Intake Valve Deposit Control - A Laboratory Program to Optimize Fuel/Additive Performance 892115

With increased attention now being focused on controlling fuel-related intake system deposits, the need for high-performance gasolines has intensified. Certain import and domestic automobile manufacturers have expressed concern that some of today's gasolines formulated to prevent fuel injector deposits may have a negative effect on deposit control in other areas of the fuel intake system. This paper covers the development of a laboratory engine test procedure to evaluate the impact of fuel additive technology on intake valve deposits. Additive formulation has been optimized providing outstanding control of intake valve deposits with no compromise in PFI deposit control.
