Significant Difference

Refuse truck accounted for 70% of the sanitation vehicle, which was the major heavy duty vehicle type in city. Therefore its fuel economy and emission characteristics were under higher requirements. This research did the emission test on the chassis dynamometer by using compressed truck, testing C-WTCV and CCBC circle emission, and fuel consumption respectively. The research showed the Km fuel consumption of CCBC circle was about 1.3 times of the C-WTVC from the analysis of fuel consumption and the emission of CO2.From the analysis of emission factor, the emission of NOX and CO of the CCBC circle was both higher than the C-WTVC, respectively 1.9 times and 1.4 times. However, the emission of HC was only 36% of the C-WTVC. C-WTVC was very similar to the motor of the CCBC circle in city, however the motorway cycle and emission both had significant difference from CCBC circle.

Thermoelectric technology applied in vehicle has become significantly essential due to the global energy crisis and the environmental protection issues. A novelty energy efficient technology called localized air-conditioning (LAC) powered by thermoelectric generator (TEG), i.e., TEG-powered LAC, is proposed in order to better utilize the generated power of TEG, only then will the fuel economy improvement be achieved. This system which has little impact on the original automotive electrical system is basically comprised of LAC, TEG, converter, and battery. The TEG can directly convert thermal energy to electrical energy to power the novelty energy-efficient air-conditioning system called LAC. The submodels of LAC and TEG are built and integrated into a heavy-duty vehicle to quantitatively assess its performance by simulation analysis. The results indicate that the novelty TEG-powered LAC system can work normally with high efficiency and improve the fuel economy by 3.7%. Therefore, this system resolves the problem of proper use of the TEG's power and provides a fully new perspective to substitute the mechanical loads to engine with electrical loads powered by TEG to improve the fuel economy with much more practicality and rationality.
