Models like the i20, i30, Rio, Ceed, and Venga were equipped with the 1.4-liter Hyundai D4FC or 1.4 CRDi diesel engine, which was manufactured at a facility in Türilina, Slovakia, between 2010 and 2018. Such a unit was updated for Euro 6 environmental standards and existed in two generations for Euro 5 environmental standards.
A 1.4-liter U2 diesel made its debut on the Kia Venga model at the start of 2010. The motor had the same torque of 220 Nm but was available in two versions with 75 and 90 horsepower. With a cast-iron block, an aluminum 16-valve DOHC cylinder head with hydraulic compensators, a timing chain drive, a traditional MHI TD025S2 turbine, and a 1800 bar Bosch Common Rail fuel system, this is a contemporary diesel unit for Euro 5.
An upgraded version of this unit debuted in 2014 for the stricter Euro 6, which was identified by a torque increase to 240 Nm and a compression ratio reduction from 17 to 16.
The engines D3FA, D4FA, D4FB, D4FD, and D4FE are also part of the Hyundai U family.
The engine was mounted on:
- Hyundai i20 1 (PB) in 2010 – 2012; i20 2 (GB) in 2014 – 2018;
- Hyundai ix20 1 (JC) in 2010 – 2018;
- Hyundai i30 2 (GD) in 2011 – 2015;
- Kia Ceed 2 (JD) in 2012 – 2013;
- Kia Venga 1 (YN) in 2010 – 2018;
- Kia Rio 3 (UB) in 2011 – 2017; Rio 4 (YB) in 2017 – 2018.

Disadvantages of the Hyundai D4FC engine
This diesel engine has a very dependable Bosch Common Rail fuel system, and the only complaints on specialized forums are about the fuel pressure regulator on the rail failing frequently.
The rapid contamination of the intake manifold, which needs to be cleaned every 50,000 kilometers, is a major problem for the owner. The EGR valve becomes clogged around the same time.
A timing chain, which is made up of two roller chains, is characterized by a very small resource: the valves bend when the chain jumps, and occasionally they stretch out and rattle violently by 100,000 kilometers.
The crankshaft position sensor, the unreliable low-pressure fuel pump, and frequent oil leaks from beneath the valve cover are additional weak points.
