Experimental comparison of different injection timings in an HCCI engine fueled with n-heptane

International Journal of Automotive Science and Technology, 2017
One of the most effective methods to control the combustion phasing of a homogeneous charged compression ignition (HCCI) engine is injection timing. Injection timing affects the homogeneity of the mixture, start of combustion and heat release rate.

Numerical Investigation on Effects of Assigned EGR Stratification on a Heavy Duty Diesel Engine with Two-Stage Fuel Injection

Energies, 2018
External exhaust gas recirculation (EGR) stratification in diesel engines contributes to reduction of toxic emissions. Weak EGR stratification lies in that strong turbulence and mixing between EGR and intake air by current introduction strategies of EGR.
