Abstract
An internal combustion heat engine and cycle therefor comprising a two stroke cylinder and piston unit having a combustion chamber at the top of the cylinder, having a compression chamber at the bottom of the cylinder, and having a transfer chamber charged with compressed combustion support air transferred into the combustion chamber during initial movement of the piston in a first power stroke, followed by spark ignition and combustion to effect said power stroke with simultaneous compression in said compression chamber and with admission of compressed combustion support air into said transfer chamber during terminal movement of said power stroke, the compressed combustion support air being stored in the transfer chamber during a second exhaust stroke with simultaneous induction of air into the compression chamber.
Claims7
A two stroke internal combustion heat engine having a combustion chamber, a compression chamber, and a separate transfer chamber for storage of compressed combustion support air, and including:
- a cylinder with a head closing a top end thereof and the combustion chamber, and with a case closing a bottom end thereof and the compression chamber,
- a piston reciprocable in the cylinder and coupled to a crank by a connecting rod and together operable between a Top Dead Center position and a Bottom Dead Center position,
- intake valve means opening into the compression chamber continuously during a stroke of the piston from Bottom Dead Center position to Top Dead Center position to fill the same with combustion support air,
- storage valve means opening from the compression chamber and into the separate transfer chamber during at least a portion of a first power stroke of the piston toward Bottom Dead Center position to charge said separate transfer chamber with compressed combustion support air and storing said charge within said transfer chamber,
- transfer valve means opening from the separate transfer chamber and into the combustion chamber during the initial portion of the first power stroke of the piston from Top Dead Center position to fill the increasing volume of the combustion chamber with compressed combustion support air,
- fuel injection means admixing fuel into the compressed combustion support air in the combustion chamber,
- ignition means discharging a spark in the combustion chamber following the said initial portion of and to effect the first power stroke continuing to Bottom Dead Center position,
- and an exhaust valve means in the head of the cylinder and opening from the combustion chamber during a second reciprocal exhaust stroke from Bottom Dead Center position to Top Dead Center position.
