and defects that may occur in the
exhaust and fuel systems and
notify the driver immediately. This
also prevents increased pollutant
emissions and unnecessary
fuel consumption. to a cylinder or piston at high
engine speeds and loads.
The on-board diagnostics ensure
timely detection of any faults
Since cylinders never all work
under exactly the same
conditions, the ignition point is
shifted individually, as and when
necessary. This prevents damage
consumption and emissions,
whatever your driving style.
Another important function is the
cylinder-specific knock control,
which compensates for different
fuel grades added to the engine.

standard. Moreover, it regulates
all engine-related functions and
assemblies (see diagram). The
results: optimum performance
and torque with reduced fuel The EMS SDI 6.1 electronic
engine management system
ensures optimum engine perform-
ance at all times. In particular,
it evaluates the signals of the
