摘要： A system and method for controlling an ignition timing for an internal combustion engine mounted in a vehicle are disclosed in which a limit value for the ignition timing value is provided so that a difference between a current ignition timing and a previous ignition timing is within the limit value and the limit value is set according to a magnitude of an engine acceleration. For example, when an abrupt engine acceleration occurs, the limit value is set to 15 degrees. When the engine is in a steady state (no abrupt acceleration from an idling condition), the limit value is set to four degrees. Therefore, no vehicle body shock occurs due to the abrupt change in an engine output torque caused by the abrupt change in the ignition timing and a response characteristic of a rise in the engine output torque during the abrupt acceleration can be assured.
摘要翻译：公开了一种用于控制安装在车辆中的内燃机的点火正时的系统和方法，其中提供了点火正时值的极限值，使得当前点火正时与先前点火正时之间的差值在极限内值，并且根据发动机加速度的大小设定极限值。例如，当发生急剧的发动机加速时，将极限值设定为15度。当发动机处于稳定状态（没有从怠速状态突然加速）时，极限值设定为4度。因此，由于点火正时突然变化引起的发动机输出转矩突然变化，并且可以确保突发加速期间的发动机输出转矩的上升的响应特性，所以不会发生车身冲击。

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 motor driving circuit includes a three-phase inverter circuit 8, including three upper-arm switching elements 56a to 56c for driving upper arms of different phases of a three-phase motor 3, and three lower-arm switching elements 56d to 56f for driving lower arms of different phases. At least one of the upper-arm switching elements 56a to 56c and the lower-arm switching elements 56d to 56f is a semiconductor element that performs a diode operation. The diode operation is an operation in which a voltage less than or equal to a threshold voltage of a gate electrode G is applied to the gate electrode G with reference to a potential of a first ohmic electrode S, thereby conducting a current flow from the first ohmic electrode S to a second ohmic electrode D and blocking a current flow from the second ohmic electrode D to the first ohmic electrode S.

摘要： A bidirectional switch comprises a first FET, a second FET, and a switch controller for controlling a conductive state in which current from a bidirectional power supply electrically connected to drain terminals bidirectionally flows, and a nonconductive state in which the current does not flow. In the conductive state, the switch controller applies, to gate terminals of the first FET and the second FET, a voltage higher than a threshold voltage with reference to a potential at a node to which source terminals of the first FET and the second FET are connected. In the nonconductive state, the switch controller causes the bidirectional power supply and each gate terminal to be electrically insulated from each other, and applies a voltage lower than or equal to the threshold voltage with reference to the potential at the node.

摘要： Reduction of noise is achieved by devising an arrangement of heat generating parts such as a light bulb element, an electric power source, a light source, etc. and an arrangement of cooling fans. In cooling the light source, the electric power source and liquid crystal panels, a cooling wind path for the liquid crystal panels and the electric power source is made separate from and independent of a cooling wind path for the light source that generates much heat, a cooling air volume is optimized for the respective cooling wind paths, and noise accompanying the rotation of the cooling fans is reduced. Also, by arranging the cooling fans substantially centrally of the respective cooling wind paths, that volume of noise, which leaks from air intake ports and air exhaust port that are opened to a housing of a unit, is reduced.
