Siemens VDO Automotive Technology Featured on Seven of Ward's 10 Best Engines

DETROIT--Jan. 1, 20052, 2005--Siemens VDO Automotive's engine management solutions are helping seven of Ward's 10 Best Engines of 2005 meet the world's most stringent exhaust emissions and fuel economy targets. The selection of celebrated power plants featuring some of the company's innovative powertrain technologies were today displayed at the Ward's "10 Best Engines of 2005" awards presentation and V.I.P luncheon held at the Renaissance Center's Ambassador Ballroom in Detroit.

The seven "Best Engines" showcasing Siemens VDO Automotive technology include, Chrysler Group's 5.7L Hemi Magnum OHV V-8 (300 C); Ford Motor Co.'s 4.6L SOHC V-8 (Mustang GT); General Motors Corp.'s 4.2L DOHC I-6 (midsize SUV); Acura's 3.5L SOHC V-6 (Acura RL); Infiniti's 3.5L DOHC V-6 (Infiniti G35 6-speed); and Audi's 3.2L FSI DOHC V-6 (Audi A6) and 4.2L DOHC V-8 (Audi S4) engines.

"Bringing powertrain innovation to market is a challenge we truly enjoy at Siemens VDO Automotive," said Siemens VDO Automotive President and CEO John Sanderson. "But bringing our global expertise to Asian, North American and European engine builders and helping them meet ever-increasing emissions targets is a value that distinguishes us from other companies."

Award-Winning Engine Applications

The General Motors 4.2L DOHC I-6, Infiniti 3.5L DOHC V-6 and the Audi 3.2L FSI DOHC V-6 and 4.2L DOHC V-8 engines feature the Knock Sensor. Advanced engines with high compression ratios, need to meet the requirement for lower fuel consumption. The Knock Sensor is designed to constantly measure structural vibrations in the internal combustion engine to continuously adjust the ignition parameters during operation. Siemens VDO Automotive's Knock Sensors are broadband sensors, which are increasingly replacing resonance sensors.

The Chrysler 5.7L Hemi Magnum OHV V-8 contains a vibration-welded air fuel module that integrates 26 previously independent components in one deliverable unit. It contains the integrated Electronic Throttle Control (ETC), fuel injectors and rail, emissions components and air cleaner housing and resonator to improve the fuel economy.

The Acura 3.5L SOHC V-6 engine helps cut down on fuel emissions with Electronic Exhaust Gas Recirculation (EEGR), a procedure in which a portion of the exhaust is introduced into the intake of an engine, primarily for NOx reduction (the reduction of oxides of nitrogen).

The Infiniti 3.5L DOHC V-6 not only incorporates the Knock Sensor into the engine to improve the environment, but it also incorporates the Barometric Absolute Pressure Sensor. The BAP Sensor is used for the engine control unit function requiring additional altitude compensation and ambient pressure measurement.

The Ford 4.6L SOHC V-8 features the company's Electric Vapor Management Valve (EVMV), which is designed to improve emissions and performance by controlling the amount of fuel vapor the engine recovers from the carbon canister and fuel tank.

In addition to the Knock Sensor, the Audi 3.2L FSI DOHC V-6 also utilizes Siemens VDO Automotive's Exhaust Control Valve (ECV) and Engine Control Unit (ECU) and Control System. The ECV controls the amount of exhaust gas recirculated through the engine in order to reduce emitted Nitrogen Oxides (NOx). The 32-bit ECU and Control System manages the direct injection of fuel in the engine.
