The exhaust camshaft is driven by the intake
camshaft in connection with a gear drive
mechanism. The drive gearwheel is split in two
in order to avoid gearing noises caused by a
change in the driving tooth profile in
connection with a change in load. A disc spring
turns the two halves of the gearwheel in
opposing directions (functional principle
similar to dual-mass flywheel) so that both
tooth profiles of the exhaust gearwheel always
rest on the intake gearwheel under all load
conditions.
