Oxygen-enriched combustion of diesel engine can reduce smoke emission and improve thermal efficiency, but also lead to the increase of NO emission. In this research, experiments were conducted on a turbo-charged direct injection diesel engine under the two conditions of 2000 rpm and 180 Nm...

In the paper, combustion and emissions of a multi-cylinder CI (compression-ignition) engine fueled with DMF–diesel, n-butanol–diesel and gasoline–diesel blends were experimentally investigated, and fuel characteristics of DMF, n-butanol and gasoline were compared. Diesel was used as the...

Models of two-stage serial and parallel thermoelectric generators have been established in this paper. Low-temperature thermoelectric material bismuth telluride and medium-temperature skutterudite are employed in the models and the exhaust gas of internal combustion engine is used as heat...

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...

This paper presents a simulation model based on an actual Organic Rankine Cycle (ORC) bottoming system of a diesel engine. The ORC system is built to recover waste heat both from engine exhaust gas and jacket water using R245fa as working fluid. Simulations and thermodynamic analyses are...

For high temperature ORC (Organic Rankine Cycle) used in engine waste heat recovery, it's very critical to select a high temperature working fluid. HCs (Hydrocarbons) usually have excellent cycle performance, but the flammability limits their practical application. Considering that some...

The paper analyzes the combined TEG-ORC (thermoelectric generator and organic rankine cycle) used in exhaust heat recovery of ICE (internal combustion engine) theoretically. A theoretical model is proposed to calculate the optimal parameters of the bottoming cycle based on thermodynamic theory...

An Organic Rankine Cycle (ORC) system used in the Internal Combustion Engine (ICE) exhaust heat recovery was proposed and techno-economically analyzed based on various working fluids. It is significant to recover ICE exhaust heat (about one third of energy generated from the fuel) by ORC system....

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...
