| Abstract |
Exhaust emissions from seven motorcycles were measured using three separate procedures for each bike. The first procedure used for the motorcycle tests was the Federal '7-mode' direct sampling procedure (applicable to 1970 and 1971 model year light duty vehicles), modified where necessary. The motorcycles were also tested on the Federal 'LA-4' bag sampling procedure (applicable to 1972 and newer light duty vehicles), modified as necessary. The final procedure used was a series of steady-state conditions designed to cover the range of operating conditions experienced by each motorcycle. The exhaust products measured during the steady-state tests included: total hydrocarbons; light hydrocarbons; CO; CO2; NO; NOx; O2; total aliphatic aldehydes and formaldehyde; particulate; and exhaust smoke. The motorcycles were operated on a modified automotive chassis dynamometer, and the emissions results are used in conjunction with statistics on motorcycle population and usage to estimate national emissions impact. |
