ENGINE UNIT GENERAL


  1. OUTLINE


    1. The 2KD-FTV TOYOTA Direct injection 4 stroke common-rail Diesel engine (D-4D) is an in-line 4-cylinder, 2.5-liter, 16-valve DOHC, turbocharged diesel engine. This engine uses the direct injection system and common-rail system to achieve high performance, clean emissions, low noise and low vibrations.

    2. A 2KD-FTV High Version engine, which has a higher power output than the normal 2KD-FTV engine, is also available. The 2KD-FTV and 2KD-FTV High Version engines are equipped with ECMs containing engine control programs that differ from each other. However, both engines share the same mechanical components.

    3. An intercooler is provided on the models for Europe. This lowers the intake air temperature and improves power output.
