An engine (internal combustion engine) that uses hydrogen as fuel. Its basic structure is the same as gasoline and diesel engines, but unlike gasoline engines, it does not require a carburetor. Currently, with very few exceptions, all engine fuels are petroleum products, and as demand for hydrogen increases in the future and petroleum reserves decrease, there will naturally be a shortage of fuel. At the same time, the damage caused by air pollution from combustion gases is also a major problem. In contrast, hydrogen can be produced from any energy source, including coal and natural gas, as well as atomic, solar, and wave energy, and it is also possible to make it non-polluting, so many researchers are conducting research into the most efficient, safe, and easy-to-use hydrogen engines.

水素を燃料とするエンジン(内燃機関)。ガソリンエンジンやディーゼルエンジンと基本的構造は変わらないが,ガソリンエンジンと異なり,気化器は必要ない。現在,エンジンの燃料はごく例外を除きすべて石油製品であり,将来その需要量が拡大するとともに,石油の埋蔵量が減少すれば当然不足をきたし,また,一方では燃焼ガスによる大気汚染の被害も大きな問題となっている。これに対して,水素は石炭や天然ガスはもちろん,原子力や太陽,波動などあらゆるエネルギー源からつくることができ,かつ無公害化も可能であることから,多くの研究者によって,もっとも効率がよく安全で取扱いの容易な水素エンジンを目的とした研究が行われている。
