Mazda anniversary: 18 years of research on hydrogen vehicles

Mazda anniversary: 18 years of research on hydrogen vehicles
In 1991, Mazda introduced at the Tokyo Salon model HR-X, the first vehicle equipped with a hydrogen rotary engine. This was the beginning of a long line of innovations, the company developed in the 90s 5 other models.

Mazda currently produces two models which use hydrogen as fuel - Mazda RX-8 Hydrogen RE and Mazda5 Hydrogen RE Hybrid, both on public roads in Japan and recently in Europe.

Mazda rotary engine has chosen to integrate technology for hydrogen due to unique architecture, ideal for this type of fuel. The energy released from burning a quantity of hydrogen is lower than similar petrol disadvantage offset design of the combustion chamber and the direct injection rotary engine. However, the combustion cycle longer rotary engine helps fuel efficient hydrogen.

Mazda RX-8 Hydrogen

The first concept model RX-8 used in addition to gasoline and hydrogen fuel was tested in 2004 and just two years later the first commercial vehicles were delivered to customers.

Initially developed in Japan, the model has been adapted for the Norway, which is already used in the project HyNor (for creating an infrastructure based on hydrogen). Version for Europe is equipped with a manual 5-gears, the option of switching to go between the two types of fuel elements and specific model RX-8 Facelift series - grille and rear spoiler redesenate, headlines with a new design and brake lamps with LEDs, and wheel and central console us.

Since the hydrogen infrastructure is still in its early, Mazda has chosen not to produce a model that uses only hydrogen feed. Mazda RX-8 Hydrogen is equipped with a petrol tank, it provides necessary fuel where hydrogen fuel is not available. The engine developed by Mazda for this model develops 80 kW and provides an autonomy of 100 km, the emissions are zero.

Mazda5 Hydrogen RE Hybrid

In addition to the "dual-fuel" of equipment RX-8 Hydrogen, Mazda5 and integrating hybrid technology, combining hydrogen rotary engine with an electric generator. Besides generating system includes an inverter and a battery. Unlike the RX-8, where this model, engine displacement is used for the electric drive providing hydrogen energy to generate electricity.

The battery has several functions. It stores energy produced by hydrogen engine, resulting in the capture braking energy and supplies electric engine. The system is controlled automatically, driver intervention is minimal. Decide whether the vehicle is required starting or stopping the engine on hydrogen and battery charging or use. Passengers can see through indicators on board the way energy is used and each element of the system.

To keep supplies Zoom-Zoom, Mazda vehicle fiecăui specifically, the system is optimized so that the power increases in proportion to the energy released from rotary engine. Hybrid technology developed by the company increase efficiency vehicle Mazda5 Hydrogen RE Hybrid with an autonomy of 200 km. Hybrid system can generate up to 110 kW, with 40% more power than if the model RX-8 Hydrogen.

Mazda5 Hydrogen RE Hybrid incorporates elements and passenger-friendly environment. Board, central console, which takes the hydrogen tank and upholstery on seats and doors are made of "bio materials, using raw materials derived from natural substances.
