Abstract	Approximately 30% of the automotive fuel consumed in the United States is spent in trips of eight km or less. Fuel consumption in a short trip, or in the first few km of every trip, is higher than the fully-warmed-up (FWU) fuel consumption rate at "normal" ambient temperatures. Fuel consumption rate of gasoline-fueled vehicles increases as ambient temperature decreases. Studies indicate that for an eight km trip from cold-start, at 21 C fuel consumption rate may increase 10 to 20% over the FWU fuel consumption rate. At lower temperatures (-17 to 4C) fuel consumption rate over an eight km trip could increase 30 to 40% over the FWU rate. A testing program was conducted in a climate-controlled chassis dynamometer facility.
