PURPOSE:To provide smooth deceleration by furnishing a shut-off valve on the undestream of suction passage about a fuel supply device, shutting this valve at the time of deceleration, and thereby preventing inhalation of the facial stream on the wall. CONSTITUTION:A partition member (shut-off valve) 15 is installed on the downstream of a fuel supply device 13 furnished in the suction passage 12 of an engine 11. When a control circuit 28 senses the decelerative condition, this shut- off valve is closed. This will hinder the facial stream A during deceleration from being inhaled into the combustion chamber to provide smooth deceleration. |
