    Abstract: PURPOSE:To enlarge the opening area of a valve led to a combustion chamber and consequently improve the suction and exhaust efficiencies by a structure wherein a single valve is provided in the combustion chamber both for suction and exhaustion and secondary valves are provided in passage led to said valve for separating suction air and exhaust gas from each other. CONSTITUTION:During operation, when a large diameter valve 1 is open with the downward motion of a piston 4, the pressure in a combustion chamber lowers itself and causes to open a secondary valve 2 for suction, resulting in sucking mixture 5 through a suction passage into the combustion chamber. After that, when the piston 4 past the bottom dead center starts to move upward, the large diameter valve 1 is closed and the mixture 5 is compressed. When the piston 4 reaches near the top dead center, the mixture 5 is ignited and exploses, resulting in causing the piston 4 to move downward. Finally, when the piston 4 passes the bottom dead center, the large diameter valve 1 is open, resulting in discharging the exhaust gas through an exhaust passage by pushing open a secondary valve 3 for exhaustion with the upward motion of the piston 4.

    Abstract: Diese Brennkraftmaschine umfaßt mindestens zwei Einlaßventile (9,10) und ein Auslaßventil (12) pro Zylinder, die mittels einer Einlaßnockenwelle (7) und einer Auslaßnockenwelle (8) betätigt werden und mit variablen Steuerzeiten arbeiten. Außerdem ist die Brennkraftmaschine mit einer Sauganlage versehen, die getrennte, zu den Einlaßventilen führende Saugkanäle (16,17) aufweist. Wenigstens in einem Saugkanal (16) ist eine Steuerklappe (18) vorgesehen.
    Damit die Brennkraftmaschine bezüglich Abgasemission, Kraftstoffverbrauch, Leistung und Drehmoment optimiert arbeitet, werden die Steuerzeiten der Ventile und die Durchströmung der Saugkanäle in Abhängigkeit von den definierteren Kennfeldbereichen eines Drehmoment-Drehzahl-Diagramms beeinflußt.

    Abstract: An improved internal combustion piston engine that utilizes, in combination at least one poppet valve 52 of known type and a sleeve valve 5 to affect the functions of intake and exhaust gas flow. The resulting gross increase in valve area and volumetric efficiency enables the engine to produce high specific power without large valve opening durations or valve overlap and the resultant undesirable increase in low speed pollution and torque reduction. One embodiment of this invention will use the at least one poppet valve 52 as an intake valve, and the sleeve valve 5 as an exhaust valve. Another embodiment of this invention will use the at least one poppet valve 52 as an exhaust valve, with the sleeve valve 5 performing the intake valve function. Additionally, the sleeve valve may be either constantly or intermittently or incrementally moved to open or close a port through described methods. Intermittent movement of the sleeve valve may be controlled by a computer 77 in known manner, a novel advantage being that a relatively small amount of energy is required for this function because the sleeve is largely moved by friction with the piston 46 or associated parts 47, 48, 49. Another novel feature is the use of engine oil instead of a water based coolant to control heat in the cylinder sleeve area 10. This minimizes friction and significantly simplifies cylinder block design and manufacture. The use of poppet valves which are either intake or exhaust valves simplifies cylinder head design, and the elimination of cold and hot valve and port areas in the confined space of a cylinder head reduces the complexity of design for use of ceramic materials.

    Abstract: An inlet manifold active reed valve for an internal combustion spark ignition engine comprises a solenoid activated reed just upstream of the inlet poppet valve of a four stroke engine. For a two stroke engine the active reed valve is located at the entrance to the crankcase and activated by one or more miniature solenoids attached to the valve body. As an alternative, the new valve is a rotary disc valve reciprocated by an external solenoid or a rotary activator. The valve opens fully for full unrestricted flow (unthrottled) during a portion of the time the inlet valve or part is open (in terms of crankshaft angle). The portion of crankshaft angle the new valve is fully open is determined by the engine load. Under full load the new valve may be held constantly open to provide unrestricted flow to the engine inlet valve or crankcase. In the above embodiments an electronic control unit energizes the solenoid or activator in response to engine operating conditions and pollution control regulations.
