ENGINE UNIT GENERAL


  1. OUTLINE


    1. The 1KD-FTV TOYOTA Direct injection 4 stroke common-rail Diesel engine (D-4D) is an in-line 4-cylinder, 3.0-liter, 16-valve DOHC, turbocharged diesel engine with intercooler. This engine uses the direct injection system and common-rail system to achieve high performance, clean emissions, low noise and low vibrations.

    2. An intercooler is provided. This lowers the intake air temperature and improves power output.
