Abstract
An arrangement is disclosed for heating the suction gases of an internal combustion engine by utilizing the exhaust gases from the engine in order to promote the vaporization of the fuel contained within the suction gases while the engine is still in a cool state. In the arrangement, the high temperature exhaust gases from the engine are routed, by the control of a control valve rotatable between two positions in the exhaust manifold, around fins formed on the exterior wall of the bottom floor of the intake manifold for receiving the heat of the exhaust gases, and a covering is provided for enclosing the fins in a closed chamber. The covering, made of a heat resistant metal plate, is provided with inlet and outlet ports so as to introduce the exhaust gases into the chamber and drain the exhaust gases from the chamber. The covering is further provided with a vertical wall or walls which descend therefrom into the exhaust manifold so that the control valve comes into close contact with walls when the control valve is rotated to the two positions, respectively, in the exhaust manifold.
