The 2.4-liter Hyundai-Kia G4KJ or 2.4 GDi petrol engine has been produced since 2009 and is installed on such popular models as Optima, Sonata, Santa Fe, Sorento, and Sportage. This unit is distinguished by the presence of a GDi direct injection system and a block of balancing shafts.
In 2010, a new 2.4-liter engine of the Theta II line, equipped with GDi direct fuel injection, debuted on the American versions of the Hyundai Sonata YF and Kia Optima TF sedans. In all other respects, this is a typical power unit of the line with an aluminum cylinder block, cast-iron sleeves, an open cooling jacket, CVVT phase regulators on two shafts, a 16-valve head without hydraulic compensators, a timing chain and VCM and VIS systems in the intake. Like many large displacement 4-cylinder engines, it is equipped with a block of balancer shafts.
This engine has been constantly upgraded and the main innovations are the appearance of oil nozzles for cooling the pistons and the E-CVVT phase regulator on the intake camshaft.
