The term rotary piston engine can have several meanings:Rotary engine, the piston engine that rotates in operation, as used on World War I fighter aircraftPistonless rotary engine, the engines which use rotors or rotary pistons instead of conventional reciprocating pistons
Piston for sure gets better milage unless you have a V8 or higher. Rotary drinks its gas.
The RX stands for Rotary eXperiment. As you may know, the Mazda RX series of vehicles are not powered by conventional piston engines like 99% of all other vehicles on the road. Instead, they are powered by a rotary engine, also known as a Wankel engine.
The Wankel rotary engine is a differing type of engine as opposed to the standard piston engine. The Mazda line of cars is the one that uses this type of engine.
The current rotary engine displaces 1.3 liters. 1.3 liters in a rotary is approximately equal to 2.6 liters of piston engine
If you are speaking of the 13B N/A, the pistons that actuate the 6th port sleeves operate via vacuum from the "Pick up Tube" on the catalytic converter on the Exhaust piping. Either you have a rotary engine or a piston engine.
Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.
The engine's crankshaft converts the up-and-down motion of the pistons into rotary motion. This rotary motion is then transmitted to the transmission and wheels to propel the vehicle forward.
The crankshaft and connecting rod (or piston rod).
It connects the piston to whatever the design calls for the piston to push or pull on. In a combustion engine, the piston rod connects the piston to the crankshaft, turning linear reciprocating motion into rotary motion.
Rotary or Wankel engine.
The rotary system is more accurate. You can use the conventional system but I recommend the rotary.
