Reducing the pollution of internal combustion engines is a very important problem that can be solved in various ways. However, acoustic agglomeration method not used diesel engines. The study 1.9 TDI engine supplied with mixture (D100) and 90% rapeseed methyl ester - 10% propanol fuel (ROMEP). also changed position exhaust gas recirculation (EGR) valve by adjusting 20% EGR throughput limits mai...

To control the exhaust gas recirculation (EGR) and the exhaust brake, the position of a butterfly valve connected to a piston inside a pneumatic cylinder is controlled by altering the pressure inside the cylinder. This thesis evaluates the possibility to do this with pulse width modulation (PWM) controlled On/Off valves. The whole electro-pneumatic actuator system is built out of two On/Off val...

Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. Control structures are proposed and investigated for coordinated control of EGR valve and VGT position in heavy duty diesel e...

Minimizing fuel consumption of passenger car vehicles can be achieved thanks to hybridization the powertrain associated with innovative engine technologies. To feed new high compression ratio combustion systems, air system cutting-edge technologies are used manage and EGR (Exhaust Gas Recirculation) quantities. Increasing allows us improve in efficiency area, but it comes at cost a loss stabili...

Vehicle types, technologies, and driving conditions are key factors affecting emission fuel consumption. In this study, we measured the hydrocarbon (HC), carbon monoxide (CO), nitrogen oxide (NOx) factors, consumption of vehicles with a (1) carburetor (CVs), (2) multipoint injection technology three-way catalyst (MTVs), (3) technology, catalyst, exhaust gas recirculation device (MTEVs) under re...

Considering the concerns for emissions reduction in maritime sector, present paper evaluates, through modeling and simulation, oxy-fuel combustion a two-stroke ship engine (2SE) best production system configuration to obtain required oxygen (O2). An initial model of is calibrated with manufacturer’s data then adapted work O2 as oxidant eliminate nitrogen oxide (NOx) exhaust gas recirculation (E...

Albeit the exhaust gas recirculation (EGR) is widely used to reduce nitrogen oxides (NOx) emissions from large marine two-stroke engines, several challenges emerge for engine–turbocharging system matching considering contradictory requirements of engine and its subsystems operation. Such become more pronounced in complex configurations that include parallel turbochargers EGR along with cut out ...

The aim of this work is to investigate the effect exhaust gas recirculation (EGR: water vapor and CO2), with without O2 enrichment, on non-premixed turbulent flames stabilized a swirl burner. motivation includes CO2 capture applications using CO2, combustion biogas that containing use EGR or H2O in certain industrial reduce pollutant emissions. Experiments were carried out coaxial burner placed...
