Numerical study of EGR effects on reducing the pressure rise rate of HCCI engine combustion

Gen CHEN, Norimasa IIDA, Zuohua HUANG,

Frontiers in Energy 2010, Volume 4, Issue 3, Pages 376-385 doi: 10.1007/s11708-010-0118-6

Abstract: The effects of the inert components of exhaust gas recirculation (EGR) gas on reducing the pressure riseResults show that with constant fuel amount and initial temperature and pressure, as EGR ratio increasesWith constant fuel amount, mixtures with different EGR ratios can obtain the same CA50 by adjusting theUnder the same CA50, as EGR ratio increases, the LTHR timing is advanced and the duration of thermalinfluence of EGR dilution on chemical reaction rate is offset by other factors.

Effects of EGR on combustion process of DI diesel engine during cold start

PENG Haiyong, CUI Yi, SHI Lei, DENG Kangyao

Frontiers in Energy 2008, Volume 2, Issue 2, Pages 202-210 doi: 10.1007/s11708-008-0038-x

Abstract: Experiments on the effects of external and internal exhaust gas recirculation (EGR) on combustion andCombustion was improved during the initial ignition cycles by introducing internal or external EGR.The addition of an appropriate amount of internal or external EGR can promote the combustion stabilityHowever, excessive amounts of external EGR could lead to extremely unstable combustion or even misfiringExternal EGR reduced NO emissions effectively while internal EGR led to an increase in NO emissions due

Frontiers in Energy 2013, Volume 7, Issue 2, Pages 237-244 doi: 10.1007/s11708-013-0251-0

Abstract: Aimed at the contradiction of NO and soot emission control with exhaust gas recirculation (EGR) of turbochargeddiesel engine under transient operations, on this simulation platform, a transient EGR valve controlstrategy was proposed, which adjusted the EGR valve in adjacent level based on the feedback of its openingOn the one hand, compared with the previous control strategy, which closed the EGR valve during the whole

Combustion analysis of a hydrogen-diesel fuel operated DI diesel engine with exhaust gas recirculation

M. LOGANATHAN, A. VELMURUGAN, TOM PAGE, E. JAMES GUNASEKARAN, P. TAMILARASAN

Frontiers in Energy 2017, Volume 11, Issue 4, Pages 568-574 doi: 10.1007/s11708-017-0461-y

Abstract: The HRR peak pressure decreased with the increase in EGR rate, while combustion duration increased withthe EGR rate.The cyclic pressure variation also increased with the increase in EGR rate.

Effect of exhaust gas recirculation and ethyl hexyl nitrate additive on biodiesel fuelled diesel engine for the reduction of NO

K. VENKATESWARLU, B. S. R MURTHY, V. V. SUBBARAO, K. Vijaya KUMAR

Frontiers in Energy 2012, Volume 6, Issue 3, Pages 304-310 doi: 10.1007/s11708-012-0195-9

Abstract: Exhaust gas recirculation (EGR) proved to be an effective way to reduce the NO emissions.Test results show that the brake thermal efficiency increases with the increase in the percentage of EGRspecific fuel consumption and exhaust gas temperatures, and that bio-diesel with cetane improver under 20% EGRreduces NO emissions by 33% when compared to baseline fuel without EGR.carbon monoxide (CO), hydro carbon (HC) and smoke emissions increase with an increase in percentage of EGR
