The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]
The Renesis won International Engine of the Year and Best New Engine awards 2003 [26] and also holds the "2.5 to 3 liter" (note that the engine is designated as a 1.3–litre by Mazda) size award [27] for 2003 and 2004, where it is considered a 2.6 L engine, but only for the matter of giving awards.
Thus the Wankel is a 2:3 type of rotary engine, i.e., its housing's inner side resembles a two lobes oval-like epitrochoid (equivalent to a peritrochoid),. [25] In contrast, its rotary piston has a three vertices trochoid shape (similar to a Reuleaux triangle). Thus, the Wankel engine's rotor constantly forms three moving working chambers. [26]
When the engine valve is closed (lifter in a neutral position), the lifter is free to fill with oil. As the camshaft lobe enters the lift phase of its travel, it compresses the lifter piston, and a valve shuts the oil inlet. Oil is nearly incompressible, so this greater pressure renders the lifter effectively solid during the lift phase.

But when it comes to her sons Brandon, now 28, and Dylan, now 26, whom she shares with ex Lee, 62, "My kids are grown. I’m free. I’m free. Now I can play again," she told Madison, 25.
Another motorcycle with a rotary engine was Charles Redrup's 1912 Redrup Radial, which was a three-cylinder 303 cc rotary engine fitted to a number of motorcycles by Redrup. In 1904 the Barry engine , also designed by Redrup, was built in Wales: a rotating 2-cylinder boxer engine weighing 6.5 kg [ 3 ] was mounted inside a motorcycle frame.
