Improved performance – lower consumption Bosch provides gasoline direct injection to the new Ferrari California
· 200 bar injection pressure in combination with solenoid valves for the first time
· Bosch supplies complete injection system for the naturally aspirated engine
· Eight-cylinder engine with 107 horsepower per liter displacement
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 engine with 4,297 cubic centimeter engine displacement delivers 338 kilowatts (460 horsepower) at 7,750 revs per minute, 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 liter 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.
One injection system per cylinder bank
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.”
The special ownership structure of Robert Bosch GmbH guarantees the entrepreneurial freedom of the Bosch Group, making it possible for the company to plan over the long term and to undertake significant up-front investments in the safeguarding of its future. Ninety-two percent of the share capital of Robert Bosch GmbH is held by Robert Bosch Stiftung GmbH, a charitable foundation. The majority of voting rights are held by Robert Bosch Industrietreuhand KG, an industrial trust. The entrepreneurial ownership functions are carried out by the trust. The remaining shares are held by the Bosch family and by Robert Bosch GmbH.
