Vehicle emission control systems, fuel composition, and fuel-derived engine deposits have been studied as variables affecting the exhaust emissions of eleven species of polynuclear aromatics (PNA) and phenols. Both deposit-formation fuels and various emission-test fuels were used in measuring PNA emissions. One standard production model automobile without emission controls, two with engine-modification controls, and two automobiles with experimental advanced emission control systems have been used in the program. All emission measurements were made on the seven-mode cycle with 2:1 hot/cold weighting.
