Abstract
Control of inlet valve deposit (IVD) formation in port fuel injected (PFI)
gasoline spark ignition (SI) engines has been an on-going concern due to the
deleterious impact that this material can have on engine performance (power,
acceleration times, drivability and fuel consumption). However, decoupling the
effects of IVD formation from the multiplicity of other changing engine
parameters whilst quantifying the impacts on engine behavior has remained a
challenging task to accomplish. A dedicated experimental methodology is
presented that has been specifically designed to address this issue. It
successfully decouples and quantifies those engine performance impacts that are
attributable to IVD formation. Results are presented demonstrating the
deleterious impact of IVD formation on fuel consumption in a PFI SI engine.
