Toyota ZR engine

The ZR engine gasoline-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. Most 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.

2ZR-FAE
2ZR-FAE

The Toyota 2ZR-FAE is a DOHC, 16-valve, 1.8 L (1,798 cc) this engine adopts the Valvematic system. This all-new engine is progressively replacing the 1ZZ-FED and 2ZR-FE engine in most applications. Variants of this engine produce 104–110 kW (139–148 bhp) and 171–175 N⋅m (126–129 lbf⋅ft) of torque. Compression ratio is 10.5:1 and redline is at 6600 rpm. The engine consumes 5–10% less fuel than the 2ZR-FE depending on the application.[4]

A special version of the 2ZR-FAE was introduced by Toyota in 2016 for the Taiwanese version of the Toyota Sienta. Unlike the original 2ZR-FAE, this version was created by simply adding the Valvematic system to the standard 2ZR-FE engine used in the Toyota Corolla Altis sold there, resulting in total power of 140 PS (103 kW; 138 hp) at 6200 rpm and a peak torque of 172 N⋅m; 127 lbf⋅ft (17.5 kg⋅m) at 4000 rpm.[5]

Applications

2ZR-FBE

The Toyota 2ZR-FBE is A flex fuel version of the 2ZR-FE the DOHC, 16-valve, 1.8 L (1,798 cc) engine also equipped with Dual VVT-i and Valvematic. Output for this engine is rated at 141 hp (105 kW) at 6000 rpm and 131 lb⋅ft (178 N⋅m) of torque at 4000 rpm.

Applications

2ZR-FXE

The Toyota 2ZR-FXE is a 1.8 L (1,798 cc) Atkinson cycle variant of the 2ZR-FE.[8] 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; 99 PS) and 142 N⋅m (105 lb⋅ft) of torque, paired with electric motor/generators in the hybrid drive system; together the engine and electric motors produce up to 100 kW (134 hp; 136 PS) and 207 N⋅m (153 lb⋅ft). Maximum thermal efficiency is about 38.5%.[9]

For the 2016 Toyota Prius, output is 95 hp (71 kW) at 5200 rpm and 105 lb⋅ft (142 N⋅m) of torque at 3600 rpm, or when paired with electric motor/generators 71 hp (53 kW) and 120 lb⋅ft (163 N⋅m) of torque in the hybrid drive system; together the engine and electric motors produce up to 121 hp (90 kW). Maximum thermal efficiency is about 40%.
