Thermoelectric generator (TEG) is a promising energy conversion device for vehicle exhaust waste heat recovery. Although TEG is desired to work under composite modes and operating conditions, the influence of start-up mode on the performance of TEG was rarely paid attention to. In this study,...

Effects of lubricant oil additive on the characterization of particles from a four-cylinder turbocharged diesel engine were investigated. Neat diesel and blended fuel containing oil pour point depressant (PPD) additive were chosen as the test fuels. Effects of different fuels on size...

In this study, the effects of lubricating oil additive diesel fuel on the diesel engine emission particles characterizations, such as size distribution, morphology, nanostructure and composition was investigated on a light-duty diesel engine. Fast particle spectrum analysis was used for the...

A Multi-Approach Evaluation System (MA-ES) is established in this paper providing comprehensive evaluations on Organic Rankine Cycles (ORC) used for waste heat utilization. The MA-ES covers three main aspects of typical ORC performance: basic evaluations of energy distribution and system...

Currently, 2,5-dimethylfuran (DMF) has already been extensively studied as a novel potential gasoline substitute. With its improved reaction sequences, another main molecule transformed from fructose has also aroused worldwide interest, which is known as 2-methylfuran (MF). MF has similar energy...

A novel dual-loop organic Rankine cycle (DORC) is proposed in this study, which consists a high-temperature (HT) loop and a low-temperature (LT) loop to recover the waste heat of the exhaust, engine coolant and residual heat of the HT loop. Net output power, utilization rate of engine coolant,...

Study on recovering waste heat of engine exhaust gas using organic Rankine cycle (ORC) has continuously increased in recent years. However, it is difficult to find out appropriate working fluids to match with exhaust gas waste heat due to high temperature. In this work, several tentative...

A technical method of recovering exhaust heat in internal combustion engine (ICE) is the thermoelectric generator (TEG), which contributes to efficiency improvement. In this study, a two-stage thermoelectric model is built using the exhaust gas of ICE as heat source. After comparing the single-...

EGR technique, as one of effective measures to reduce NOX formation, was firstly adopted in diesel engines. But with the growing energy and environment problems, EGR has been commonly used also in gasoline engines together with other advanced techniques. Since there hasn’t been any...

During anaerobic fermentation of waste activated sludge (WAS), the production of short-chain fatty acids (SCFAs), especially propionic acid which is considered as the most preferred carbon source for enhanced biological phosphorus removal, can be improved by controlling the suitable mass ratio...
