Abstract:
An internal combustion engine, having a cylinder with a translating piston therein, employs a holding tank connecting, via a valve, to the combustion chamber of the cylinder for receipt of a portion of the engine gasses expelled during a compression stroke for providing that the expansion ratio of an expansion stroke is greater than the compression ratio of the compression stroke. The holding tank is located within a head of the cylinder, and has a single port serving for both ingress and egress of gasses to the combustion chamber. The holding tank is provided with one or more additional passages for connection to one or more additional cylinders in the event that the holding tank is shared among two or more cylinders.
Abstract:
The invention relates to a valve mechanism comprising a variable cross-section of a valve opening. Said valve mechanism is arranged on a flow opening of an internal combustion engine and comprises a gas exchange valve which is actuated by the force of a valve spring and can be displaced back and forth in the axial direction inside a guiding element by means of a valve control unit. The position of the sealing slide can be continuously adjusted in the axial direction in relation to the gas exchange valve by means of an adjustment unit. According to the invention, a sealing slide (10) is arranged coaxially in relation to the gas exchange valve (12). Said slide is actuated by the force of a coupler spring (24), and can be displaced back and forth in the axial direction by means of a valve control unit.
Abstract:
An Elevated Expansion-Ratio Internal Combustion Engine has a substantially standard repeating four-stroke sequence for each of a plurality of cylinders. The head of each cylinder has an intake valve, a combustion-gas exhaust valve, and a vapor return valve. A return manifold for vapor connects from respective ones of the cylinders via a plurality of valve assemblies, each of which includes the return valve, into a passage ahead of a beginning portion of an intake manifold. Each valve assembly also has a discharge valve coupled to the return valve via a holding tank for cylinder vapor or gas. Valve stems of the discharge and return valves are coaxial in a single section valve housing or spaced-apart in a two-section valve housing. A quantity of the vapor is received into the holding tank during the compression stroke, and subsequently transferred via the discharge valve to the return manifold.

The invention relates to a valve mechanism with a variable valve opening cross-section. The valve mechanism is arranged on the outlet of the internal combustion engine and comprises a gas exchange valve is impinged upon by the force of a valve spring and which can be displaced backwards and forwards in an axial direction inside a guide by a valve control unit. According to the invention, a sealing slide valve (10) is arranged coaxially in relation to the gas exchange valve (12) and is impinged upon by the force of a coupling spring (24) and is displaced backwards and forwards in the axial direction thereof by the valve control unit. The position of the sealing slide valve (10) can be altered in relation to the gas exchange valve (12) in an axial direction by a control unit.
