Energy-efficient renovation of existing residential buildings is an important energy policy in China, but financing difficulties seriously hinder the promotion of the policy. In this article, novel indices based on benefit-cost analysis are presented to overcome the barriers. Firstly,...

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...

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-...
