OUTLINE
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.
This engine uses a direct injection system and a common-rail system to realize higher performance, good fuel consumption, clean emissions, low noise and low vibration.
The engine use a oxidation catalyst and Diesel Particulate Filter (DPF) catalytic converter to improve the exhaust gas cleaning performance.
