    Q. It is suggested that CRD can't handle dirty fuel as well as a mechanical pump diesel, but can anyone put this into context? Is it at the injector that the containment is likely to cause problems? Or elsewhere in the system? What size particles are we talking about that will block these choke points? How different is the size limit on particles in a mechanical pump?

    Yes it was those people who complained when cars changed from magnetos, manual mixture and timing controls and went to distributors with vacuum and mechanical timing control.

    its never really the technology, its almost always the price point and QC that the OEM company chooses to implement. Yes sometimes they make silly little mistakes, but really it just comes down to $$$ and what they feel the market is and how the vehicle should perform short and long term.

    I tell you, you can't beat those solid rubber tyres and wooden spokes.

    This may perhaps not be the right thread, but here goes with a question:

    Modern diesel engines have gone to common rail and electronics to be more efficient and cleaner.

    But:
    - My 20yo TDi300 gets 9 or 10L /100
    - My 10yo TD5 gets 10 or 11L/100
    - My new PUMA gets 11 or 12L/100

    How come we've got all this newer tech stuff but the fuel efficiency is going in the other direction? What am I missing here? Power probably....


    Cheers
    David
