摘要： An air-fuel ratio control system realized with a computer for an internal combustion engine is disclosed, wherein an idle discriminator unit discriminates whether the internal combustion engine is idle or not, and when it is idle, an idle air-fuel ratio compensation amount determining unit decides an air-fuel ratio compensation amount in accordance with an output of an air-fuel ratio detector. When the engine is not idle, on the other hand, a non-idle air-fuel ratio compensation amount determining unit decides an air-fuel ratio compensation amount. The idle air-fuel ratio compensation amount determining unit includes a rich-lean discriminator unit for discriminating whether the air-fuel ratio is on lean or rich side in accordance with the output of the idle discriminator unit, a skip unit for skipping the air-fuel ratio compensation amount to a greater degree than in non-idle state when the rich-lean discriminator unit decides that the air-fuel ratio has shifted from lean to rich side or the opposite way, a hold unit for holding the compensation amount after skip for a predetermined length of time, and an integrator for integrating the compensation amount upon the lapse of the predetermined length of time.

摘要： This apparatus measures and detects the air-flow taken into an intake pipe of an internal combustion engine, and includes an air-flow detecting sensor. The air-flow detecting sensor comprises a support frame made of heat-resistant insulation material, a heating line supported by the support frame on the upper side when viewed from the direction in which the air-flows, a heat-controlled heating current, and a resistance line also supported by the support frame on the lower side when viewed from the direction in which the air-flows which has a temperature characteristic. Air-flow detecting signals which represent the condition under which heat is transmitted to the resistance line through the air-flow are picked up from the sensor for every specified timing to set and calculate the transmitting coefficients of heat transmitted from the heating line to the resistance line, which is specified by the sensor and which is set corresponding to the amount of the signal detected by the sensor. The signal detected by the sensor is inversely transformed using the transmitting coefficients, and this transformed signal is supplied to the electronic control circuit of the internal combustion engine as part of the signal used for detecting the conditions under which the engine should be operated.

摘要： In an electronic digital control system for engine, a throttle position is sensed at predetermined time intervals to detect a variation thereof from the previous time to the present time, and, after modifying the detected variation by a correction coefficient related to a cooling water temperature to obtain the modified variation, the previous value of a fuel injection amount correction factor computed at the time of previous computation is added to the value of the modified variation to compute the sum. Then, a predetermined subtraction constant is subtracted from the sum to compute the difference therebetween, thereby obtaining the new data of the fuel injection amount correction factor, and this new factor is used to correct the basic fuel amount computed separately on the basis of the operating condition of the engine.
