Hydrogen, after being released from the hydrogen high pressure tank, passes through the first solenoid
valve, the second solenoid valve, the gas lock (operated by the negative pressure in the engine) and the
vaporizer, and is finally injected into the cylinder. Air goes through the air cleaner and the carburetor, then
into the engine at the end. Air mass flow is controlled by the accelerator. Water is changed into fog water
in the water injection device and then is directly injected into the cylinder. At present, approximately 55%
of the world's total production of oil is consumed as power fuel.
Considering this fact, the use of hydrogen energy has a great environmental significance,and that's where
our HAW system makes a revolutionary energy contribution for not only today's world but also the future
- generations to come.
The greatest feature of our hydrogen-fuel engines lies in the structure of its system wherein a gas
internal-combustion engine system and a steam engine system are combined, Hydrogen is burned in the
engine cylinder, and the temperature obtained from the combustion is used instantaneously to vaporize
the water which is injected into the cylinder through another system route: thus,the explosively expanded
energy obtained from vaporization is convered into motion energy.

In general, as for the hydrogen internal combustion engines, a backfire and knocking occur easily, thus it is natural to associate the name of the hydrogen internal combustion engines with a backfire and knocking.

A HAW-SYSTEM hydrogen fuel-vehicle cleared the backfire and prevented the outbreak of the knocking technically. The backfire and the knocking did not occur at all and the output performance materialized as more than 1.5 times of the gasoline car’s output performance.

The HAW-SYSTEM hydrogen vehicle can run the same mileage with hydrogen 2m³ instead of using gasoline 1 ℓ. The output of the hydrogen car makes the hydrogen car run efficiently by restraining from over 1.5 times of the gasoline car’s output to 1.2 times of that, and the mileage efficiency is superior to a fuel cell-powered vehicle.
