Continental has developed a direct-acting piezo injector with closed-loop needle control. It hopes OEMs will use the technology in diesel cars to meet 2014's Euro 6 emissions standards, but its first series application will be in a light commercial vehicle next year. It is not the only supplier with direct actuation of the needle, which improves accuracy compared to injectors with hydraulic transmission. Delphi, Bosch and Denso also have this technology.
