Abstract
An intake system for an internal combustion engine comprises an intake pipe structure connected through an intake manifold to cylinders of the engine, a fuel injection valve for injecting fuel into the intake pipe structure to form an air-fuel mixture, a throttle valve disposed in the intake pipe structure, and a baffle plate disposed in the intake pipe structure between the fuel injection valve and the throttle valve for promoting fuel atomization. The baffle plate has a surface which faces the fuel injection valve with a predetermined distance from the latter in order that the fuel injected from the fuel injection valve may impinge on the surface, and an outer edge spaced from an inner wall surface of the intake pipe structure to define a mixture passage therebetween. The baffle plate is made of a ceramic material having positive resistance-temperature characteristic and definite Curie point and adapted to be heated when electric current is applied thereto, so that it may be maintained at a temperature appropriate to cause preferable atomization of the fuel impinged on the baffle plate surface.
