So,
I had a restless night subconciously thinking about the last post about the pumps being “equal” with the Bosch quoted fuel delivery of 70mm³/stroke.
That cannot be accurate, surely, as there are wide physical permutations to the pump itself and delivery of the fuel e.g. pumphead range of 8mm to 12mm, varying nozzle sizes and at what rpm?
1mm³ = 1µL or 0.000001L or 1e-6L of diesel per stroke, so we have a volume per stroke.
The density of diesel varies, but 0.85 kg/L as an average value for D2 pump diesel, so 1 kg x 1 L/0.85 kg/h = 1.18 L/h)
0.85 / 0.00007L/stroke = 0.0000595 kg/stroke of pump diesel .... which is "Bosch rubbish".
