Abstract
Process for the quantitative determination of gasoline film deposited on the intake manifold of an engine with controlled ignition, which comprises the following steps: PA1 a) feeding of a first set of injectors (I) with a first fuel selected from those which do not leave deposits in the feeding manifold; PA1 b) opening of the second set of injectors (II) fed with a second fuel to be tested, until an equilibrium stage of the air/fuel ratio equal to that of step (a) is reached; PA1 c) calculation of the mass of fuel film by integrating the difference in the flow-rate values measured in step (b).
