A few years ago, I read about auto radiators being coated with a catalytic material so that as air was pulled through the radiator after it had warmed up, organic materials in the air would be converted over to CO2 and H2O. This got me to thinking about intake valve deposits on the intake valves of GDI vehicles. Would it be possible to coat the intake valves with a similar catalytic material so that when the engine reached operating temps, the valves would be warm enough to destroy the deposits that form on the valve faces and stems? Obviously, if a radiator temperature of say 220 F works,the intake valves have to get at least that warm in an operating engine.
