its output in a linear fashion relative to an air-fuel ratio represented by the exhaust gas. The air-fuel ratio sensor is arranged at a position such that, after the number of strokes, corresponding to a multiple of the number of all cylinders, from a fuel injection for each cylinder, the air-fuel ratio sensor can measure an air-fuel ratio caused by the corresponding fuel injection. The system stores a target fuel amount for each of the cylinders. The system derives a feedback correction value depending on a deviation between a fuel amount introduced into the corresponding cylinder, which is derived based on the air-fuel ratio monitored by the air-fuel ratio sensor, and the stored number-of-stroke prior target fuel amount.

摘要： A deterioration monitoring apparatus for an exhaust system of an internal combustion engine includes an air-fuel ratio control system and a deterioration determining circuit. The air-fuel ratio control system controls an air-fuel ratio of exhaust emissions flowing downstream of a catalytic converter disposed in the exhaust system of the engine to agree with a target downstream air-fuel ratio under feedback control based on an air-fuel ratio of exhaust emissions flowing upstream of the catalytic converter and the air-fuel ratio of the exhaust emissions flowing downstream of the catalytic converter. The deterioration determining circuit determines whether the exhaust system such as an oxygen sensor mounted downstream of the catalytic converter or the catalytic converter is deteriorated or not based on the air-fuel ratio of the exhaust emissions flowing downstream of the catalytic converter and the target downstream air-fuel ratio.

摘要： To provide a water temperature sensor failure detecting device for an idle speed control system of an internal combustion engine which eliminates the need for a bimetallic guard mechanism, an aperture characteristic of an idle control valve (ISCV) when normal becomes a larger degree of opening as coolant water temperature drops, and bypass airflow supplied to an engine is increased. During failure of a water temperature sensor, a duty value for driving the ISCV is set at 50%, the ISCV is opened substantially halfway, and the bypass airflow supplied to the engine is caused to be a neutral flow. In this way, by causing the bypass airflow during failure of the water temperature sensor to be a neutral flow, a worst state of overrun, engine stall and the like can be prevented, and startability when at low temperature and operability after engine warmup can be ensured.
