An investigation on the effects of late intake valve closing and exhaust gas recirculation in a single-cylinder research diesel engine in the low-load condition

摘要: The effects of late intake valve closing and exhaust gas recirculation on the emissions engine performance a single-cylinder diesel research were observed. Two cam profiles (symmetric asymmetric) implemented using an offset angle at various timings to characterize emissions. injection swept every condition evaluate optimal operating conditions. highest indicated mean effective pressure was observed once combustion phasing tuned optimum crank (in degrees) by varying timing. exhibited slight penalty when both used in comparison with base timing no recirculation. However, appropriate combination reducing nitrogen oxide owing t...
