Abstract
To reduce the time associated with fuel additive testing, a quick, reliable and repeatable screening test was necessary for the evaluation of intake system deposit levels. The additive development process has also shown certain additive packages to result in intake valve stickiness at low temperatures. A successful additive screening procedure was developed using a portable generator set. This paper describes an 80 hour test in which different additives and dosage levels can be evaluated for both intake valve deposit and stickiness levels. Test results were comparable to those found in automobile testing.
