HYDROGEN ENGINE RETROFIT

HYDROGEN ENGINE RETROFIT

We are developing a new hydrogen conversion technology for internal combustion engines.

Thanks to our knowledge of the di-hydrogen molecule and our combustion expertise, we can exploit the combustion properties of this fuel.

Our technology can be adapted to a wide range of engines, from single-cylinder to multi-cylinder

BenefiTS

ZERO CO2

Our hydrogen engines generate zero CO2 emissions, from tank to wheel.

ZERO CO2 ICON
COMPETITIVE COSTS

Compared to electric a/o fuel cells retrofit, we can keep 95% of the existing vehicle. This pragmatic approach also allows us to have a more competitive offer.

COMPETITIVE COSTS ICON
EASE OF USE & MAINTENANCE

Can be recharged in just a few minutes, and maintained like a conventional internal combustion engine.

EASE OF USE & MAINTENANCE ICON
EFFICIENCY AND ROBUSTNESS

Optimized efficiency thanks to our technology: significantly reduced fuel consumption, increased range. What's more, unlike other zero-CO2 technologies (electric or fuel cell), our motors can withstand intensive use in harsh environments (cold, heat, humidity and dust).

OUR PROCESS

Design and simulation image
01

Design and simulation

We simulate the behaviour of engines to optimize each configuration with our in-house numerical tools. Specific component are designed to control mixing and combustion processes.

Engine CONVERSION with the H2R KIT

Once the calculations and simulations have been validated, we proceed to manufacture the conversion kit dedicated to your engine, and install it on your original block.

We are operating on the top of the engine (injectors, cylinder, cylinder head, ECU reprog, etc...).

Engine calibration and validation image
03

Engine calibration and validation

Before being put into service, engines are tested on benches, both steady state operating conditions and transients are considered.

Hydrogen combustion and injection dedicated control strategies are developed according to customer needs.

VEHICLE INTEGRATION

Our solutions are integrated into your vehicles before they are 100% operational and ready for use, whether for prototype pilot projects or fleet conversions.

1. Implementation of the engine while keeping the existing powertrain.

2. Our engineers pay particular attention to the design of a cell dedicated to gas storage tanks, which must be able to integrate securely into the chassis.

We are convinced that the future will be made up of a mixed energy mix.
That's why the VISION’s technology has also been developed to run on biogas & biomethane.
This gas - produced from biomass and wastes - is available in many stations in France.
It’s a complementary response to hydrogen for decarbonizing industry in the short and medium term.
In addition, our technology is compatible with high-octane fuels (e.g. e-fuel, bioethanol).

World premiere : hydrogen karting exhibition during the Pau Grand Prix

Our singlecylinder engine (proof of concept) has been integrated into the chassis of a Kart, which has been retrofited with hydrogen. Following conclusive private testing, the team was able to carry out an official run on track, in front of the 30,000 spectators at the Pau Grand Prix. This is the first time in history that a hydrogen-powered single-seater has been driven in front of the public.

The first POC engine of VISION Technology : Hydrogen singlecylinder

The first achievement of the VISION Technologie teams, this 450cc 4-stroke engine has been completely reworked in the combustion chamber. This first engine enabled the teams to design the VISION engine technology, enabling gasoline engines to be converted into high-efficiency hydrogen engines Test results are satisfactory, and the engine is ready to be integrated into a demonstration vehicle. A patent on the architecture of the combustion chamber may follow.
