Kia says the engines embrace the growing automotive industry trend towards smaller capacity, higher efficiency units that consume less fuel and emit fewer emissions – while still delivering responsive performance.
Depending on the engine, features will include: DCVVT (dual continuously variable valve timing – for both intake and exhaust systems), high pressure direct injection (up to 200 bar through a six-hole injector), exhaust-manifold integrated low-inertia single-scroll or twin-scroll turbochargers, an air-guided inter cooler (with innovative ducting which doubles air flow and improves cooling performance), a separated wall exhaust manifold which reduces exhaust back pressure, enhanced oil injection to decrease piston temperature for improved durability, and tumble-enhanced intake ports for more efficient combustion.
Kia’s powertrain display features a three-cylinder turbocharged Kappa 1.0 T-GDi unit that develops either 100 ps or 120 ps – the same as the current four-cylinder unit and a 10-to-15 per cent fuel efficiency improvement, Kia claims. The new Kappa 1.2 T-GDi is a four cylinder turbocharged 1,248 cc unit which promises a similar performance to current 1.6-litre units, Kia says.
he Gamma 1.6 T-GDi has four cylinders. It is a 1,591 cc turbocharged unit that generates 204 ps and 265 Nm of torque. The new Theta-ll, 2.0 T-GDi is a turbocharged four cylinder engine, with a capacity of 1,998 cc and produces up to 245 ps.
