Immersion temperature effects on light-duty gasoline vehicles’ fuel consumption under world-wide harmonized light-duty test cycle (WLTC)

Basing on the experimental study of fuel consumbtion in World-wide Harmonized Light-duty Test Cycle (WLTC ), this paper conducted effects using different immersion temperature consumption a light-duty gasoline vehicle. The mainly studied first phase WLTC with three gaseous pollutant emissions: carbon dioxide, monoxide and unburned hydrocarbon(CO2, CO HC )which is measured to caculate Gasoline Vehicles. It appears that increase time working condition vehicle tends be stable resulting similar emission test. Which means emissions low-speed WLTC. Besides, cold start engine had generated large quantity hydrocarbon, but it for dioxide which was continuously whole phase. also found use higher temperatures (26℃) more favorable than lower (23℃) typy testing vehicle’s test cycle.
