PURPOSE:To significantly reduce the harmful components in exhaust gas by arranging a fuel supply device in the intake-air passage of an engine, and also by providing a semiconductor ceramics heater of a multihole flow-passage construction on the downstream side of the fuel supply device. CONSTITUTION:A fuel supply device 5 is arranged in the intake-air passage 4 of an engine 1. On the downstream side of this fuel supply device 5, a semiconductor ceramics heater 13 of multihole flow-passage construction is provided. When the engine is started, the semiconductor ceramics heater 13 is electrified. In the process atomized fuel liquid drops pass through the flow passage of the multihole ceramics heated by the semiconductor ceramics heater 13, vaporization and activation thereof is accelerated by heat exchanging action. Thus, by improving the startability of a spark ignition type internal combustion engine, harmful components in the exhaust can be significantly reduced.
