Description devices motor G4KH 2.0 turbo
In 2010, the American versions of the Sonata and Optima sedans, as well as the Sportage 3 crossover, debuted a 2.0-liter Theta II turbo engine with GDi type direct fuel injection. By design, it is quite typical for the series, it has an aluminum block with cast-iron liners, a 16-valve cylinder head without hydraulic lifters, a Dual CVVT phase control system on both shafts, a timing chain drive and a balancer shaft block combined in one housing with an oil pump.
Engine number G4KH is located in front, at the junction with the gearbox
The first generation of these engines was equipped with a Mitsubishi TD04HL4S‑19T‑8.5 turbocharger, had a compression ratio of 9.5 and developed 260–280 horsepower and 365 Nm of torque. The second generation of internal combustion engines appeared in 2015 and featured an E-CVVT intake phase shifter, a compression ratio of 10, and a slightly simpler Mitsubishi TD04L6‑13WDT‑7.0T turbocharger. The power of such a unit has decreased to 240 - 250 horsepower and 353 Nm of torque.
Fuel consumption G4KH

Disadvantages, breakdowns and problems of the G4KH engine
These turbo engines are very demanding on the quality of the oil and the procedure for replacing it, otherwise the risk of cranking the liners on a run of about 100 thousand kilometers is extremely high. Even in services, they sin on an unsuccessful block of balancers combined with an oil pump: due to the rapid wear of its liners, the pressure in the engine lubrication system decreases.
The second generation units responded to the company for the replacement of the E-CVVT phase regulator and our modification of the Optima GT also fell under it. The problem was most often solved by installing a new cover, but in advanced cases it was necessary to change the entire assembly.
The units of the first generation did not have oil nozzles and they have scuffs, but most often the cause of oil consumption here is the banal ellipse of the cylinders. The rigidity of the aluminum block is low and it quickly leads to overheating.
As in any ICE with direct injection, the intake valves are quickly overgrown with soot. The timing chain also serves relatively little, the temperature sensor often fails, various air pipes constantly burst and oil leaks through the oil seals occur.
The manufacturer claims the resource of the G4KH engine is 200 km, but it also serves more.
