Fuel economy,
lower maintenance cost, and
reduced harmful emissions
How does hydrogen pre-mix help fuel economy? What is the reduction of exhaust emissions achieved with hydrogen-boost? And how hydrogen fuel enhancement helps reduce maintenance cost and extends the life of cars in general?
The answers to these questions can be found here, together with the explanation of the technology and the real-life results achieved:

and reduction of harmful emissions
Ever-increasing fuel prices and rising air pollution are major concerns worldwide. Quite logically, countries and municipalities have been looking for innovative technological solutions.
In the framework of the urban experimentation led by Urban Lab of the City of Paris, in 2018 HHO France was selected to join a group of 10 innovators to participate in “Urban Air Quality Project”. The aim of the project was to reduce harmful emissions and reduce fuel consumption in a variety of combustion engines.
In 33 applications, such as of cars, vans, lorries, forklifts, power generators, and even a river boat, the hydrogen-boost equipment was installed.

Hydrogen Generators
Antismog B1 (10th Generation)
Hydrogen generator B1 was designed on the occasion of a project with the City of Paris under the name “ANTISMOG“. The hydrogen generators were installed on multiple cars, vans, forklifts, electricity generators, and even a river boat.
The following results were achieved:
- Reduction of fine particulate matter released into the atmosphere after installation of a hydrogen generator on different vehicles between 66% to 82%
- Reduction of nitrogen oxides up to 5%
- Fuel economy up to 21%
The evaluation of the results was carried out by a group of independent experts composed of the companies Nomadeis and Mazars, for a period of 12 months, from June 2018 to June 2019.
Led by Urban Lab of Paris & Co, it was funded by the city of Paris, L’ADEME en Île-de-France and Caisse des Dépôts Ile-de-France, and was implemented with the support of Airparif.

How does hydrogen fuel enhancement work?
The efficiency of the most modern combustion engines hovers below 50%. For petrol engines, the upper limit of efficiency is closer to 35%. An incomplete or suboptimal combustion results in unburnt particles being rejected into the environment through the exhaust.
The addition of hydrogen improves the combustion process, allowing for a fuller fuel burn and thus resulting in reduction of unburnt fuel particles.
In addition to fuel economy, carbon deposits inside the engine are also significantly reduced.
This in turn inevitably leads to the following additional benefits for the vehicle from the installation of a hydrogen generator:
☑ Increased EFFICIENCY;
☑ Lower environmental impact;
☑ Lower operating costs;
1. FUEL ECONOMY
If hydrogen is added to the air-fuel mix, the combustion of the fuel accelerates and so the engine manages to burn fuel more efficiently…

Due to challenging working conditions, especially in urban driving, traffic jams and low quality fuels, the carbon deposits form on the following parts:
- Cylinder
- Piston head
- Piston rings
- Exhaust valves and valve seats…
3. INCREASES ENGINE LIFE
When carbon depositsare accumulated on the engine cylinder and the piston rings, the operation of the compression rings and the oil rings is hindered. The oil is not scrapedeffectively and the rest of the oil on the cylinder turns into soot…
