This report details the findings from a 27-month investigation under NAFEC Contract DOT FA74NA-1091 Phase I, to investigate the exhaust mission levels of five aircraft piston engines with respect to the 1980 EPA Emissions Standards. The work includes the development of procedures for the testing, measurement and calculation of emissions from these engines as well as the determination of emissions reduction potential from lean fuel-air ratio operation and spark timing variations. Practical limitations to lean operation are investigated and confirmation of these limits were sought through a flight test program on one of the engines. (Author)
