rotary engine

n.
An engine, such as a turbine, in which power is supplied directly to vanes or other rotary parts.

rotary engine

n
1. (Automotive Engineering) an internal-combustion engine having radial cylinders that rotate about a fixed crankshaft
2. (Automotive Engineering) an engine, such as a turbine or wankel engine, in which power is transmitted directly to rotating components

ro′tary en′gine


n.
1. an engine, as a turbine, in which the impelling fluid produces torque directly rather than by acting upon reciprocating parts.
2. an internal-combustion engine, as the Wankel engine, whose power is developed by a rotor revolving in the combustion chamber.
3. a revolving radial engine.

Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor.
Its all-new SkyActiv-R rotary engine aims to fix the three biggest issues of earlier rotary engines, namely fuel economy, emissions and reliability.
Known as the Renesis, this engine was designed to reduce exhaust emission and improve fuel economy, which were two of the main drawbacks of rotary engines.
The decision was made due to weak sales as rotary engines, while noted for their high output despite their small size, are not fuel-efficient enough amid growing consumer preferences for more eco-friendly cars and tougher environmental regulations around the world.
Mazda Motor Corporation (TYO: 7261), a Japan-based automaker, is halting production vehicles with rotary engines in June 2012.

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.
Buyers had little patience for the engine's poor fuel economy, ordinary performance (0-60 mph took almost 13 seconds thanks to the lack of torque and lazy semiautomatic three-speed), thirst for oil (a lot of it found its way past the rotor seals, a problem--in smaller proportions--to this day for rotary engines), and its propensity to self-destruct.
Rotary engines thrive on revs, but while you have to work them hard for maximum performance theynever feel strained.
Mazda acquired the rights to Dr Wankel's work many years ago and it is now the only car maker which uses rotary engines.
