Abstract |
In response to a meeting with representatives of Volkswagen on September 14, 1979, a correlation study was organized to characterize some of the factors causing hydrocarbon offsets during the 1980 diesel certification program. (Volkswagen read 40% lower hydrocarbon emissions than EPA). The hypothesis presented at this time by Volkswagen were: (1) offsets do not occur because of sample line variations from lab to lab and (2) offsets are caused by diesel fuel composition differences between EPA's fuel and Volkswagen-Wolfsburg's fuel. These two hypotheses were tested in two separate experiments at EPA as part of the correlation study. In November, Volkswagen brought two vehicles to the United States and requested EPA to do a series of six Hot LA-4s on each vehicle at the EPA facility. This report is the summary of the three different studies performed in cooperation with EPA plus the results of independent Volkswagen cooling fan experiments. These studies included similar vehicles and facilities, but addressed different correlation cause/effect relationships. |
