  1. OUTLINE


    1. The 1AD-FTV TOYOTA Direct injection 4 stroke common-rail Diesel engine (D-4D) is an in-line 4-cylinder, 2.0-liter, 16-valve DOHC turbocharged diesel engine with intercooler.

    2. This engine uses a direct injection system and common-rail system to achieve higher performance, clean emissions, low noise and low vibrations.

    3. This engine has 2 types; one type (models with DPF catalyst) uses both the Diesel Particulate Filter (DPF) catalyst and oxidation catalyst, and the other type (models without DPF catalyst) uses the oxidation catalyst only.
