Abstract
This paper presents the results of studies on the mechanism of intake valve underside deposit formation in recent model passenger car engines. The effect of fuel and lubricant composition on deposit formation, as well as the influence of engine design and operating conditions, are described. High-speed motion pictures have been made showing the phenomena occurring in the intake underside area during various types of engine operation, and the conclusions reached from this study are also presented. Techniques for automatically operating laboratory engines in a manner giving intake valve deposits representative of those obtained in field test vehicles have been developed and are described.
