ENGINE UNIT GENERAL


  1. OUTLINE


    1. The 2ZR-FXE is an in-line 4-cylinder, 1.8-liters, 16-valve DOHC engine.

    2. This engine uses a high-expansion ratio Atkinson cycle, VVT-i (Variable Valve Timing-intelligent) system, ETCS-i (Electric Throttle Control System-intelligent), and EGR system employing a highly efficient EGR cooler. In addition, use of an engine water pump assembly has eliminated the V-ribbed belt. Thus, improved engine performance, quietness, fuel economy, and cleaner emissions have been achieved.
