14 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 The Ogunmuyiwa Engine Cycle 14
