Gasohol is one of renewable clean alternative energies, which is widely used around the world. In fact, the gasohol had been raised to use Gasohol in 9 provinces of China since 2001. However, it was merely promoted the closed use in Heilongjiang Province since November 1, 2004. Moreover, this issue aroused an extensive discussion and controversy. Especially in the cold winter, some users reflect that the use of gasohol can create some disturbing problems, i.e., environmental pollution is further accelerated, condensation dripping water detection problem from exhaust pipe is increased and the acceleration performance of vehicle is decreased. In order to deal with it, presently, some scholars have addressed condensation dripping water detection and fuel economy issues under low environmental temperature conditions. However, they pay little attention to acceleration performance test and experiment issues of gasohol vehicle under low environmental temperature conditions. Taking the Harbin city as a case study, this work designs acceleration performance experiments for gasohol and gasoline vehicles with the same working conditions. Moreover, based on experiments data, taking interval acceleration time and distance as evaluation parameters, this work evaluates and compares the acceleration performance of gasohol and gasoline vehicles. Under low environmental temperature conditions, the results denote that the gasohol vehicle has a better acceleration performance than gasoline vehicle in the low speed region. Otherwise, the gasohol vehicle has a worse acceleration performance than gasoline vehicle in the low speed region. This result can help decision makers to perform better judgments when using the gasohol vehicle.
