The 1.6-liter diesel engine Hyundai D4FB or 1.6 CRDi was produced from 2005 to 2020 at a plant in Slovakia and was installed on such popular models as Ceed, Soul, Elantra, Venga and i30. Modifications of this motor of the first and second generation were produced with a number of differences.
In June 2005, a 1.6-liter U-line diesel engine with 116 hp appeared on the Kia Cerato. By design, it was a typical Euro 4 diesel engine for its time, equipped with a Bosch CRS2 Common Rail fuel system with injection pressure up to 1600 bar, a cast-iron block, an aluminum 16-valve cylinder head with hydraulic compensators, a timing chain, a variable geometry turbine Garrett GT1544V, as well as an intake with swirl flaps. In addition to the 116 hp version of the engine, a 90 hp version was also installed on some models.
In 2008, the second generation of 1.6 CRDi diesel engines appeared under more stringent EURO 5 environmental standards with a number of differences not only in emission control: so the compression ratio was lowered from 17.3 to 17.0, a fuel system appeared with injection pressure up to 1800 bar and a Garrett GTB1444VZ turbine, some versions of this unit began to be equipped with a proprietary ISG start-stop system, and the engine power range was also seriously expanded: from 90 hp / 235 Nm to 136 hp / 400 Nm.
The engine was installed on:
- Hyundai i20 1 (PB) in 2008 – 2010;
- Hyundai ix20 1 (JC) in 2010 – 2018;
- Hyundai i30 1 (FD) in 2008 – 2012; i30 2 (GD) in 2011 – 2017; i30 3 (PD) in 2016 – 2018;
- Hyundai Accent 4 (RB) in 2010 – 2017;
- Hyundai Elantra 4 (HD) in 2006 – 2011; Elantra 6 (AD) in 2015 – 2020;
- Kia Ceed 1 (ED) in 2006 – 2013; Ceed 2 (JD) in 2012 – 2018;
- Kia Cerato 1 (LD) in 2005 – 2008; Cerato 2 (TD) in 2008 – 2013; Cerato 3 (YD) in 2013 – 2018;
- Kia Carens 3 (UN) in 2010 – 2013;
- Kia Soul 1 (AM) in 2008 – 2014; Soul 2 (PS) in 2014 – 2019;
- Kia Stonic 1 (YB) in 2017 – 2018;
- Kia Venga 1 (YN) in 2010 – 2019.

Disadvantages of the Hyundai D4FB engine
- The turbine of the first generation diesel engines did not last long, sometimes it was replaced at 30,000 km, and defective glow plugs were installed on the second generation units in the first year.
- The Bosch fuel system is reliable, often only the fuel pressure regulator fails. Also, sometimes the return pipes on the injectors burst or the booster pump fails.
- Even in this motor, a collector with swirl flaps very quickly overgrows with soot. It is necessary to clean it at least once every 50 thousand km and preferably together with the EGR valve.
- The timing drive does not have a high resource either, it here consists of two roller chains that can stretch and begin to rattle strongly already at a run of 120 – 150 thousand km.
- Also, the boost sensor regularly fails here, it simply breaks the wiring, and the crankshaft position sensor fails, banal cleaning often helps it.
