If I=(I1,...,Id) is a random variable on [0,[infinity])d with distribution [mu](d[lambda]1,...,d[lambda]d), the mixed Poisson distribution MP([mu]) on is the distribution of (N1(I1),...,Nd(Id)) where N1,...,Nd are ordinary independent Poisson processes which are also independent of I. The paper...

A detailed mathematical model of a direct-acting prototypal piezo-injector has been developed to help experimentation, design and component optimization. The thermo-fluid dynamics of the hydraulic circuit components, including the injector feeding pipe, injector drilled pipes and nozzle, was...

An innovative hydraulic layout for high-pressure fuel injection systems has been developed. The rail has been removed from the high-pressure circuit of standard Common Rail injection apparatus in order to have: reduced production costs, easy installation on the engine and a fast dynamic response...

The prediction capability of an advanced Common Rail (CR) piezoelectric injection-system mathematical model has been upgraded and applied to the analysis of transient flows inside injectors. The predicted time histories of the sac-, delivery- and control-chamber pressures, of the pilot- and...
