Piston Engines
Even though Mazda is better 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 cams, aluminum blocks, and an innovative block containing both the engine and transmission in one unit. This section sumamrizes piston engine developments. Note that Mazda has produced many piston engines, but only V-twin, straight-4, and V6 configurations, never a V8, I5, or V12!
V-twin
- V-twin - Half-liter air-cooled V2 (1961-1963)
Straight-4
- OHV engines - 300 cc–1.2 L OHV I4 (1961–1974)
- xC engines - 1.0 L–1.8 L SOHC I4 (1965–1983)
- E family - 1.1 L–1.5 L SOHC I4 (1980–1986)
- F family - 1.8 L–2.3 L SOHC I4 (1979–1999)
- G family - 2.5 L–2.6 L I4 (1989–1999)
- B family - 1.3 L–1.8 L SOHC/DOHC I4 (1987–present)
- Z/MZ family - 1.25 L–2.3 L DOHC I4 (1995–present)
- Keicar engines - Suzuki-made I4
- Diesel - 1.4 L–4.6 L I4
- YF - 2.0 L I4 for Mazda Tribute
V6
Mazda has created three families of in-house V6 engines. Today, however, their primary engine is a Ford design.
- J family - 2.0 L–3.0 L 90° V6 (–1995)
- K family - 1.8 L–2.5 L 60° V6
- Diesel - 4.1 L–5.5 L ZB/ZC V6
- AJ/MZI - 2.5 L and 3.0 L V6 - The Mazda version of the Ford Duratec DOHC V6 is, of course, not a Mazda engine at all.
Wankel engines
Mazda is the only producer of successful Wankel engines, positioning them as a prime sports car powerplant. All of Mazda's Wankels are based on their first design of the 1960s, though there have been significant developments over the four decades since.
