Hyundai Motor is showcasing two new turbocharged petrol direct injected (T-GDI) engines at the Paris Motor Show 2014. Both engines – 1.0-liter and 1.4-liter units which are part of a new generation of engines from the Kappa family – meet growing demand for small capacity, turbocharged engines to reduce fuel consumption and CO2 emission without compromising on driving pleasure.
New 1.0-liter T-GDI to premiere in new generation i20 in 2015
The new Kappa 1.0-liter T-GDI is the first of a new generation of small turbocharged petrol engines. The 998 cc three-cylinder unit is based on the Kappa 1.0 liter MPI engine, carrying various enhancements and new technologies, including direct petrol injection and a small, single-scroll turbocharger.
The 1.0 liter T-GDI engine, which was developed at Hyundai’s European Technical Centre in Rüsselsheim, Germany, is able to produce up to 117 hp and 172 Nm of torque and will enhance the New Generation i20 engine line-up in 2015.
The new engine comes with an electronically-controlled waste-gate to optimize flow and improve low-end torque and throttle response. The unit features a six-hole GDI injector, pressured to 200 bar, securing a clean combustion and improving fuel economy and emissions to fulfil Euro 6c emission standards, three years ahead of their introduction in 2017.
It uses a new split-cooling concept to manage different temperatures in the cylinder head and block area. The cylinder block is heated quickly for lower friction and more efficient run, while the cylinder head is operating at lower temperatures to optimize injection and combustion. To keep the engine unit as small as possible, the exhaust manifold is integrated within the cylinder head and can therefore be cooled efficiently using the cylinder head water cooling system. These efforts result in faster warm-up of the catalyst and ultimately in reduced real-world fuel consumption and emissions.
New Kappa 1.4-liter T-GDI engine
The second engine to be showcased at the Paris Motor Show 2014 is the Kappa 1.4-liter T-GDI unit. This newly developed 1352 cc four-cylinder turbocharged petrol engine is significantly lighter than its predecessor, the Gamma 1.4-litre engine. At 87 kg, the engine’s base weight has been reduced by 14 kg compared to the Gamma 1.4-liter unit. As well as being lighter and smaller, it features improved efficiency and power.
The new 1.4-liter T-GDI engine incorporates a high-pressure single-scroll turbocharger integrated within the exhaust manifold to improve operational efficiency. The relocated and re-engineered turbo means throttle response time and low-end torque have improved. The new design injects fuel directly inside the cylinder.
Showcased in the i30 CNG concept car displayed on Hyundai’s Paris Motor Show booth, the Kappa 1.4-liter T-GDI engine provides 115 hp in CNG mode, delivering 206 Nm of torque. The CO2 emissions of the i30 CNG concept car are 87 g/km, which already meet Euro 6c emission standards.
