Here is a thought. On Peugeots people get the dreaded and annoying injector rattle. If people are correct in saying that this is because the injectors can't close fast enough and spray in too much on the pre-injection then that means you wouldn't want a high cetane rating surely?
I mean the higher the cetane the faster it ignites. However if it is igniting a large explosion on the pre-injection due to injector problems then that would significantly raise the cylinder pressures during the upwards stroke. If you had a much lower cetane it would delay the pre-injection explosion possibly back to the original explosion timing position?
