Delphi’s multec® diesel common rail system helps new Volkswagen Polo BlueMotion achieve record low CO2 emissions and fuel consumption
Latest evolution of Delphi’s solenoid injector and next generation Delphi pump help vehicle reach 87g/km of CO2 emissions, fuel consumption of 3,3l/100km (71mpg) without performance compromise.
Cleanest car in its class; voted 2010 World Car of the Year by international automotive journalists.
(firmenpresse) - Delphi Corp. and Volkswagen have developed one of the “greenest” diesel systems ever produced with the new 3-cylinder VW Polo BlueMotion. This allows the automaker, a recognized leader in diesel-powered passenger cars, to offer consumers a vehicle with exceptionally low CO2 emissions and fuel consumption, while still delivering exceptionally refined powertrain performance. After more than a year of co-development with Volkswagen, Delphi, a global leader in diesel engine management systems, is supplying its Multec® Diesel Common Rail System for the new 1.2-liter, 3-cylinder Volkswagen Polo BlueMotion. “Our customers are downsizing their engines to meet stringent CO2 requirements. The new Volkswagen 3-cylinder Common Rail diesel engine allows Delphi to demonstrate the great potential of our solenoid-based fuel injection system technology,” said Michael Gassen, general director, Delphi Powertrain Systems and Delphi Europe, Sales & Marketing. “This is Delphi’s first diesel Common Rail program with Volkswagen and it is on a vehicle that is now the most economical five-seater with the lowest emissions and the 2010 World Car of the Year. This is an excellent match for our technology.”The common rail system on VW Polo BlueMotion includes the latest evolution of solenoid type diesel common rail injector technology with Delphi’s next generation DFP6 fuel pump. This combination allows for just 87 g/km of CO2 emissions.
“Delphi’s new common rail system provides significantly improved fuel delivery control, extended multiple injection capability, enhanced spray atomization and air mixing,” said John Fuerst, general manager, Delphi Diesel Systems. “The system in this vehicle can deliver up to six injection events per combustion cycle, which translates into a very smooth combustion process and therefore lowers the NVH levels.”
As well as optimized combustion, the injection efficiency of the system is improved through reduced parasitic losses, reduced component mass, improved energy consumption and hydraulic performance. Because of this, Delphi’s common rail system will suit future generations of downsized engines in a range of vehicle classes.
Delphi’s next generation high pressure pump:
The pump is designed to simplify packaging and reduce weight while providing 2,000 bar maximum rail pressure. Its design combines a relatively small specific capacity of up to 0.42 cc/rev with the capability to run at engine speed to provide flexibility for efficient utilization on a range of engine sizes up to 2.2 liters. This is achieved by an approach that includes a new compact hydraulic head design which helps to improve the volumetric and mechanical efficiency enabling a potential reduction of engine CO2. The new concept is much stiffer than the previous generation head, with Delphi’s integrated inlet valve assembled directly into the head and a forged high-pressure outlet, which incorporates the outlet valve and helps to achieve reduced stress and offers further room for extension to rail pressures higher than 2,000 bar.
