Toyota AZ engine
From Wikipedia, the free encyclopedia
The Toyota AZ engine family is a straight-4 piston engine series. The AZ series uses an aluminum engine block and aluminum DOHC cylinder heads. It uses MFI fuel injection, has 4 valves per cylinder with VVT-i and features forged steel connecting rods.

[edit] 1AZ-FSE
The 1AZ-FSE is a 2.0 L (1998 cc) version. Bore is 86.0 mm and stroke is 86.0 mm. Output is 145 hp (108 kW) at 5700 RPM with 145 ft·lbf (196 N·m) of torque at 4000 RPM. The 1AZ-FSE features Toyota's D-4 direct injection system.
Applications:
- Toyota Avensis
- Toyota Avensis Verso
- Toyota RAV4
[edit] 2AZ-FE
The 2AZ-FE is a 2.4 L (2362 cc) version built in Georgetown, KY. Bore is 88.5 mm and stroke is 96 mm. Output is 157 hp (117 kW) at 5600 RPM with 162 ft·lbf (220 N·m) of torque at 4000 RPM. The 2AZ-FE also has one-piece cast camshafts.
Applications:
The 2007 Toyota RAV4 produces 166 hp (123 kW) at 6000 RPM and 165 ft·lbf of torque at 4000 RPM [1].
[edit] 2AZ-FXE
The 2AZ-FXE is a variant of the 2AZ-FE. It has the same bore and stroke, but has a higher physical compression ratio of 12.5:1, and the inlet valve closing is retarded. The net result is that the engine has a greater effective expansion than compression – making it Atkinson cycle, rather than the conventional Otto cycle.
The reduction in cylinder charge means reduced torque and power output, but efficiency is increased. This combination makes the 2AZ-FXE suitable for use in hybrid vehicles, where peak torque and power demands can be met by the electric motor and battery.
Maximum output when used in the Camry is 147 hp (108 kW) at 6000 RPM with 138 ft·lbf (187 N·m) of torque at 4400 RPM.
Applications:
- Toyota Estima Hybrid
- Toyota Camry Hybrid
