Abstract:
[Problem] To provide an automobile engine capable of converting vapor energy of vaporized atomized water, together with combustion energy of hydrogen gas, into motive power of the engine. [Solution] An automobile engine 10 is provided with a hydrogen gas nozzle 32 for directly injecting hydrogen gas into a combustion chamber 37 of a cylinder 36, and a mist nozzle 38 for feeding mist-like atomized water into the combustion chamber 37, wherein a compression ratio of the engine lies in a range of 14:1 to 15:1. In the automobile engine 10, hydrogen gas is fed into the combustion chamber 37 from the hydrogen gas nozzle 32, and mist-like atomized water is fed into the combustion chamber 37 from the mist nozzle 38, the hydrogen gas in the combustion chamber 37, which has been compressed to a predetermined compression ratio by means of a piston 39, is ignited by means of an ignition plug 40, the mist-like atomized water is vaporized by the heat of combustion of the hydrogen gas while the hydrogen gas nozzle is burned, and the combustion energy of the hydrogen gas and the vapor energy of the vaporized atomized water are converted into motive power.
