Summary:

An engine test has been developed to assess the impact of volatile phosphorus from passenger car engine oils on catalytic converter efficiency. The ten-day, steady-state, catalyst aging test was established to promote the production and consumption of volatile phosphorus species contained in crankcase vapors that are evacuated and combusted via the PCV system. A system for sampling, analyzing and identifying crankcase vapors led to a greater understanding of the phosphorus-based poisoning mechanism. Catalytic converter conversion efficiency was assessed through an engine-based system that swept catalyst inlet temperature from low to high while using a constant flow of controlled exhaust gas. The test results indicate correct ranking of field-tested oils that have catalyst poisoning data
