ABSTRACT:
In an engine using fuel of low startability, there are provided an ultrasc atomizer and a fuel injection valve arranged on a suction pipe of the engine, and a catalyzer unit mounted between said ultrasonic atomizer and a fuel injection valve. When the engine is started, the fuel atomized by the ultrasonic atomizer is supplied to the catalyzer unit to generate an intermediate product of high volatility. After the engine has been started, fuel is supplied through the fuel injection valve. When a fuel is passed through the catalyzer unit such as methanol fuel, aldehyde is generated by a decomposition reaction, reforming reaction, partial oxidation reaction, etc., or dimethylether is generated by a dehydrating condensation reaction. By supplying this intermediate product of high volatility to the engine, the startability of the engine at low temperatures is improved.
