ENGINE UNIT GENERAL


  1. OUTLINE


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

    2. This engine uses a high-expansion ratio Atkinson cycle, Variable Valve Timing-intelligent (VVT-i) system, Direct Ignition System (DIS), Electronic Throttle Control System-intelligent (ETCS-i) and Exhaust Gas Recirculation (EGR) system employing a highly efficient EGR cooler. In addition, use of an electric water pump has enhanced warm-up performance and reduced cooling losses. Thus, improved engine performance, quietness, fuel economy, and cleaner emissions have been achieved.
