    • A tongue assembly for use in a seat belt device is formed of a tongue main body engaging a buckle and a slider slidably disposed over the main body. A first slit is situated in a middle portion of the main body to extend in a direction perpendicular to an inserting direction of the main body relative to the buckle. A first wall portion is fixed to the main body to project upwardly from an upper surface of the main body along the first slit at a side of a rear portion. A second wall portion is formed in an upper side of the slider and has a surface opposing to the first wall portion. A second slit is formed at a lower side of the slider so that a rear edge of the second slit at a side of a rear portion of the main body is situated close to an insertion portion of the main body with respect to the surface of the second wall. A third slit is further formed in the rear portion of the main body. A seat belt extends between the first and second wall portions, through the first and second slits, under the lower side of the slider and through the third slit so that when a tension is applied from the side of the third slit, the slider is pulled toward the rear portion of the main body to urge the second wall portion of the slider to the first wall portion to thereby strongly hold the seat belt between the first and second wall portions.

    • A fuel injection detecting system is used with a diesel engine having a fuel injection nozzle, the nozzle including a movable member for effecting fuel injection into the engine when the valve member is displaced from its normal position and interrupting fuel injection when the valve member is returned to its normal position. The detecting system includes a sensor for sensing displacement of the valve member and generating a signal indicative thereof. A comparator is provided to compare the signal from the sensor with a reference signal and to generate a signal indicative of fuel injection via the nozzle. The detecting system also includes a device for preventing the fuel injection signal from including components unrelated to fuel injection via the nozzle. This device may disable the sensor for a predetermined period immediately after the first major displacement of the valve member. Alternatively, the device may adjust the reference voltage so as to hold the voltage thereof at a level exceeding that of all features of the sensor signal except the signal largest peak during each fuel injection.

    • A system and method for controlling an ignition timing in an internal combustion engine which controls the ignition timing by correcting the ignition timing by a retardation angle for avoiding the occurrence of the knocking when the level of knocking exceeds a predetermined angle and/or by correcting the ignition timing (MBT control) by a correction value on the basis of an crank angle at which the combustion chamber pressure has reached its maximum. When the engine is not in a transient operating state, the system stores the correction value of the ignition timing during knocking avoidance control or during MBT control as a learning value corresponding to the engine operating condition and calculates the actual ignition timing on the basis of the learning value and basic ignition timing determined by the engine operating condition. When the engine is in the transient operating state, the MBT control is not carried out. Therefore, such an undesirable state occurs that the correction value of the ignition timing is varied to a large degree when the engine operating state is changed, thus torque variation results, and inaccurate ignition timing control is not carried out. In addition, since the history of retardation angle correction by means of the past knocking avoidance control reflects the present calculation of ignition timing angle value, a preventive control of the occurrence of knocking is achieved. Consequently, a driving range in which the MBT control becomes effective is extended so that the engine output power can be improved.
    • 一种用于控制内燃机中的点火正时的系统和方法,其通过将点火正时校正为相位角来控制点火正时,以在爆震水平超过预定角度时避免爆震的发生,和/或通过校正 基于燃烧室压力达到其最大值的曲轴角度的校正值来确定点火正时(MBT控制)。 当发动机不处于暂态运行状态时,系统将起爆回避控制期间的点火正时的校正值或在MBT控制期间存储为对应于发动机运转状态的学习值,并基于 由发动机工作条件确定的学习值和基本点火正时。 当发动机处于瞬态运行状态时,不执行MBT控制。 因此,当发动机运转状态发生变化时,点火正时的修正值发生很大变化,不能实现转矩变动,不能进行不准确的点火正时控制,所以出现这种不良状态。 此外,由于通过过去的敲击避免控制的延迟角校正的历史反映了当前点火正时角度值的计算,因此实现了敲击发生的预防性控制。 因此,延长了MBT控制有效的驱动范围,能够提高发动机的输出功率。

    • A device for determining a crank shaft angular position performs operation for determining the crank shaft angular position at an occurrence of timing control in an internal combustion engine control, such as fuel injection timing control, spark ignition timing control and so forth. In determination of the crank shaft angular position, an angular acceleration is firstly calculated with respect to respective intervals of crank reference angle signals. In calculation, the determined angular acceleration is regarded as constant instead of an angular velocity. At the same time, time intervals between respectively adjacent crank reference signals and between one of crank reference signal and a timing control signal immediately following to the one of crank reference angle signal are measured. Based on the determined angular acceleration and the time interval between the one of crank reference angle signal and the timing control signal, the crank shaft angular position at the occurrence of the timing control signal is determined. This may provide determination of the crank shaft angular position precisely following to the actual crank shaft angular position even when the engine revolutional fluctuation is significant.
    • 用于确定曲柄轴角位置的装置执行在内燃机控制中的定时控制发生时确定曲柄轴角位置的操作,例如燃料喷射正时控制,火花点火正时控制等。 在确定曲柄轴角度位置时,首先根据曲柄参考角度信号的各个间隔计算角加速度。 在计算中,所确定的角加速度被认为是恒定的而不是角速度。 同时,测量相应的曲柄参考信号之间和曲柄参考信号之一之间的时间间隔和紧跟在曲柄参考角度信号之后的定时控制信号。 基于确定的角加速度和曲柄参考角度信号与定时控制信号之间的时间间隔,确定出现定时控制信号时的曲轴角位置。 即使当发动机转动波动很大时,也可以精确地跟随实际的曲柄轴角度位置来确定曲轴角度位置。

    • An exhaust gas recirculation method and apparatus controls the duty cycles of a throttle valve provided in an air intake passageway leading to a diesel engine, and an exhaust gas recirculation valve provided in an exhaust gas recirculation passageway connecting the air intake passageway and an exhaust gas passage, according to a predetermined relationship. The respective valves are controlled via corresponding diaphragm actuators and electromagnetic valves for actuating the actuators by a control unit which produces duty cycle control signals for the respective electromagnetic valves in accordance with sensed operating parameter signals which represent engine speed, load and coolant temperature. The control of the throttle and EGR valves are related so that the throttle valve is held fully open when the EGR valve is not fully open. This ensures the absolute minimum emission of exhaust HC throughout the range of throttle-EGR control.
