OUTLINE
The 2GR-FKS engine is a 3.5-liter, 24-valve DOHC V6 Direct injection 4-stroke gasoline engine Superior version (D-4S). This engine uses both direct injection and port injection systems. In addition, this engine uses the Variable Valve Timing-intelligent Wide (VVT-iW) control, Variable Valve Timing-intelligent (VVT-i) control, Direct Ignition System (DIS), and Electronic Throttle Control System-intelligent (ETCS-i). These control functions achieve improved engine performance, fuel economy, and clean emissions.
