Abstract
An internal combustion engine has a fuel injector in a side wall of each cylinder to direct a fuel jet onto a flat or concave impingement surface of a shield projecting into the cylinder from the cylinder head, to atomize the fuel in the vicinity of the sparking plug electrodes with minimal wetting of the cylinder walls and of the plug electrodes. The piston head is formed with an asymmetrically located combustion chamber surrounded by extensive 'squish' areas arranged to promote the formation of a fuel vortex in which charge stratification occurs centrifugally.
