a very good read,
ok onto your document
funny it doesnt mention ANY where in the entire document any measurement of common rail injectors, just the pumps nor does it cover unitary injectorsOriginally Posted by attached link 39130.pdf
have a crack at the wear factors on the injectors and the pumps in appendix 11 12 and 15 and remember that thats only a short term test thats been conducted. as per para 4.4 500 hours of service. pay particualr attention to the deviation from norm patterns on the injector pins... and thats after ONLY 500 hours (unknown for the heavily contaminated fuel, it didnt make the whole test) And thats only for standard low pressure injection.
and..
hmm filter blockage, sounds like a filter doing its job, time to change the filter, you know, maintenance wise because the filter has done its job in stopping bad stuff from hitting the injector pump and injectors.Originally Posted by attached link 39130.pdf
the problem with the filtration is easily solved if you dont mind a fairly large multi packet solution... with current technology a one package setup that provides a realistic long term low maintenance solution is not currently achievable.
My filtration system utilises filters intended to run a 250+hp heavy transport diesel and Im only pushing a piddly 50ish HP engine yet I still change filters at the same interval as the big diesels... try finding room for that stuff in something like a D2/3/4, new toyota, jeep, mitsu.. take your pick.
A good re-read of a document Ive read before.
and EN 590 permits a MAXimum of up to 7% bio content in diesel it does not stipulate that it MUST contain 7% biodiesel...
Mercedes, Ford and Volvo still stipulate that their common rail diesel engines are not designed to run with any bio content.
