Characterisation of the wall film development in port fuel injection (PFI) motorcycle and car engines is very important in achieving higher performance, lower emissions and better fuel consumption. As part of an on-going research programme, an in-house system was developed based on the Laser Induced Fluorescence (LIF) technique to allow the accurate measurement of the fuel film thickness in a simulated intake port, complemented by visualisation of the film development using high speed video imaging. Two fuels have been investigated: iso-octane doped with 5% (v/v) 2,3-hexanedione and conventional gasoline. Parametric studies have been carried out by investigating the effect of injection duration/quantity, air velocity and port backpressure. Representative data on the characteristics of the fuel film for the two examined fuels are presented, followed by discussion of the results and conclusions.
