Generally, Hydrogen-fueled internal combustion engine causes "Backfire" and "Knocking" quite often, so to say, those two words above have become synonyms for Hydrogen-fueled internal combustion engine disgracefully.

However, our newly developed hydrogen vehicle equipped the hydrogen-fueled internal combustion engine operated by H.A.W.-SystemTM; NEVER CAUSES those headaches above, because H.A.W.- System™ sweeps concern away with the innovative technology. The output performance of H.A.W.- System™; car achieved 1.5 times or more than that of a conventional petrol car. H.A.W.- System™ car runs with 2m3 of hydrogen gas, which consumes 5,000 kcal equal to the mileage that conventional gasoline-fueled car runs with 1 liter of gasoline, which consumes 8,500 kcal. This fact proves that H.A.W.- System™ car has superb performance and excellent fuel efficiency.

Fundamental Features

• Retrofit the fuel-supply system of conventional engines. (ref. H2 car brochure)
• Operated by the internal combustion engine, which burns hydrogen directly. (completely different from FCV)
• Convert water into superheat steam with the combustion heat (1200-1600°C) of hydrogen gas.
• Obtain kinetic energy pushing piston up & down with explosive thermal energy of hydrogen gas and steam energy.
  

　The volume of hydrogen expands to 1660 times as big as itself when water becomes superheated vapor.

《We obtained the patents of this invention from 35 countries including Japan, the U.S., Canada, as the world first invention in this field. 》

The fundamental key of H.A.W. System™ engine is to formulate the system combining the internal-combustion engine and the steam engine. That it to say hydrogen burns in a cylinder, then the combustion heat vaporizes water instantly. The explosive thermal energy obtained by evaporation as mentioned above, converts to kinetic energy.
