Toyota ZR engine


The ZR engine is a family of straight-four 16-valve all-aluminum and water cooled gasoline engines with a die-cast aluminum block and variable valve timing developed by Toyota Motor Corporation, produced from 2007. Engines displace from 1.6 to 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.

[Image:Toyota 2ZR-FAE Engine.jpg|200px|thumb|2ZR-FAE]
The Toyota 2ZR-FAE is a DOHC, 16-valve, engine equipped with the Valvematic system.
This all-new engine is progressively replacing the Japan-built 1ZZ-FE and 2ZR-FE engine in most applications.
Variants of this engine produce and 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.
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 at 6200 rpm and a peak torque of at 4000 rpm.
;Applications:

2ZR-FBE

The Toyota 2ZR-FBE is a flex fuel version of the 2ZR-FE the DOHC, 16-valve, engine also equipped with Dual VVT-i and Valvematic. Output for this engine is rated at at 6000 rpm and of torque at 4000 rpm.
;Applications:

2ZR-FXE

The Toyota 2ZR-FXE is a Atkinson cycle variant of the 2ZR-FE. It has the same bore and stroke, but the compression ratio is increased to 13.0:1, and the inlet valve closing is late-staged. The net result is that the engine has a greater effective expansion than compression. Output is at 5200 rpm and of torque at 4000 rpm, paired with electric motor/generators in the hybrid drive system; together the engine and electric motors produce up to and.
Maximum thermal efficiency is about 38.5%.
For the 2016 Toyota Prius, output is at 5200 rpm and of torque at 3600 rpm, or when paired with electric motor/generators and of torque in the hybrid drive system; together the engine and electric motors produce up to. Maximum thermal efficiency is about 40%.

Production

The 1.6 L and 1.8 L ZR engines are built in Tianjin FAW Toyota Engine Co., Ltd. Plant No. 2, beginning in April 2007 and in the West Virginia Plant for Corolla's production in the United States and Canada. The 1.8L Hybrid FXE engines are built in Toyota's Deeside engine manufacturing plant in the UK and shipped to their Burnaston, UK plant to be fitted into the Corolla Hatch and Touring Sport versions. The plant also supplies these engine parts to Toyota's assembly lines in France, Turkey, South Africa and Japan.
