D4D engine from Toyota - what you should know about the unit?

The motor was developed in cooperation between Toyota and Denso Corporation. It uses solutions known from other modern diesel engines. These include, for example, the operation of ignition maps when controlling the engine using TCCS.

When was the D4D engine created and in which vehicles is it used?

Work on the D4D block began back in 1995. The distribution of the first cars with this engine began in 1997. The main market was Europe, because the unit was not very popular in Asia or the United States, despite the fact that Toyota sells the most cars there.

The D4D engine is used in Toyota diesel engines, but there are exceptions to this rule - this is the case when it comes to units where the D-CAT system is used. This is a development of the D4D system and the injection pressure is higher than the original system - 2000 bar, and not the range from 1350 to 1600 bar. 

Popular unit variations from Toyota

One of the most popular Toyota engine options was the 1CD-FTV. Equipped with Common Rail system. It had a working volume of 2 liters and a power of 116 hp.

What are the most common diesel problems?

One of the most common malfunctions is the failure of injectors. The Toyota D4D engine does not idle smoothly, and also consumes a large amount of fuel, or is extremely noisy.

There are failures in blocks 3.0 D4D. They relate to the burnout of the sealing rings, which are made of copper and are installed on the fuel injectors. A sign of a malfunction is white smoke coming from the engine. However, keep in mind that with regular maintenance of the unit and replacement of components, the D4D engine should repay you with smooth and stable operation.
