In this paper the behavior of an injection system with a rotative pump for reciprocating engines is investigated. Experimental investigations were carried out using a specially designed apparatus to monitor several parameters, such as pressure inside the different chambers of the apparatus, moving part lift, and injected fuel quantity. In addition, a predictive mathematical model, based on mass momentum conservation laws, was developed to simulate such behavior and to predict all the most important parameters of the injection system. The comparison between numerical and experimental results has been satisfactory, allowing a generalization of the model and extensive theoretical predictions of the system behavior.

In addition, a predictive mathematical model, based on mass momentum conservation laws, was developed to simulate such behavior and to predict all the most important parameters of the injection system. The comparison between numerical and experimental results has been satisfactory, allowing a generalization of the model and extensive theoretical predictions of the system behavior.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
