Electronic commutation fuel pump

  • 06-Dec-2010 04:27 EST


Continental's electronic commutation (EC) fuel pump improves vehicle energy consumption and reduces CO2 emissions in gasoline, diesel, flex-fuel, or any other tank fluid. Featuring a brushless design, the in-tank fuel pump improves lifetime by more than 50%, claims the company, while improving energy use by as much as 70% when compared to conventional uncontrolled fuel pumps and by 10% over dc demand-regulated pumps. Additional benefits of the EC fuel pump include reduced CO2 emissions by 0.3 g/km in gasoline engines and by 0.5 g/km in diesel engines when compared to demand-controlled dc motors; increased durability and lifespan due to on-demand performance, compared to conventional uncontrolled fuel pumps that run at full speed 100% of the time; robust design that allows EC pumps to handle variations in fuel grades, including E100; and when combined with electronic controls, power and flow adjustments are made based on driving situation.
