摘要： An air/fuel ratio control system is applicable to lean mixture combustion internal combustion engines. The control system determines the value of the mixture ratio at which engine stability can switch between stable and unstable conditions. As long as the engine continues to run in a stable condition in which the engine roughness is within an acceptable range, the mixture is intermittently leaned out by a given proportion. On the other hand, when engine roughness in an unacceptable range is detected, the mixture ratio is enriched by a given proportion to overcome the unacceptable engine roughness. Enrichment of the mixture is continued until engine roughness within the acceptable range is detected.

摘要： Normally, an air-fuel ratio is controlled in accordance with the engine speed and the intake air quantity of an internal combustion engine with a turbocharger. When the output pressure of the turbocharger increases excessively, an intake relief valve opens to decrease the intake air quantity. In this case, the fuel injection quantity is controlled solely in accordance with the engine speed.

摘要： A back-up system for an engine coolant temperature sensor detects deviation of the output of the temperature sensor from its designed output range to produce a fault signal. In response to the fault signal, an engine control system derives the engine coolant temperature indirectly from other engine conditions. This derivation is based on two facts: (1) the amount of fuel required to start the engine is related to engine temperature, and (2) since the calorific value of a given engine is essentially constant, the rate of increase of engine temperature is related to the integrated number of engine revolutions. Thus, when the engine is to be started, engine temperature can be derived by gradually increasing the fuel supply quantity from a minimal initial value until the engine is able to start to determine the required fuel supply quantity. Thereafter, the derived temperature value can be updated as a function of total engine revolutions.
摘要翻译：用于发动机冷却剂温度传感器的备用系统检测温度传感器的输出与其设计的输出范围的偏差，以产生故障信号。响应于故障信号，发动机控制系统从其他发动机状况间接地导出发动机冷却液温度。这个推导是基于两个事实：（1）起动发动机所需的燃料量与发动机温度有关，（2）由于给定发动机的发热量基本上是恒定的，发动机温度的增加率为与发动机整体转数有关。因此，当发动机起动时，可以通过从最小初始值逐渐增加燃料供给量直到发动机能够开始确定所需的燃料供给量来获得发动机温度。此后，导出的温度值可以作为总发动机转数的函数来更新。

摘要： In a method of supplying fuel to an internal combustion engine during start-up, the occurence of combustion is detected to arrest the change of the fuel supply quantity until steady-state engine operation is achieved. Combustion is detected by comparing sensed engine speed to a minimum engine speed resulting from combustion in the cylinders. Additionally, control values used to derive the start-up fuel quantity are modified so that the fuel quantity increases monotonically from a relatively low initial value until fuel ignition is detected.

The system comprises a fuel supply member for supplying fuel to each cylinder of the engine; a pressure sensor which outputs a signal representative of an internal pressure of each cylinder under compression stroke; a crankangle sensor which outputs two types of signals, one being a signal which is issued each time a crankshaft of the engine rotates by a given angle, and the other being a signal which is issued each time the crankshaft comes to a given angular position; a pre-ignition judging device for judging whether a pre-ignition occurs or not in each cylinder based on the signals from the pressure sensor and the crankangle sensor; and a fuel supply stop device for stopping the fuel supply to a cylinder when the pre-ignition judging device judges that the cylinder encounters the pre-ignition.

摘要： An air fuel ratio control system includes a correction system for correcting air/fuel ratio depending on measured atmospheric air pressure. The correction system has sensors for detecting engine operating conditions. A reference intake manifold pressure corresponding to the detected engine operating condition at sea level is obtained from the engine operating condition. The reference atmospheric air pressure is compared with the measure intake manifold absolute pressure to determine a difference value. Based on the difference, a correction value for controlling the air/fuel ratio is determined.
