Hyundai U engine


The Hyundai U engine is a series of three or four-cylinder diesel engines made for automotive applications by the Hyundai Kia Automotive Group. The U series of engines includes the smallest automotive diesel engines produced by Hyundai.

1.1 L (D3FA)

The U diesel engine is a 3-cylinder version of the 1.5L U series unit and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder, Delphi common rail direct injection, variable geometry turbocharger and intake air swirl control. Bore and Stroke are. It creates at 4,000 rpm and of torque between 1,750 and 2,500 rpm.
It is one of Hyundai's most efficient engines with a fuel consumption of, and emits 112 g/km of CO2. The engine also incorporates a 1½ engine order balance shaft mounted under the crankshaft driven by helical gears to manage engine vibration.
