<p>PURPOSE:To raise the mixing of mixed gas and exhaust gas as well as accelerate the atomizing of mixed gas by introducing exhaust gas to be recirculated to suction pipe to the axial direction of suction path through a throttle. CONSTITUTION:The suction manifold provided with the cooling water path 5 is connected to the lower part of the suction path 1 with the throttle 2, and also the inside of the manifold 4 is provided with the inner cylinder 8 hanging from the suction path 1 and the outer cylinder 9 situated on the periphery of the cylinder 8. And the EGR pipe 12 is connected to the annular space 10 between both the cylinders 8 and 9, and the narrow contract space 13 is formed at the lower part the cylinders and the lower part 14 of the outer cylinder is made longer. Thus, exhaust gas introduced into the annular space 10 is made its flow rate faster and then injected into the manifold 4.</p> |
