Toyota ZR engine

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.

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). This new engine is now replacing the 3ZZ-FE engine in most applications. 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.

1ZR-FAE

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 132 hp (97 kW) at 6400 rpm and 118 lb·ft (160 N·m) of torque at 4400 rpm for the Avensis. Compression ratio has been increased to 10.7:1, red line is at 6600 rpm. Valvematic varies the intake valve lift between 1mm and 11mm according to load and RPM.[1]

Applications

2ZR-FE

The Toyota 2ZR-FE is a DOHC, 16-valve, 1.8 L(1798 cc)[2] engine also equipped with Dual VVT-i.

This new engine is now replacing the 1ZZ-FE engine in most applications.[3] Output for this engine is rated at 98–103 kW (132–138 hp) at 6000 rpm and 173 N·m (127.5 lb·ft) of torque at 4400 rpm for the Corolla, Matrix, and Vibe and 95 kW (128 hp) and 171 N·m (126 lb·ft) of torque in the Scion xD.

2ZR-FAE

The Toyota 2ZR-FAE is a DOHC, 16-valve, 1.8 L (1797 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]

Applications

2ZR-FXE

The Toyota 2ZR-FXE is a 1.8 L (1798 cc) Atkinson cycle variant of the 2ZR-FE.[5] 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) 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) and 207 N·m (153 lb·ft). Thermal efficiency is about 38.5%.[6]

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

Applications

3ZR-FBE

A flex fuel version of the 3ZR-FE was released in March 2010 in Brazil with 153 PS (113 kW; 151 bhp) when running on ethanol.[7][8]

Applications

4ZR-FE

The Toyota 4ZR-FE is a 1.6 L (1,598cc) DOHC, 16-valve engine with Dual VVT-i. Output for this engine is rated at 87 kW (117 hp) at 6000 rpm and 150 N·m of torque at 4400 rpm. It is very similar to 1ZR-FE.

Applications

Applications

Specification is similar to 2ZR-FXE & a region-coded model due to various reasons.

Production

The 1.6L and 1.8L ZR engines are built in Tianjin FAW Toyota Engine Co., Ltd. (TFTE) Plant No. 2, beginning in April 2007 [9] and in the West Virginia Plant for Corolla's production in the United States and Canada.[10]
