As we all know, a piston engine is a reciprocating engine, it has to moved up and down to produce power. The basic component used in a piston engine is the piston itself, valves, camshaft, crankshaft and the spark plug. It need four types of event (called stroke) to produce one complete cycle. http://kereta.info/video-struktur-enjin-kereta-dan-bagaimana-ia-berfungsi/
But for a rotary wankel engine, which is use in the Mazda RX3, RX7 and RX8, it is a different story.First of all a rotary engine doent use a piston. Even the camshaft is not needed for a rotary engine.A rotary engine mainly consist of rotor housing, rotor, eccentric shaft, intake port, exhaust port and a spark plug
By using a rotary engine, fe advantage can be gained, first, the rotary wankel doesnt reciprocate, which mean there is a lot less vibration compared to a piston engine. Second, the rotary engine gives high power to capacity ratio and also high power to weight ratio.A 1.3l RX7 engine can produce 280bhp easily with the help of a turbocharger. But the main draw back is the fuel consumption Even if it is a 1.3L engine,the fuel consumption is very high and comparable to a 3liter engine.
The basic working principle of the engine is simillar to a piston engine, there is an intake stroke, compression stroke, combustion stroke and exhaust stroke.But the rotor moves in a rotation rather tha reciprocate like the piston.

cool..engine parts is really interesting to learn..
Mazda Renesis engine are high revving engine-so for those who love high revvy engine to redline that can last all day; this is the car. The actual rotors spin at 1/3 the rotation of the crankshaft so 9000rpm is actually only spinning 3000 rpm’s for the actual rotor itself.
Renesis engine longivity in question? I heard someone mentioned “your accessories will probably die on you before the Renesis does!”. I think it’s the last non-turbo engine you should be worried about. Rotary engine is no different with any other piston engine-just make sure you take good care on the lubrication and coolant.
For Japanese tax purposes, the displacement of Wankel engines is defined as the equivalent of 1.5 times the nominal displacement. So the 1.3 L 13B engines count as just under 2.0 L for these purposes. Here in Malaysia we’re lucky.
betul2..
sebijik mcm aku belajar dulu..
-less vibration
-high power
hello sir….can you sent me a full wiring diagram for engine mazda rx-7 13 bridge port pls…i need for help sent me at my email [email protected]…..pls..inform me at email please
