    摘要: A control circuit for a fuel injection system used with internal combustion engines, of the type in which fuel injection valve control pulses are generated whose duration depends on engine data, in particular engine rpm and air flow rate. To avoid misfires when the engine is run fast with a closed throttle, the fuel supply is shut off by suppression of the fuel control pulses. For this purpose, the control circuit generates a reference rpm value and a reference pulse train of predetermined pulse duration and compares the duration of the actual fuel injection control pulses with the predetermined duration and, at the same time, it compares the actual rpm with the reference rpm. If the actual pulse duration is less than the reference duration and if the actual rpm is greater than the reference rpm, the control circuit suppresses the fuel injection control pulses.

    摘要: Equalization of a temperature distribution in a flow direction on a cooling plate is facilitated so that temperatures of plural cells that thermally contact with the cooling plate are equalized, to reduce variability in the state of charge-discharge and the lifetimes of the respective cells. A battery module includes a cooling plate having a refrigerant channel in which a refrigerant circulates, and plural cells that are thermally conductively coupled onto a surface of the cooling plate, in which the refrigerant channel is formed with plural large diameter pipes that decelerate the refrigerant, and plural small diameter pipes that accelerate the refrigerant, a channel sectional area of the large diameter pipes is larger than a refrigerant channel sectional area of the small diameter pipes arranged on an inflow side of the large diameter pipes.
