The Wankel engine (/ˈvaŋkəl̩/, VUN-kell) is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, followed by a commercially feasible engine designed by German engineer Hanns-Dieter Paschke. [1]
The LCR - 407 SGti engine is a single-rotor four-stroke, 407 cc (24.8 cu in) displacement, liquid-cooled, fuel injected, petrol, Wankel engine design, with a toothed poly V belt reduction drive with a reduction ratio of 3:1. It employs dual electronic ignition and produces 37 hp (28 kW) at 6000 rpm. [1]
Outdated annual Mazda Wankel "rotary" engine sales without RX-8 and without industry engines (data source: Ward's AutoNews) Mazda was fully committed to the Wankel engine just as the energy crisis of the 1970s struck. The company had all but eliminated piston engines from its products in 1974, a decision that nearly led to the company's collapse.
The NR642 is a twin-rotor Wankel engine. [1] It is a 588 cc (35.9 cu in) displacement [2] petrol engine design, with a heavy-duty [1] 2.94:1 [2] reduction gearbox. Cooling is provided by a fan for the rotors, plus liquid cooling for the housing. [1] [2] It was designed to meet JAR-E [2] and FAR 23 regulatory requirements. [1]
The Mazda RX-8 utilizes a rotary Wankel engine, and the non-reciprocating piston engine uses a triangular rotor inside a near oval housing, producing from 141 kW (189 hp) and 164 lb⋅ft (222 N⋅m) of torque, to 177 kW (237 hp) and 159 lb⋅ft (216 N⋅m) of torque from launch.

Although Mazda is well known for their Wankel "rotary" engines, the company has been manufacturing piston engines since the earliest years of the Toyo Kogyo company. Early on, they produced overhead camshaft, aluminum blocks, and an innovative block containing both the engine and transmission in one unit.
Wankel aircraft engine. The company's aircraft engine line consists of the single rotor Wankel AG LCR - 407 SGti four-stroke, 407 cc (24.8 cu in) displacement, liquid-cooled, fuel injected, petrol, Wankel engine that produces 37 hp (28 kW) at 6000 rpm and the dual rotor Wankel AG LCR - 814 TGti 814 cc (49.7 cu in) displacement, liquid-cooled, fuel injected, petrol, Wankel engine design, that ...
