Toyota ZZ Engine
The Toyota ZZ engine family is a straight-4 piston engine series. The ZZ series uses an aluminum engine block and aluminum DOHC 4-valve cylinder heads with iron cylinder liners, a first for Toyota. The camshafts are chain-driven. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimized for economy and torque, while the latter is a "square" design optimized for high-RPM power. The ZZ family replaced the extremely popular cast-iron 4A engines.
Toyota engine names are interpreted as follows. The leading number denotes the generation, and the next one or two letters, followed by a hyphen, specify the engine family. The remaining letters, following the hyphen, describe the engine's major features. For example, the 2ZZ-GE can be decoded as being the second generation of the ZZ engine series and features a performance-oriented cylinder head with widely-angled valves (G) and electronic fuel injection (E).
