ENGINE UNIT


  1. OUTLINE


    1. The 3ZR-FE engine is an in-line 4-cylinder, 2.0-liter, 16-valve DOHC engine. This engine uses the Dual Variable Valve Timing-intelligent (Dual VVT-i) system, Acoustic Control Induction System (ACIS), Direct Ignition System (DIS) and Electronic Throttle Control System-intelligent (ETCS-i). These systems have been developed to realize high performance and fuel economy, and reduce exhaust emissions.
