The Use of Time/Temperature Additive Release Package in the Automotive Lubrication System 780373
A system combining an oil filter with a supplementary time/temperature additive release package has been developed which provides a non-conventional but very effective means of maintaining the viscosity level in the operating engine. Simultaniously, the system introduces certain other additives important to the engine oil performance. Studies of this system have been conducted to better understand the additive delivery rate as a function of operating conditions in the engine. This data shows that the system is generally beneficial and effective in actual field performance as well as in stationary engine test sequences.
