摘要： A period of from when the starter switch is turned on or from the start of the fuel injection until when the engine rotation speed has reached a predetermined rotation speed, is detected as a parameter representing the starting performance. After the engine rotation speed has reached a predetermined rotation speed, furthermore, the parameter representing a change in the rotation and the parameter representing rising gradient of the rotation-speed are detected. Then, the parameter representing the starting performance, the parameter representing a change in the rotation and the parameter representing a rising gradient of the rotation speed are weighted to detect the fuel property.

摘要： A diagnostic system for detecting a freezing condition of an intake pressure sensor for an engine includes a control unit for checking engine operating parameters after a turn-on of an ignition switch to determining whether the engine is a predetermined state permitting a freeze diagnosis, and for performing the freeze diagnosis only when the engine is in the predetermined state. The control unit monitors a decrease of the intake pressure sensed by the intake pressure sensor as the engine speed increases from a start, and judges a freezing condition to exist if the intake pressure does not become sufficiently low even after the engine speed becomes higher than a predetermined speed level.

摘要： An object of the present invention is to be able to correct for deviation of an actual air-fuel ratio from a point for satisfactory purification performance of an exhaust gas purification catalytic converter, during an interval from immediately after start up until an air-fuel ratio sensor and an exhaust gas purification catalytic converter attain a stable condition. To achieve this, a control constant in an air-fuel ratio feedback control is set and altered during an interval from immediately after start up until the air-fuel ratio sensor and the exhaust gas purification catalytic converter attain a stable condition. In this way, the actual air-fuel ratio can be shifted, and hence the deviation of the actual air-fuel ratio from the point for satisfactory purification performance of the exhaust gas purification catalytic converter during the interval from immediately after start up until the air-fuel ratio sensor and the exhaust gas purification catalytic converter attain a stable condition, can be corrected. Consequently, the situation immediately after start up where the actual air-fuel ratio deviates from the target air-fuel ratio, attributable to the air-fuel ratio sensor and the exhaust gas purification catalytic converter being in an unstable condition, can be suppressed. Therefore the purification efficiency of the exhaust gas purification catalytic converter can be kept high.
摘要翻译：本发明的目的是能够在从启动之后的间隔到空燃比的间隔期间校正实际空燃比与排气净化催化转化器的令人满意的净化性能的点的偏差传感器和排气净化催化转化器达到稳定的条件。为此，空燃比反馈控制中的控制常数在启动后直到空燃比传感器和废气净化催化转换器达到稳定状态的间隔内被设定和改变。以这种方式，实际的空燃比可以偏移，因此实际的空燃比与排气净化催化转化器的净化性能令人满意的点之间的距离从启动之后到空气 - 燃料比传感器和排气净化催化转化器达到稳定的条件，可以纠正。因此，可以抑制由于空燃比传感器和排气净化催化剂处于不稳定状态而导致的实际空燃比偏离目标空燃比的起动之后的状态。因此，废气净化催化转化器的净化效率可以保持较高。

摘要： A reference angle signal which provides a reference for ignition control of each cylinder is output together with a cylinder discrimination signal for matching the reference angle signal with the respective cylinder, and ignition control carried out for separate cylinders on the basis of the cylinder discrimination results from the cylinder discrimination signal. When there is an abnormality in the cylinder discrimination signal and cylinder judgment becomes nonfunctional, the reference angle signal is matched with the respective cylinder in the ignition order under the normal conditions up until the occurrence of the abnormality, and ignition is carried out normally in the separate cylinders. As a result, even if cylinder discrimination by the cylinder discrimination signal becomes nonfunctional, ignition for separate cylinders can be continued, so that the engine can keep running.
