In the present paper, the effect of the clean-and-cold EGR flow on the performance of a diesel engine running under conventional and Low-Temperature Combustion conditions is investigated by means of experimental tests on a single-cylinder research engine. The engine layout was "ad hoc" designed to isolate the effect of the clean-and-cold recirculated gas flow on the combustion quality. The results have shown that the thermodynamic temperature is the main factor affecting the engine performances, while the effect of a cleaner EGR flow, in terms of lower smoke and unburned compounds (HC and CO), is negligible.

Abstract
In the present paper, the effect of the clean-and-cold EGR flow on the performance of a diesel engine running under conventional and Low-Temperature Combustion conditions is investigated by means of experimental tests on a single-cylinder research engine. The engine layout was "ad hoc" designed to isolate the effect of the clean-and-cold recirculated gas flow on the combustion quality. The results have shown that the thermodynamic temperature is the main factor affecting the engine performances, while the effect of a cleaner EGR flow, in terms of lower smoke and unburned compounds (HC and CO), is negligible.File in questo prodotto:
