Reducing diesel engine emissions under cold start conditions has become much more valuable as environmental issues important. Regarding conditions, this review summarizes the emission mechanisms and specifically focuses on research progress of four reduction strategies: biodiesel utilization, intake heating, injection optimization, aftertreatment technologies. In general, adding Di-Ethyl-Ether ...

This paper reviews the recent advances in management of nitrogen oxide (NOx) emissions from internal combustion engine light-duty and heavy-duty vehicles, addressing both technical legal aspects. Particular focus is devoted to often-virtuous interaction between new legislation imposing more restrictions on permitted pollutant emission levels technologies developed order meet these restrictions....

In this study, the use of a thermoelectric aftertreatment heater (TATH) to reduce NOx emissions in low demanding regimes diesel-powered Heavy-Duty vehicles (HDV) has been analysed. This system is composed by an Exhaust Gas Heater (EGH) that heats up exhaust gases engine regimes, order shorten time urea injected. Besides, TATH fed Automotive Thermoelectric Generator (ATEG) converts waste heat fr...

The influence of multimodal incident sound fields on the acoustic behaviour large aftertreatment devices incorporating a monolith is modelled and analysed in detail. analytical mode matching method applied to compatibility conditions three-dimensional at device geometric discontinuities, leading computation complex wave amplitudes all subdomains involved corresponding transmission loss.
