Abstract: In a diesel engine having a rotational angle sensor for detecting the engine speed, when the rotational angle sensor is in an abnormal state, a fuel-cutting operation is performed. A first fuel-cutting operation is immediately performed so as to indicate to the driver that an abnormal state exists. However, subsequent fuel-cutting operations after restarting of the engine are delayed as compared with the first fuel-cutting operation.

Abstract: An air-fuel ratio compensating apparatus for the carburetor of an internal combustion engine has first and second valves having equal control (input) current-opening characteristics and provided in main and slow system air bleed paths respectively to control sectional area of flow in the main and slow system air bleed paths in relation to the output of an air-fuel ratio sensor, electronic control circuit which sends the control current to the first and second valves in such a way that the opening of the second valve is always larger than that of the first valve. Thus, flow of the main system air bleed is restrained during the initial part of the acceleration period so as to reduce the amount of noxious component in the exhaust gas.

Abstract: A fluid control valve assembly for controlling the flow of fluid passing through a fluid passageway defined in a valve body and having an inlet end and an outlet end. A bellows formed of low tackiness material has fixed one end wall secured to the valve body and the other movable end wall connected to a valve stem. The valve stem is actuated by an actuator to move the other movable end wall of the bellows between a closed position in which the other movable end wall is brought into direct contact with a valve seat located in the fluid passageway and an open position in which the other movable end wall is brought out of engagement with the valve seat.
