Huge amount of low-grade heat energy is discharged to the environment by vehicular engines. Considering the large number of vehicles in the world, such waste energy makes great impacts to our environment globally. Organic Rankine Cycle (ORC), which uses an organic fluid with a low boiling point working medium, is considered as the most promising technology to recover energy from low-grade waste...

OBJECTIVES Diesel exhaust is a common air pollutant made up of several gases, hydrocarbons, and particles. An experimental study was carried out which was designed to evaluate if a particle trap on the tail pipe of an idling diesel engine would reduce effects on symptoms and lung function caused by the diesel exhaust, compared with exposure to unfiltered exhaust. METHODS Twelve healthy non-sm...

Exposure to vehicle exhaust can drive up to 70 % of excess lifetime cancer incidences due to air pollution in urban environments. Little is known about how exhaust-derived particles and organic pollutants, implicated in adverse health effects, are affected by freezing ambient temperatures and the presence of snow. Airborne particles and (semi)volatile organic constituents in dilute exhaust were...

In this work a mathematical model for the dynamic thermal and the macrokinetic conversion behavior of a commercial automotive three-way exhaust catalytic converter is developed and parameterized with independent measurements. In spite of its relative simplicity the developed model is comprehensive enough to cover the major phenomena relevant for catalyst conversion under light-off conditions an...

While EER (Exhaust Energy Recovery) has been widely pursued for improving the total efficiency and reducing CO2 emissions of internal combustion engines, the maximum regenerated power from the exhaust energy has been proposed and calculated in terms of endoreversible cycle. In this paper, based on the experimental data of an EER system installed on a light duty gasoline engine, the exhaust ener...

in this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of exhaust gas recirculation (egr) temperature on destruction of the fuel’s availability due to combustion processes in idi diesel engine cylinder. to serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

Abstract The paper presents a comparative analysis of experimental data on combustion liquid hydrocarbon fuels in the presence superheated steam two designs developed burners. By example diesel fuel burnt spray burner it is shown that lower values nitrogen oxide contents exhaust gases are achieved comparison with an evaporative burner. At that, content carbon monoxide some regimes for minimum t...
