Studies of fuel injection into a rapid compression machine
An opposed-piston rapid compression machine has been fitted with a single-shot diesel injection system. The ignition of fuel sprays has been studied over a range of experimental conditions, using decane or blends of decane with lower cetane quality aliphatic and aromatic basestocks. It is shown that at low temperatures, the cetane number is insufficient to characterize the ignition quality of fuels with significant aromatic content. The performance of ignition-promoting additives has also been examined. Their effectiveness is shown to depend on physical conditions including temperature and the duration of ignition delay. Their behavior can be qualitatively understood in terms of a simple two-stage process leading to ignition after fuel injection. 8 refs.
