Flow and combustion in disc and pent-roof SI engines [PDF]

open access: yes, 2006
Reported in this thesis is a study of combustion in a disc-shaped combustion chamber spark ignition engine, and in-cylinder flow and combustion in an idealised pent-roof spark ignition engine. Both engines were skip fired, to remove residuals and ensure
