Swirl Control Valve (S.C.V.) Control

INPUT/OUTPUT SIGNAL LINE





SYSTEM DESCRIPTION
This system has a swirl control valve (S.C.V.) in the intake passage of each cylinder. While idling the S.C.V. closes. Thus the velocity of the air in the intake passage increases, promoting the vaporization of the fuel and producing a swirl in the combustion chamber. Because of this operation, this system tends to increase the burning speed of the gas mixture, improve fuel consumption, and increase the stability in running conditions. The solenoid valve controls S.C.V.'s shut/open condition. This solenoid valve is operated by the E.C.U.
