A 12 valve, 4cyl engine like that of Santro has 3 valves per cylinder. My question is, for each cylinder 1 valve is for exhaust and 2 for intake or vice versa???Why not 1 for intake and 1 for exhaust is enough, and total 8 valves???
let the experts answer u.......i also need the answer
2 for intake and one for exhaust. 8 valves for intake and 12 in total.
he just wants to ask why their r 2 for intake and 1 for exhaust..
In three valve per cylinder set up Exhaust valve usualy more bigger in size as of intake valves.
