The hydrogen made by GOC employs the high-tech solid oxide proton exchange membrane that produces hydrogen by electrolysis of pure water, so the impurity analysis shows merely trace oxygen and aqua. The hydrogen purity more than 99.999% is estimated due to the dew-point value under -66 degrees Celsius (-5ppm) and the oxygen value under 5ppm processed by the HGL purifier in charge of filtration and purification.

In theory, fuel under perfect combustion in the automotive engine exerts only steam and carbon dioxide, but fuel under imperfect combustion of high temperature certainly exerts some pollutants such as carbon oxide, hydrocarbon and nitrogen oxides. The ingredients of grease products (such as lubricant and petroleum) and high-temperature combustion make petroleum form the paint-like colloid on the nozzle and the intake valve since grease products have soluble and insoluble colloid ingredients where the former deposit on the nozzles, the intake valve and the intake manifold and the latter sediment in the fuel tank.
Automobile engine carbon buildup generally results from the 2 causes as follows. First, carbon buildup caused by petroleum coke due to part imperfect combustion for fusion of high temperatures under combustion of the combustion chamber and low temperatures of the cylinder wall. Second, automobile combustion occurs by inducting the crankcase oil gas to the intake manifold, but the major oil gas in the crankcase pertaining to the steam of engine oil with high viscosity that attaches to the intake manifold and enters the combustion chamber leads to carbon buildup as well.

Engine carbon buildup is caused by various factors such as grease products, engine design and driving habits for a long time. The impacts of carbon buildup on your car include:
a. Reduced driving functions.
b. Advanced emission pollutants.
c. Increased oil consumption.
d. Hard to start your cold car.
e. Trembles during idling.

The car makers fail to mark the time to remove carbon buildup of cars. Normally, a car owner fails to remove engine carbon buildup unless it is found by the technician an abnormal circumstance or during routine maintenance. The followings are some useful methods to cut and prevent carbon buildup:
a. Use of high-quality petroleum and diesel
b. No idling for long
c. Avoiding frequent stepping on the gas pedal
d. Periodic maintenance (overhaul)

The GEM hydrogen production module series made by GOC is developed under demands for various hydrogen amounts in various fields. System integration of this series is quite easy since it strictly and mainly affords hydrogen and meets the demands for it. The ORP part majorly depends on the back-end hydrogen-mixing technology. GOC fails to make such technology available, but the real tests and feedbacks of our clients do prove that the hydrogen water equipment in coordination with the GEM series made by GOC can produce hydrogen water with ORP < -500mv.
