Investigation on the Development of Fuel Consumption for China’s Gasoline Passenger Car in Recent Years

Abstract

As the application of several energy saving technologies and the continuous tightening fuel consumption standards, the fuel consumption of China’s gasoline passenger cars is decreasing continuously. In this paper, the development of the standards related to fuel consumption was reviewed firstly, and the development of the fuel consumption for China’s gasoline passenger cars has been investigated based on the declared fuel consumption data of over 4800 vehicle models produced or imported in recent 5 years (2014-2018). Results showed that the average fuel consumption in 2018 decreased 6.4% compared to 2014, about 1.6% per year. In additions, the development of gasoline passenger cars with turbocharge engines and auto transmissions had a more significant effect on the fuel consumption reduction, and the annual decreasing rate reached 2.4% per year and 3.6% per year, respectively.
