An engine test has been developed which differentiates the cleanliness characteristics of two-cycle lubricants. This test procedure utilizes an air-cooled Yamaha motorcycle engine and is run using a cyclic operating procedure for 20 hours. Test severity in the ring belt area is controlled by combustion chamber temperatures and fuel consumption rates.
Utilizing these techniques, programs were conducted which were directed to the development of improved two-cycle lubricants using the present BIA TC-W(1, 2)* reference oil as a baseline. The effects of various parameters of lubricant formulation were determined including concentration effects of the additive presently used in the TC-W reference, bright stock content, and the use of supplementary additives.
