Siemens VDO Automotive Supplies Jaguar S-Type 2.7l V6 Twin Turbo Fuel Injection and Engine Management System

AUBURN HILLS, Mich., June 24 -- The Jaguar S-type is celebrating its comeback with a new look and, for the first time, is being marketed with a diesel engine under the hood. The injected compression ignition engine unleashes its propulsive power in every gear and is enabled by a Siemens VDO Automotive piezo-based injection and engine management system that provides driving pleasure that is felt -- not heard.

The Siemens VDO Automotive piezo injectors in the common rail fuel injection system generate pressures up to 1650 bar and are breathtakingly precise. Their extremely quick and exact control allows fuel to be injected into the cylinders with unprecedented repeatability. A pump controlled by volume flow and pressure supplements the system and contributes to the positive performance balance of the engine. In tandem with multiple injection and high pressure, piezo actuation not only runs quietly, but also reduces fuel consumption and exhaust. Working harmoniously, the system translates into high performance, low fuel consumption and minimum decibels.

"The fuel injection system offers manufacturers an ideal basis for finely tuning the overall system," said Siemens VDO Automotive Director of Diesel Systems North American Julian Dench. "Behind the magisterial calm is a carefully calibrated hardware and software package that Siemens VDO Automotive has incorporated into a 32-bit engine control unit for the new Jaguar."

The new Jaguar powerplant carries forward none of the old monikers associated with traditional diesel engines. The near friction-free interaction of the controlled engine and vehicle functions creates only a discrete diesel noise and the vibration-suppressing engine design cultivates the smoothness of the compression ignition engine. A new engine block material is used that was produced in a developmental alliance between Ford, Jaguar and PSA.

After the great success of Jaguar's V6 twin turbo engine in the sports sedan, other models from European manufacturers equipped with Siemens VDO Automotive's high-performance diesel engine and technologies will be entering the market over the course of the year.

"As a pioneer of piezo diesel injection, Siemens VDO Automotive was the first supplier to start worldwide production of piezo fuel injection valves in 2000," said Dench. "As of today, the company has supplied more than five million diesel injectors."

In preparation for the strict Euro 5 standard taking effect in 2008, Siemens VDO Automotive engineers already have designed the next generation of piezo injectors. The new system, with an injection pressure of around 1800 bar, should undergo initial series production in 2006. In the coming years, the company plans fuel injection systems with even higher pressures.
