ABSTRACT:
An installation for preheating the suction or intake mixture of a carburetor internal combustion engine by means of an exhaust gas branch line branching off from an exhaust gas pipe system that is equipped with an exhaust gas manifold, and extending along parts of the suction pipe system in heat-exchanging relationship therewith, and which also includes a closure valve controlling the exhaust gas partial stream flowing through the branch line; a part of the exhaust gas pipe system is constructed as Venturi pipe of a gas jet pump and the exhaust gas branch line is connected downstream of the heat-exchange area with an annular space of the gas jet pump surrounding the Venturi pipe so that by the suction in the gas jet pump the branched-off exhaust gas partial stream is sucked back into the remaining exhaust gas stream, while the closure valve is arranged in the exhaust gas branch line.
