The Effect of “Clean and Cold” EGR on the Improvement of Low Temperature Combustion Performance in a Single Cylinder Research Diesel Engine 2008-01-0650
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.
