The intake process of a 4-stroke, 4-cylinder boxer spark ignition engine with port fuel injection (PFI) for aircraft applications is analyzed. For such a study, a set rig has been set up and several measurements have been carried out at different RPM under full load conditions to estimate volumetric efficiency. Based on such experimental results, 3-D CFD simulations have been carried out to study both the intake process and the compression stroke from Intake Valve Opening (IVO) up to the Start Of Ignition (SOI). The computed volumetric efficiency is evaluated and compared with experimental results at different RPM.

Abstract
The intake process of a 4-stroke, 4-cylinder boxer spark ignition engine with port fuel injection (PFI) for aircraft applications is analyzed. For such a study, a set rig has been set up and several measurements have been carried out at different RPM under full load conditions to estimate volumetric efficiency. Based on such experimental results, 3-D CFD simulations have been carried out to study both the intake process and the compression stroke from Intake Valve Opening (IVO) up to the Start Of Ignition (SOI). The computed volumetric efficiency is evaluated and compared with experimental results at different RPM.File in questo prodotto:
