Abstract
The objective of this project is to determine the physical and chemical characteristics of particulate matter from internal combustion engines as a function of sampling procedure, engine operating conditions including emission control systems, fuel composition and residence time in the atmosphere. Work has proceeded using two matched automobiles to generate particulates. The automobiles are unusual in that they are equipped with measured and matched 1971 351 CID engines, one is being run only on unleaded gasoline and the other only on leaded gasoline, and both have been broken in using identical driving cycles. The total particulate emission rate from the nonleaded car is in the range 0.04-0.075 gram per mile for the 1972 FTP (Federal Test Procedures) Cycle. There is a correlation between the particulate and the hydrocarbon emission rates.
