Delphi Technologies has announced that its DFI 21 fuel injector – with a diameter of just 1mm – for medium- and heavy-duty diesel application is now in pilot production.
The DFI 21 injector can provide substantial improvements in emissions, fuel economy and refinement while maintaining exceptional reliability, the company said. It was announced as a development concept in 2016 and, following business wins in Europe and the US, will enter volume production in 2021.
“Reducing engine-out emissions gives engine designers much greater flexibility in their aftertreatment strategy, with some significant potential cost savings for the vehicle manufacturer and the vehicle operator,” said Delphi Technologies product engineering director James Kewley. “For example, DFI 21 could allow simplification of exhaust aftertreatment and a reduction in SCR fluid consumption, which can be of significant value to long-distance truck fleets.”
Andrew Davis, corporate communications director at Delphi Technologies, added that he sees more opportunities coming for the use of smart electrification in commercial vehicles in the coming years. “You will see increasing use of electrification to support auxiliaries,” he said. “For example, if a driver is parked up overnight running his fridge, heater, tv, air con etc, he isn’t going to want to have his engine running. I think smart electrification is going to increase.”
