Delphi Automotive Systems (NYSE: DPH), with its recent diesel business acquisition, is uniquely positioned with a full line of diesel engine management systems to respond to the rising popularity of diesel engines worldwide. To date, more than $2 billion has been booked over five years for the diesel common-rail direct-injection system, said Guy C. Hachey, president of Delphi Energy & Chassis Systems. Of that total, $800 million has been booked since Delphi acquired the diesel business in January, Hachey said.
