Abstract

PURPOSE: To improve activity of a catalyst of an exhaust system containing rhodium and highten the exhaust cleaning efficiency.
CONSTITUTION: An unillustrated engine exhaust passage is provided with an exhaust cleaning device of ternary catalyst system containing rhodium requiring a comparatively long time for warmup as catalyst noble metal. An unillustrated intake system of said engine is supplied with fuel through the main jet 3. Jet 3 is supplied with gasoline fuel from a float chamber 1 exclusively for gasoline through a fuel passage 2 followed by fuel supply from the float chamber 5, which is filled with methyltertiary butylether or with the fuel consisting of the above the gasoline and having good combustibility at low temperature, through an auxiliary fuel passage 2A. Further at the branching part a switching valve 4, which opens the auxiliary passsage 2A under the fixed catalyst temperature.
