  • Publication number: 20130013173
    Abstract: An engine includes a normal fuel tank, fuel gas tank, an in-tank injection valve and a fuel gas supply valve. During operation of the engine, in a state where the fuel gas supply valve is closed, a fuel is injected into the fuel gas tank through the in-tank injection valve to generate a fuel gas by vaporizing the fuel. The fuel gas is stored in the fuel gas tank and is maintained in the gas phase due to the natural decompression even after the engine is stopped. To start the engine, the fuel gas supply valve is opened to supply the fuel gas in the fuel gas tank to a surge tank. Thus, compared with the case where the fuel gas is generated at the start of the engine, the fuel gas can be quickly supplied into the cylinder, so that the ability to start the engine is improved.
