Abstract

Abstract:

As a result of global warming， attention has been paid to greenhouse gas emitted by vehicles. In order to quantify the effect of temperature on vehicle CO₂ emission， WLTC test cycle of a light-duty E10 gasoline vehicle is carried out at the ambient temperatures of -10， 0， 23 and 40 ℃ in this study. It is found that the CO₂ emission factors of -10 and 0 ℃ at hot-start are 10.4% and 20.8% higher than those at 23 ℃， respectively. For cold-start engine， achieving full warm-up is longer than 300 s， which is required by China 6 standard. The relative deviation factor RF of the vehicle with full warm-up is close to 1， and 23 and 40 ℃ are close to 1 at $R F 4 ?$ and $? R F 3$ ， respectively， indicating that the higher the ambient temperature， the shorter the time required to achieve full warm-up. The absolute deviation factors $A F 1$ and $? A F 2$ at -10 ℃ are 1.98 and 3.63 times higher than those at 23 ℃， respectively， which quantifies the difference of CO₂ emission of cold-start vehicles in winter and summer. There is a strong correlation between cumulative CO₂ emission and idle CO₂ emission factors， which can be used to establish or modify microscopic CO₂ emission models， and it is suggested that the change of ambient temperature should be taken into account when evaluating vehicle CO₂ emission.

Key words: CO₂ emission, CO₂ modeling, ambient temperature, light-duty vehicle, E10 ethanol gasoline, WLTC cycle, idle condition
