That’s got to be good news for those who’ve been trying to follow their nonsense advice
Remember when Kia/Hyundai first came to the uk with their cheap tat and worked hard to climb the ladder to become the what they are anf gain a “cult” following. Its in their interests to sort the problem as soon as, or they risk falling down that ladder.
Is it Kia/hyundai’s fault though, they aren’t the only ones who use direct inject engines or is partly down to manufacturers forever chasing the latest emission laws…..
So GDI engines are becoming more popular due to the regulations to reduce CO2 emissions to satisfy the likes Euro 6. 6.2 etc.
The flip side of that is a GDI engine has a higher emission of particulate matter than a port fuel injection (think multi point fuel injection) petrol engine. The GPF is therefor needed to control the particulate matter emission, making the cars cleaner, therefore meeeting the lates EUro regulations. Its worth saying some manufactures use both port and direct injection on ther engines.
That said there are disadvantages to the GDI engine, such as high cylinder temperatures and pressures is released into the crankcase which over time causes oil to vaporize, which causes oil droplets, to coat the intake valves. A GDI engine does not spray fresh fuel onto intake valves. Overtime this causes carbon to build, sludge and burnt on fuel deposits to form on the pistons and valves. Good oil quality is an important factor with direct engines.
Direct petrol engines are also surposed to save fuel. I guess Kia/Hyundai got that wrong, A GDI engine is also said to be more powerful than an equivulent port inject. Guess they got that wrong to!
