The purpose of the study was to collect evaporative running emissions data from a cross section of in-use, light-duty passenger cars. Forty vehicles were procured and tested using the 'LA-4' cycle (the EPA Urban Dynamometer Driving Cycle (UDDS)) and the New York City Cycle (NYCC). The LA-4 cycle was run three times with a two minute idle period between the first two runs. The NYCC was run six times with a two minute idle between the first five runs of the cycle. Tests were performed at 95 and 105 degrees Farenheit, and using 7.5 and 9.0 Reid Vapor Pressure (RVP) fuel. The report describes two types of running losses - Type 1 where emissions are emitted at a constant, low level (typical of late model, properly operating vehicles), and Type II emissions, where there is a high rate of emissions (typical in uncontrolled vehicles).
