Camshaft adjustment system
The gas exchange processes in the engine's combustion chamber exert a significant influence on output, torque
and pollutant emission. The camshaft adjustment system allows these gas exchange processes to be adapted to the
engine's relevant requirements.
This is carried out by changing the valve opening and closing times, depending on the engine speed, with the aid
of the inlet camshaft. In this case, the torque is increased in the lower to medium engine speed range, whilst output
is raised in the upper engine speed range.
Camshaft adjustment additionally improves internal exhaust gas recirculation.
Adjustment equates to a crank angle of 22° in the "advance" direction.
