DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the new multi-
hole injectors have been optimised for
torque, power output, fuel consumption,
emissions and ef ficient combustion.
With direct injection, the engine manage-
ment system regulates injection timing
individually for each cylinder as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and fuel economy. The system first dif ferentiates

bet ween driver inputs that t ypify normal,
everyday driving and those inputs
that demand maximum performance.
The electronic engine management
system then seamlessly adapts valve
operation to the prevailing conditions.
This results in instant acceleration,
extremely smooth running and an
extraordinary level of tractive power,
but with a comparatively low level of
fuel consumption.
For faster heating of the catalytic converters
after a cold start and optimum torque in
the upper load range, up to three injection
pulses take place per combustion cycle.
DFI improves the internal cooling of

the combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression
ratio, which helps to deliver more output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system

and emissions are monitored by the
Lambda sensors, thus helping to protect
the environment.
VarioCam Plus System.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake
camshafts and switching the lift of the
intake valves.
