2013 PORSCHE 911 CARRERA compression ratio

DFI delivers fuel directly into the combustion
chamber with millisecond precision. The
spray and cone angles of the multi­hole
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 improves the combustion process
and fuel economy. vailing 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 mix
­
ture 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 emis ­
sions are monitored by the Lambda
sensors.

VarioCam Plus System.
VarioCam Plus is a two ­in ­one engine
concept for adjusting the intake cam ­
shafts and switching the lift of the intake
valves.
The system first dif ferentiates bet ween
driver inputs that typify normal, everyday
driving and those inputs that demand
maximum performance. The electronic
engine management system then seam ­
lessly adapts valve operation to the pre ­
