A CFD Modelling Approach for the Operation Analysis of an Exhaust Backpressure Valve Used in a Euro 6 Diesel Engine

Harvesting residual thermal energy from exhaust gases with thermoelectric generators is one of the paths that are currently being explored to achieve more sustainable and environmentally friendly means transport. In some cases, installed in a by-pass configuration regulate mass flow entering generator. Some manufacturers using throttle valves electromechanical actuators electronic control pipe improve techniques for active pollutant emissions reciprocating internal combustion engines, such as gas recirculation. The above-mentioned circumstances have motivated approach this work: computational fluid dynamics (CFD) modelling operation valve used establishing adequate backpressure conditions low pressure recirculation Euro 6 engines. aim model understand process these types order incorporate them an system will include two convert into electrical energy. This work presents through under different temperatures rates closing positions. For all values drop were obtained. cases studied, level agreement between modelled experimental results exceeds 90%. developed has helped propose correlation estimate rate easily measurable quantities.
