load. The partial load cam has
been developed with regard
to fuel economy optimization
and smooth running. The par-
tial load cam reduces both the
valve timings adapted for this
purpose and the intake valve
stroke. Furthermore, the intake
cams for the left and right in-
take valve differ in stroke and
angle position when the par-
tial load cam is activated. This
causes a staggered opening of
the two intake valves, which
have different widths. The ad-
vantage is that the fuel-air mix-
ture flowing into the combus-
tion chamber is more strongly
swirled and more effectively
burned. Overall, this results in
optimal fuel efficiency and no-
ticeably improves the smooth-
ness of running. The full load
cam is optimized for perfor-
mance and releases the max-
imum intake valve stroke. In
order to vary the valve timing
and the valve stroke, the in-
take camshaft is shifted axially.
For this purpose, the pins of
an electromechanical actuator
mesh with a shift gate on the
intake camshaft. This allows
for the actuation of the intake
valves depending on load and
motor speed and, as a result,
an uncompromising symbiosis
of performance and low fuel
consumption.
ADAPTIVE HEADLIGHT
with Adaptive Lights
How do the adaptive
headlights work?
The standard installed dimming
unit in the headlight consists
of two reflectors that gener-
ate low-beam headlights us-
ing LED. Ride height sensors
at the front and rear wheel
suspension provide data for
continuous headlight range
control. Thanks to the pitching
compensation, the light always
illuminates the optimal, preset
area when riding on straight
stretches of road, regardless of
the riding conditions and load
status. Using Adaptive Head-
lights, the dimming unit addi-
tionally rotates around an axis,
depending on the angle, and
compensates for the angle of
roll of the vehicle. The angle of
rotation is 70° (± 35°).
In addition to the pitching com-
pensation, therefore, the low-
beam headlight is adjusted to
compensate for the lean angle
during riding. Both movements
are overlaid so that a highlight
in the curve results. This re-
