Blaser, R F

This patent describes an internal combustion engine including a variable volume combustion chamber into which is admitted a fuel air charge during at least part of an intake and compression event forming part of the operating cycle of the engine, such charge being compressed during at least part of the intake and compression event, reacted during a combustion/expansion event, and discharged during an exhaust event; a piston means movable within a cylinder to vary its volume between the piston means and the head of the cylinder; means for independently supplying air and fuel to the combustion chamber in timed relationship with the movement of the piston means, and inlet and exhaust valves for controlling admission of air and fuel into the combustion chamber through an intake port and discharging of combustion products from the combustion chamber through an exhaust product respectively. The improvement includes: means for supplying substantially fuel-free air alone to a combustion chamber, means for supplying fuel into the combustion chamber during a later part of each charge intake and compressing event, whereby the proportion of fuel to air of each charge varies from excess fuel near the intake port, an air reservoir chamber means, a passageway between the combustion chamber and reservoir chamber.
