2011 PORSCHE 911 CARRERA compression ratio

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. 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.

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.
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 seamlessly adapts valve

Weight is calculated in accordance with the relevant EC Directives and is valid for vehicles with standard specification only. Optional equipment increases this figure. The figure given includes 68 kg for the driver and 7 kg for luggage.2) Data determined in the NEDC (New European Driving Cycle) in accordance with the Euro 5 (715/2007/ EC and 692/2008/ EC) measurement method. The figures do not refer to an individual vehicle nor do they constitute part of the of fer.
They are intended solely as a means of comparing dif ferent t ypes of vehicle. You can obtain further information about individual vehicles from your Porsche Centre. Fuel consumption calculated for vehicles with standard specification
only. A vehicle’s fuel consumption and CO
2 emissions depend not only on its ef ficient use of fuel but also on driving st yle and other non -technical factors. Actual consumption and per formance may var y with items of optional equipment.
