Abstract
An internal combustion gasoline engine has an air intake assembly which injects air through the cylinder head into the cylinder to generate swirl (horizontal vortex) flow (as opposed to tumble (vertical vortex) flow) for stratified charge combustion, and to generate tumble flow for homogeneous charge combustion. The piston includes a cavity combustion chamber at the top surface of the piston, the cavity combustion chamber having an increasing cross sectional area as the top of the piston is approached.
