Title:
AN IMPROVED COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2009/127003
Kind Code:
A8
Abstract:
A combustion engine wherein said engine includes a cylinder chamber, a cylindrical piston adapted to move up and down within a defined passageway provided for by said cylinder chamber. The piston is characterised in having at one end of the piston a segment of the circumferential edge of the piston end at a raised elevation with respect to a diametrically opposed circumferential edge segment of said piston end, such that the end face of the piston is configured as an ellipse. The cylinder chamber passageway has an ellipse end configuration of comparable dimension and inclination to the ellipse piston end face, such that when the ellipse piston face is moved up the cylinder passageway during a compression stroke and at the moment of combustion ah ignited mix of air and fuel injected into the cylinder has a contactable surface area of the ellipse face of the piston to power a return of the piston to its lower position inside the cylinder chamber passageway after the combustion event.
