Abstract
An improved ignition-combustion system for internal combustion engines comprising a compact combustion chamber zone (,) in the engine cylinder head (,) mainly under the exhaust valve (,) and with large air-squish zones (,) formed at the edge of the combustion zone which produce colliding squish flows (,) with high turbulence (,) at the center of the combustion zone, with one or two spark plugs (,) located at the edge of the combustion zone within the high squish zones, resulting in a combined ignition and combustion system of colliding-flow-coupled-spark discharge (CFCSD), with the ignition employing high energy flow-resistant ignition sparks which move under the influence of the squish flow towards the central turbulence region as the piston nears engine top center, to produce rapid and complete burning of lean and high EGR mixtures for best engine efficiency and lowest emissions.
