center
The cylinders are offset from the center of the crankshaft.
PISTON
ZK602586AA00
Piston off set 0.5 mm
Front mark
Special aluminum alloy is adopted to improve heat efficiency and
achieve lower weight.
That contributes to higher engine performance and better fuel
economy. Piston pinhole center is offset by 0.5 mm from piston
center towards the thrust side.
Out side surface of piston skirt has striation-like finishing better
oil holding ability (and superior durability against scuffing.)
