Did you know the 1.6L 110hp G4ED Alpha II engine in the 2006-2010 Hyundai Accent (like my Accent), 2006-2011 Kia Rio, 2002-2011 Hyundai Getz, and 2004-2007 Kia Cerato/Spectra has a Timing Belt AND a Timing Chain?
Pics from some Autodata screenshots I found online:
Pretty unique engineering as I’ve only ever known cars to have one or the other! The Alpha II has a belt connecting the crankshaft and one camshaft while a separate timing chain links that camshaft with the second one! The timing chain is contained within the head and is specced for the life of the car while belts are recommended to be changed every 90,000km.
Definitely a DOHC layout I’ve not heard of before! Maybe it’s more common than I know and I’m crazy...?
