Table 1 Matrix of experimental test cases. The same flow conditions and needle lift have been applied for the two diesel blends examined, namely a conventional multi-component diesel sample, and a non-Newtonian counterpart treated with Quaternary Ammonium Salt (QAS) additives. The last two columns of the table correspond to the pressures measured at the orifice inlet (pinj) and outlet (pback), respectively. CN values reveal that well-established cavitation conditions should be expected within the orifice.
