The launch
of the Ferrari California marks the Italian sports
carmaker's first production engine with direct gasoline
injection. Bosch supplies the complete V8 engine
injection system, which was developed in close
collaboration with Ferrari's engineers.
The California's engine with 4,297 cubic centimetre
engine displacement delivers 338 kilowatts (460 brake
horsepower) at 7,750 revs per minute, while the maximum
torque is 485 Newton meters at 5,000 revs per minute.
This is the first engine to feature solenoid-controlled
injection valves with an injection pressure of 200 bar.
Thanks to precise metering and optimum atomization of
the fuel through the HDEV5 valves, the combustion
process was improved considerably. The resulting 107
horsepower per litre of engine displacement is a
noteworthy power output for naturally aspirated engines,
and this with a considerably improved torque curve. At
the same time, direct fuel injection allowed consumption
and CO2 targets, which are also becoming increasingly
important for Ferrari, to be achieved with aplomb.
Another first in this V-type engine is that each
cylinder bank has its own fuel-supply system, with fuel
being delivered by two high-pressure pumps. The systems
are synchronized by two Bosch MED9.6.1 electronic engine
management systems.
In addition to the gasoline injection system, Bosch also
supplies hot-film air-mass meter, lambda sensors, the
ESP(r) premium braking control system, as well as a
number of sensors for the Ferrari California.
The Bosch Group
is a leading global supplier of technology and services. In
the areas of automotive and industrial technology, consumer
goods, and building technology, some 271,000 associates
generated sales of 46.3 billion euros in fiscal 2007. The
Bosch Group comprises Robert Bosch GmbH and its more than
300 subsidiaries and regional companies in roughly 50
countries. This worldwide development, manufacturing, and
sales network is the foundation for further growth. Each
year, Bosch spends more than 3 billion euros for research
and development, and applies for over 3,000 patents
worldwide. The company was set up in Stuttgart in 1886 by
Robert Bosch (1861-1942) as “Workshop for Precision
Mechanics and Electrical Engineering.”
