2ZR-FE

The ZR engine family, introduced in 2007 by Toyota Motor Corporation, uses a DOHC 16-valve cylinder head with a 4-cylinder die-cast block. Engines displace either 1.6 liters, 1.8-liters or 2.0-liters. All engines in this family are equipped with Toyota's dual VVT-i technology that optimizes both intake and exhaust valve timing. This engine family is also the first to use Toyota's Valvematic system first appearing on the Noah and Voxy in 2007 and then the European Avensis in 2009.

[edit] 1ZR-FE

The Toyota 1ZR-FE is a DOHC, 16-valve, 1.6 L (1598cc) engine equipped with dual VVT-i. This engine is available with either manual gearbox (5 Speed) or a "multi-mode" manual transmission (MM-T 5 Speed). For the Corolla Altis, the available transmission options are the manual gearbox (6 speed) or a 4 speed gate type automatic transmission. Output for this engine is rated at 124 hp (92 kW) at 6000 rpm and 116 lb·ft (157 N·m) of torque at 5200 rpm net.

  • Specifications:
  • Engine type : In-Line 4-cylinder DOHC 16-valve
  • Bore x Stroke : 80.5 x 78.5 mm
  • Compression Ratio : 10.2:1

The Toyota 1ZR-FAE is a DOHC, 16-valve, 1.6 L (1,598 cc) engine also equipped with Dual VVT-i and Valvematic. Output for this engine is rated at 130 hp (97 kW) at 6,400 rpm and 118 lb·ft (160 N·m) of torque at 4,400 rpm for the Avensis. Compression ratio has been increased to 10.7:1, red line is at 6600 RPM.[1]

[edit] 2ZR-FE

The Toyota 2ZR-FE is a DOHC, 16-valve, 1.8 L (1797 cc) engine also equipped with Dual VVT-i. This new engine is now replacing the 1ZZ-FE engine in most applications. Output for this engine is rated at 132–134 hp (98–100 kW) at 6000 rpm and 128 lb·ft (174 N·m) of torque at 4400 rpm for the Corolla, Matrix, and Vibe and 128 hp and 126 lb ft of torque in the Scion xD.

  • Specifications:
  • Engine Type : In-Line 4-cylinder DOHC 16-valve
  • Bore x Stroke = 80.5 x 88.3 mm
  • Compression Ratio : 10.0:1
  • Weight : 97 kg (without fuel)

[edit] 2ZR-FAE

The Toyota 2ZR-FAE is a DOHC, 16-valve, 1.8 L (1797 cc) engine also equipped with Dual VVT-i and the Valvematic system. This all-new engine is now[when?] replacing the 1ZZ-FED engine in most applications. Output for this engine is rated at 147 hp (110 kW) at 6400 rpm and 132 lb·ft (179 N·m) of torque at 4000 rpm for the Avensis. Compression ratio has been increased to 10.5:1, red line is at 6600 RPM. In the Toyota Allion / Toyota Premio it consumes 9% less fuel than the 2ZR-FE.[2]

[edit] 2ZR-FXE

The Toyota 2ZR-FXE is a 1.8 L (1798 cc) Atkinson cycle variant of the 2ZR-FE.[3] It has the same bore and stroke, but the compression ratio is increased to 13.0:1, and the inlet valve closing is retarded. The net result is that the engine has a greater effective expansion than compression. Output is 73 kW (98 hp) at 5200 rpm with 142 Nm (105 lb·ft) of torque at 4000 rpm.

[edit] 3ZR-FE

The Toyota 3ZR-FE is a 2.0 L (1,986cc) DOHC, 16-valve engine with Dual VVT-i. A flex fuel version was introduced in March 2010 in Brazil with 152 PS when running on ethanol.

  • Specifications:
  • Engine type : In-Line 4-cylinder DOHC 16-valve
  • Bore x Stroke : 80.5 × 97.6 mm
  • Compression Ratio : 10.0:1 (JDM)
  • 143 PS (105 kW) at 5,600 rpm (JDM)
  • 194 Nm (19.8 kg.m) of torque 3,900 rpm (JDM)
  • 13.4 km/L fuel consumption (10-15 Japanese test cycle: Toyota Voxy; Toyota Noah)
  • equivalent to 31.5 mpg(U.S.)
