The new pump generation will be controlled by an electronic control unit, housed inside the flange of the supply module. "This contract underlines Continental's market leadership in fuel delivery system technology," said Markus Distelhoff, head of Continental Powertrain's Fuel Supply Business Unit.
Intelligent control saves between 60 and 70 percent of electrical energy compared to traditional constant fuel supply systems. In a 1.8 liter engine, this can mean a CO2 saving of 1.5 to 2 grams per kilometer.
"By introducing this product to the market, the Fuel Supply Business Unit can claim to be the pioneer of demand-regulated electronically-controlled pumps," explained Distelhoff. "The potential savings of two thirds of the pump's electrical energy shows just how much a sophisticated, demand-regulated fuel feed system can contribute."
Some of the benefits provided by the demand-regulated pumps are listed below:
• Integrating the unit reduces both assembly time and the space required in the vehicle.
• The time and cost of system integration is also significantly reduced because the design of the pump and the electronics supplied by Continental are already matched to each other, thus shortening total development time.
• In addition, less logistical effort is involved in procuring a single assembly, resulting in considerable overall cost benefits for the vehicle manufacturer.
• The short electrical connection between fuel pump and electronics within a single component inside the fuel tank safety area results in considerably better electromagnetic compatibility (EMC).
• Since there is no need for a cable with two plug connections, the system is more reliable, further reducing overall costs.
• Vehicle manufacturers have also recognized the particular benefits of brushless fuel pumps with electronics integrated into the flange.
