Hyundai’s 1.0-litre Kappa Turbo engine meets Euro6 standards

Added in: Hyundai


Hyundai first showcased the new Kappa 1.0-litre T-GDI engine at the 2014 Paris Motor Show. The Kappa 1.0-litre T-GDI is a high performance downsizing engine which could replace larger displacement natural-aspirated engines offering high fuel efficiency and low CO2 emission. The 998 cc three-cylinder unit is based on the established Kappa 1.0-litre MPI engine, carrying various enhancements and new technologies, including direct gasoline injection and a small, single-scroll turbocharger. The 1.0-litre T-GDI engine produces 120PS (88.1kW) and peak torque of 17.5kgfm (172Nm) and will enhance Hyundai’s engine line-up in 2015.

The new engine comes with an electronically-controlled waste-gate to improve low-end torque and transient response with better fuel economy by reducing pumping friction. The unit features a six-hole laser-drilled GDI injector, high pressure fuel supply system of maximum 200 bar, securing clean combustion and improving fuel economy and emissions to fulfill Euro6 emission standards.

It uses a split-cooling concept to manage different temperatures in the cylinder head and block area. The cylinder block is heated up quickly for lower friction and more efficient run, while the cylinder head operates at moderately low temperatures to suppress knock tendency hence improve fuel economy. The exhaust manifold is integrated within the cylinder head which efficiently cool down the exhaust gas temperature using the cylinder head water jacket around the exhaust port. These efforts result in faster warm-up reducing real-world fuel consumption and emissions.
