The RX-Vision is slightly longer and wider than Jaguar's F-TYPE, and a fair bit lower thanks to the rotary engine
's small size, but the production model (which insiders expect to be called RX-7) will probably be smaller than the concept car, and more dimensionally akin to the Porsche Cayman.
The company says it will continue its research and development on rotary engines
, indicating that cars with such engines might hit the market again in the future.
In the early 1960s, Mazda launched its first passenger car models and began developing rotary engines
. Still headquartered in Hiroshima in western Japan, Mazda today ranks as one of Japan's leading automakers, and exports cars to the United States and Europe for over 30 years.
The owner should be checking the oil very regularly (Mazda recommends every second fuel fill) as the rotary engine
uses oil by its nature.
However, in a rotary engine
, the intake, combustion, and exhaust chambers are separate from one another.
The Wankel rotary engine
is the most known rotary heat engine, patented in 1954 by Felix Wankel.
WAY AHEAD The Mazda RX-8 is powered by a hydrogen rotary engine
Seita Kanai, Mazda's director and senior executive officer in charge of research and development, said: "For future post-fossil fuel vehicles, Mazda considers that hydrogen energy will be a main power source, and has been conducting research into both fuel cell vehicles and hydrogen rotary engines
for 15 years.
Mazda prefers to calculate the rotary engine
's size as being the equivalent of just 1.3-litres, which makes the power output seem mightily impressive at 228bhp, which is the same as that of a Mercedes SLK 280.
But under this new stylish skin, the only choice will be a significantly improved and retuned version of the 228bhp 1.3-litre rotary engine
Figure 2 shows the variation of the volume of a rotary engine
with the following specific parameters: the ratio of compression [epsilon] = 8.5, the values of ovalizations [e.sub.1] = 9.25 mm, [e.sub.2] = 14.72 mm , the radius of the piston R = 130 mm, the breadth of the piston [l.sub.p] = 125 mm.
A hydrogenpowered version of Mazda's rotary engine
provides the oomph without any of the emissions and the ultranarrow rear tyres ensure minimum rolling resistance.
A recent--and rare--opportunity at his workplace to tear down a Mazda rotary engine
increased his curiosity about the Wankel engine.
The company is developing a rotary engine
that can run on hydrogen or gasoline and is also linked to an electric motor.
