Toyota 1AR-FE Engine Specifications
The Toyota 1AR-FE is an 1AR family inline four-stroke four-cylinder direct injection naturally aspirated gasoline engine produced by Toyota Motor Corporation.
This engine has aluminum cylinder block and aluminum cylinder head. The development of the
engine began in the late 2008.
The cylinder block height was increased for the new crankshaft with 105 mm
stroke. This way they achieved the increasing of engine displacement from 2.5 to
2.7 liter. There is the same aluminum DOHC 16-valve cylinder head with hydraulic
lifters. Both camshafts are equipped with variable valve timing system called
Dual-VVTi. The single-row timing chain drives camshafts. The engine features the
variable geometry intake manifold ACIS. There are many features also similar to
the 2AR engine. The main difference is the output of the 2.7 liters, mostly in
the torque numbers which is more actual for heavier vehicles like the Highlander
or Venza.
Engine code identification:
1 – 1st generation engine
AR – Engine family
F – Economy narrow-angle DOHC
E – Multi-Point Fuel Injection
