ENGINE UNIT GENERAL

OUTLINE
1. The 1KD-FTV engine is newly provided on the new models.
2. The 1KD-FTV TOYOTA D-4D (Direct Injection, 4-stroke Common-rail Diesel Engine) is a 3.0-liter, inline 4-cylinder, 16-valve DOHC with intercooler turbocharged diesel engine. Based on the 2KD-FTV engine of the previous model, various parts of this engine have been revised to realize high performance, clean emissions, low noise and low vibration.
