Operating Characteristics of a Homogeneous Charge Compression Ignition Engine with Cam Profile Switching - Simulation Study

Influence of composite after-treatment catalyst on particle-bound polycyclic aromatic hydrocarbons–vapor-phase emitted from modern advanced GDI engines

“…The multi-cylinder engine used for this research is the Jaguar AJV6 direct injection research engine having swept volume of 3 L with the specification given in Table (1 (1) used in this work has been described in a previous publication [24][25][26][27]. A positive displacement supercharger is connected to the engine to be used when needed, but throughout this research natural aspiration was implemented.…”

Control of harmful hydrocarbon species in the exhaust of modern advanced GDI engines

“…The variable valve timing system of the engine made it possible to change the valve timing for the inlet and exhaust valves within a 60 crank angle (CA) degree range. More details regarding the engine can be found elsewhere in [29] and [30]. In HCCI mode the engine was operated with a wide open throttle significantly reducing pumping losses.…”

Modeling of Homogeneous Mixture Formation and Combustion in GDI Engine with Negative Valve Overlap

“…Among these, mixture homogeneity at the end of compression stroke plays a crucial role in implementing HCCI successfully [1]. Various modeling strategies have been used to study combustion in HCCI gasoline engines, which include zero-dimensional single zone [2,3], quasidimensional multizone [4], onedimensional cycle simulation coupled with chemical kinetics model [5][6][7], multidimensional multizone [8][9][10][11], and multi-dimensional with detailed chemistry [12][13][14][15][16]. Multidimensional modeling provides high levels of accuracy but at the cost of computational time.…”
