摘要： Disclosed in an intake pipe pressure detecting device for detecting the pressure in that section of an intake pipe in an internal combustion engine which is on the downstream side of a throttle valve provided in the intake manifold. The pressure detecting device comprises a mixing chamber which has an opening in the wall of the intake pipe, a pressure introducing path which opens onto this mixing chamber, and air inlets adapted to allow fresh air to enter the mixing chamber, thereby generating an air flow directed from the mixing chamber to the intake pipe.

摘要： For controlling a pulse-operated electromagnetic valve, an energization voltage is applied to the actuating coil of the valve in response to a leading edge of the pulse to initiate an energization current. When the current reaches a predetermined peak value the voltage is decoupled from the coil to allow a circulating current to flow through a first path to decrease it at a higher rate. The circulating current is switched to a second path when it reaches a medium current value to decrease it at a lower rate. When the decreasing circulating current reaches a lower holding current value which is necessary to hold the valve operated, the voltage is coupled again to the coil to reinitiate the energization current, and when it reaches a higher holding current value lower than the medium current value the voltage is decoupled to reinitiate the circulating current. The higher and lower holding current values are successively detected to energize the coil with a current which is an average value of the higher and lower current values.
