J1GR-FE
ENGINE
1. General
D
The 1GR-FE engine is a 4.0-liter, 24-valve DOHC V6 engine. In this engine, a Dual Variable Valve
Timing-intelligent (Dual VVT-i) system, in which the VVT-i system has also been added to the exhaust
side, and the roller rocker arm are used to minimize friction, offering excellent engine performance, fuel
economy and clean emissions.
D
The 1GR-FE engine is compatible with gasoline/ethanol mixed fuel which contains up to 20% ethanol
(E20). Unleaded gasoline with an octane rating of 87 (research octane number 91) or higher can be used
on this engine.
D
For detailed comparisons to the ’09 FJ Cruiser, see Major Difference (See page 8).
