ENGINE UNIT GENERAL


  1. OUTLINE


    1. 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.

    2. The 1KD-FTV engine mounted in Europe models, which is based on the previous 1KD-FTV engine, has undergone a variety of modifications (swirl ratio, combustion chamber shape and injector nozzle radius optimization, etc.), along with a reduction in the size of the turbocharger, and optimal arrangement of the oxidation catalyst, etc. This has led to a substantial improvement in power output, and allows it to conform to the EURO IV (C/D mode: Chassis Dynamo mode) regulations without using complex and expensive systems such as DPF, as well as realizing higher performance and cleaner emissions.
