Leverkusen, 15. October 2008 – Mazda tests vehicles with hydrogen circle engine on public straws for the first time outside of Japan. In Norway, the company has begun a practical test with the Mazda RX-8 Hydrogen Re together with Hynor (Hydrogen Road of Norway). Hynor is a joint project of industrial partners who want to demand hydrogen as a fuel in Norway’s transport sector and contribute to the construction of a hydrogen economy. According to Mazda, this test is the prelude to deliver a total of 30 vehicles that Mazda is liable to Hynor.
Hynor wants to build a realistic-functioning hydrogen infrastructure in Norway: There is a 580 kilometer "Hydrogen Highway" from Oslo to Stavanger with numerous hydrogen petrol stations. From the perspective of the Hynor Partner, Norway offers for this test from two grunden special advantages: On the one hand, the climatic conditions are favorable, because the land has almost everything from mated climate to bitter cold. In addition, Norway offers good prerequisites for the production of hydrogen from renewable energy sources, as much hydropower is available.
Hydrogen good for Wankel
Mazda is the only car manufacturer worldwide, which still produces circular piston engines in coarse series. According to Mazda, the so-called Renesis unit is better suited for combustion of hydrogen as an incoming lifting piston engine and is also easier to interpret operation with hydrogen. The main reasons: Hydrogen is highly attractive, resulting in the combustion chambers of reciprocating motors to problems such as misalungs. In grave motors, the air-fuel mixture is sprayed directly into the high-temperature combustion chambers, which are provided with hot exhaust valves,. For hydrogen, the very unfavorable conditions are. On the other hand, a circular flask motor has three work space. Inlet, combustion and outlet cycle are constantly changing. Therefore, according to Mazda, the hydrogen is in the inlet chamber at comparatively low temperatures and only occurs at the last moment before the actual round of the high temperatures of the combustion chamber.
