Experimental Analysis of the Influence of Gear Shift Indicator on Vehicle Fuel Consumption

In order to analyze the influence of gear shift indicator on fuel consumption, a set of tests on the effect of gear shift indicator on fuel economy was designed based on EU regulation, and the specific test and analysis were carried out. According to the test method of EU regulations, the vehicle speed of gear shift points are collected, the engine speed and vehicle speed are read through the OBD-II data acquisition module, and the fuel consumption data is recorded by the fuel consumption meter. The fuel consumption of GSI recommendation and normal conditions are calculated. The fuel saving rate is 1.63% when used GSI recommendation shifting gear point. The results indicates that GSI has favorable fuel saving effect for normal vehicles.
