Total Filtration ™: The Influence of Filter Selection on Engine Wear, Emissions, and Performance

A first order empirical model relating filter efficiency and internal combustion engine wear (focused on diesel engine wear) was assembled. The model combines the wear mechanisms from an engine's lube oil, fuel, and air induction systems, with ambient, application, and service conditions to predict specific results. This area of study is known as: Total Filtration™. The predictions possible to date using the Total Filtration™ model include: changes in lube oil and fuel consumption, changes in particulate matter (PM) emissions, a profile of PM emissions by source, normalized wear ratings, and engine life. Model case studies are reviewed and specific prediction examples are provided.
