Hyundai's lightweight eco-buster

Hyundai plans to tackle rising fuel prices head-on with a new emissions-busting 1.2-litre engine.

This new Kappa engine was developed over 48 months with the sole intent of getting the most out of each drop of fuel while keeping emissions within Euro 4 parameters.

"Small is beautiful"

"The world is thinking small like never before: smaller fuel consumption, smaller CO2 footprint, smaller overall emissions. Today small is beautiful," said Hyundai president and chief technology officer, Lee Hyun-Soon.

A number of weight and friction reducing measures have been adopted.

The engine block is made from high-pressure die-cast aluminium. This results in the engine weighing a mere 82.4 kg - a figure the manufacturer states is class-leading.

Kappa’s main block features a ladder frame construction for superior structural stiffness while its cylinders are fitted with cast-iron liners for improved abrasion durability.

Better consumption,lower NVH

And unlike a conventional engine where the centreline of the cylinder bore is vertically aligned with the rotating axis of the crankshaft, the Kappa’s centreline is offset by a small distance. This minimises the side force created by the pistons, resulting in an improvement in fuel consumption and a reduction in noise, vibration and harshness.

The four-cylinder produces close to 60 kW and has a peak torque figure of about 115 Nm, it is claimed.

It is said to return 5 l/100 km on the combined European cycle, with CO2 emissions of 119 g/km.

The first car to be fitted with the new Kappa engine will be the new i10 city car. However, Hyundai SA has said units destined for the local market are not be equipped with the new engine.

Perhaps we'll get a first taste of the engine when the Getz replacement i20 is launched here in 2009.
