The zirconia solid electrolyte SOFC (solid oxide fuel cell) has the characteristics of oxygen ion conduction function, high-temperature resistance, thermoelectric coupling effect, etc. A NOx sensor based on common and problems with in principle application. research objective this paper is to solve application smart sensors diesel vehicles or gasoline vehicles. Improvements performance can help...

Wall-flow filters are a standard component in exhaust gas aftertreatment and have become indispensable vehicles. Ash soot particles generated during engine combustion deposited diesel or gasoline particulate filters. During regeneration, the oxidized. The remaining ash can form different deposition patterns: homogenous layer plug-end filling. It has not yet been clarified whether filling is fir...

The lubricating oil consumption (LOC) in internal combustion engines contributes to emission and deteriorates the performance of aftertreatment. In this work, an optical engine with a 2D Laser-induced fluorescence (2D-LIF) system was used study operating conditions critical real driving emissions. Additionally, numerical models were analyze ring dynamics, flow gas flow. It found that intake pre...

The Selective catalytic reduction (SCR) technique is widely applied in exhaust gas after-treatment of diesel engines. Depending on operating conditions, injected urea-water solution (UWS) can form liquid films mixer blades and the pipe wall. Evaporation subsequent reactions wall film lead to deposits urea by-products, respectively. Especially that are not decomposed up high temperatures challen...

Selective Catalytic Reduction systems (SCR) are very efficient on reducing NOx. However, they only perform properly when exhaust gas temperature is higher than 180 °C. This means that for low engine regimes combined with cold temperatures, SCR remains inactive. study presents a new approach to minimize the amount of NOx emitted by diesel engines Heavy-Duty Vehicles during and gases conditions. ...

The aim to reduce well wheel CO2 emissions incentives the utilisation of alternative fuels (low zero carbon content and/or low tank emissions) as enhancement engine efficiency. In parallel, reduction tailpipe brings new challenges such decrease exhaust gas temperature. This trend penalises ability aftertreatment system eliminate pollutant emissions. addition, combustion and modes induce changes...

In this work, analytical solutions are provided to the nonlinear equations arising in thermal and flow-induced vibration in fluid-conveying structures using Galerkin-differential transformation method with cosine aftertreatment technique. From the analysis, it was established that increase of the length and aspect ratio of the fluid-conveying structures result in decrease the nonlinear vibratio...
