Viscosity variation of diesel and marine distillates
Viscosity variation of diesel and marine distillates
(OP)
Two parts to this question:
I understand that injector manufacturers need to be able to rlate performance unde test to viscosity or control the viscosity which does imply that there may be some effects during operation, but how significant is it?
- by how much can viscosity vary between different batches of diesel and marine distillates, marine gas oil? I see from data I have that marine distillates DMX and DMA have maximum viscosities quoted at 5.5cst and 6 cst (at 40degC) but that isn't to say they won't be much less on occassion.
- how does this affect engine efficiency?
