OUTLINE
1UR-FE Engine
The 1UR-FE is a 4.6-liter, 32-valve DOHC V8 engine. The engine uses the Dual Variable Valve Timing-intelligent (Dual VVT-i) system which achieves optimal valve timing by using an electronic motor to actuate the intake camshaft and the engine oil pressure to actuate the exhaust camshaft. In addition, this engine uses the Direct Ignition System (DIS), Acoustic Control Induction System (ACIS), and Electronic Throttle Control System-intelligent (ETCS-i). These control functions achieve improved engine performance, quietness, fuel economy and clean emissions.

1UR-FSE Engine
The 1UR-FSE is a 4.6-liter, 32-valve DOHC V8 engine. The engine uses the Dual Variable Valve Timing-intelligent (Dual VVT-i) system which achieves optimal valve timing by using an electric motor to actuate the intake camshaft and the engine oil pressure to actuate the exhaust camshaft. In addition, this engine uses the Direct injection 4-stroke gasoline engine Superior version (D-4S) which uses both the direct injection and port injection systems, Direct Ignition System (DIS), Acoustic Control Induction System (ACIS) and Electronic Throttle Control System-intelligent (ETCS-i). These control functions achieve improved engine performance, quietness, fuel economy and clean emissions.
