The Ogunmuyiwa Engine Cycle The patented Ogunmuyiwa Engine Cycle for engines with their cylinder axes arranged substantially tangentially to a circle centered on main shaft axis, enables combustion to be carried out during the compression stroke of the cycle without damaging the engine. In this revolutionary cycle, during the period of combustion of the working fluid on the compression stroke, the burnt gases are successively compressed, causing a temperature increase, which supports the subsequent combustion of the unburnt gases so as to improve the opportunities for achieving a more complete combustion. This provides a combustion cycle independent of the current inhibitive combustion timing constraints to deliver a more complete combustion, enabling higher power densities, higher thermal efficiencies and lower raw HC & CO emissions to be achieved. This will enable vehicle manufacturers to meet the EU 6b, EU 6c and 2020 CO2 emissions levels with significantly reduced after treatment requirements. 16.06.2015 The Ogunmuyiwa Engine Cycle 14

Summary The Ogunmuyiwa Planetary Gears Reciprocating Piston Engine (Ref. WIPO Publication: WO9502114, Claims: 5-7, 9, 11-21) is able to achieve significantly higher thermal efficiencies than those possible with current gasoline and diesel engines; The patented Ogunmuyiwa Engine Cycle takes advantage of the knock resistant geometry of this engine concept to provide a combustion cycle independent of the current inhibitive combustion timing constraints to deliver a more complete combustion, enabling higher power densities, higher thermal efficiencies and lower raw HC & CO emissions to be achieved; This will enable vehicle manufacturers to meet the EU 6b, EU 6c and 2020 CO2 emissions levels with significantly reduced after treatment requirements. 16.06.2015 The Ogunmuyiwa Engine Cycle 20
