Novy, V A

A gaseous fueled Otto cycle internal combustion engine is described, comprising: (1) at least one combustion chamber formed by a piston and a cylinder having intake and outlet valves; (2) intake manifold means for delivering a charge of fuel-air mixture through the intake valve to the combustion chamber; (3) mixing means connected to the intake manifold means and disposed upstream with respect to the intake valve for controlling the ratio of the fuel-air mixture; (4) spark ignition means for igniting the charge in the combustion chamber; (5) an inlet communicating with the intake manifold means and adjacent the upstream side of the intake valve, the air inlet being disposed to create when the intake valve is opened a gradient of fuel concentration within the combustion chamber consisting essentially of a layer of air adjacent the piston with the remaining portion of the combustion chamber towards the spark ignition means containing a gradually richer fuel concentration and (6) air control means adapted to permit the adjustment of the amount of air delivered through the air inlet.
