A numerical study on the effects of EGR and spark timing to combustion characteristics and NOx emission of a GDI engine
(Taylor and Francis Inc., 2016)
EGR is one of the most significant strategies for reducing especially nitrogen oxides (NOx) emissions from internal combustion engines. The thermal efficiency of spark ignition engines is lower than compression ignition ...
Mapping of an HCCI engine using negative valve overlap strategy
(Taylor and Francis Inc., 2020)
In order to control combustion phasing and extend operation range of homogeneous charged compression ignition (HCCI) engines, several techniques such as controlling inlet air temperature and pressure, using alternative ...
