    Vehicle : Vauxhall

    Trim : very

    Engine : Z19DTH

    Year : Nosey

    Default How about solenoid valves!?

    We now have electrically controlled fuel injection via solenoids, so surely the next step is to replace all the valves with said and get rid of cam shafts and just use a crank angle pickup in conjunction with an rpm sensor to allow an ECU to calculate optimum opening times.

    Does anyone know if any manufactures are working on this?

    ??????

    Why would anyone want to develop this?? The thermal load that the solenoids would have to take would make this a no-brainer..there is no advantage to running them electronically IMO..

    Cummins tried it on heavy commercial diesels about 12 years ago, it never got past initial development testing.

    Interesting mate. So you were based at Daventry?

    Cummins qualified myself, but only in the gas engines.

    QSV91G is based off the diesel engines anyway. 16 and 18 cylinders as developed closely with Wartsila until they lost love with each other.

    Gas engines are fun, our company operates all the gas engine prototypes in the UK pretty much except Jaguar in Coventry.

    Many a day has been spend overhauling one of them. Good engines. Though with the new projects we are doing we are heading towards Yanbacker (sp).

    No I was based up here in the North East when Darlington had it's own engine plant.
    Went on a good few trips to Omaha in the states though.
