| 520 | 3 | |a Benefits that could be attained from a gasoline blended to provide improved short-trip fuel economy are assessed, approached with two goals in mind: (1) develop a test procedure to effectively evaluate any method that shows promise for improved fuel utilization; (2) use the procedure to obtain a better understanding of what is needed in present-day gasoline to improve short-trip economy. The short-trip cycle is a 3-stage test starting with the vehicle at ambient conditions and repeating a 0.685-mile-cycle ten times as the vehicle warms up. The vehicle is stopped for ten minutes. This is followed by the first 505 seconds of the EPA driving schedule commonly referred to as the hot transient run, or the 1975 Hot Run. At this time, the vehicle is considered to be fully warmed up, and the initial cycle is repeated three times. The factorial test design was used to compare typical seasonal fuels with a special fuel developed to better establish the effect of fuel gravity on fuel economy. Two operating temperatures, 0 and 90/sup 0/F, were used. The fuel effect was evaluated in small cars and in large cars and with standard carburetion and fuel injection. The four cars used in the program were a Cadillac Seville with fuel injection, an Oldsmobile Delta 88 with carburetion, a Volvo 245 DL with fuel injection, and a Ford Pinto with carburetion. The study estimates that an improvement of 1% in fuel economy during the first five miles will effectively reduce our annual gasoline consumption by 200 to 300 million gallons. (MCW) | |
