    Abstract: PROBLEM TO BE SOLVED: To provide a 4-cycle engine capable of effectively lubricating mobile valve systems and crank systems, while continually and smoothly fluidizing mixed air, through the use of reciprocating movement of pistons, and of supplying the mixed air into a combustion chamber at a high suction efficiency.
    SOLUTION: The engine comprises a valve-driving unit 23 designed to drive suction/exhaust valves 19 and 60, and a mobile valve mechanism 30 equipped with a conveyance unit 29 for conveying rotational power of a crank axis 8 to the valve-driving unit 23. An air suction channel 3 designed to introduce the mixed air M containing a fuel and a lubricating oil is connected with a mobile valve chamber 18 accommodating the valve-driving unit 23 and being linked to an air suction port 40. A circular route accommodating a mobile valve channel 24 contains the conveyance unit 29 and connects the mobile channel chamber 18 and the crank chamber 7; and an auxiliary passage 41 links the crank chamber 7 and the mobile valve chamber 18. Further, the engine is equipped with check valves 38 and 42, designed to allow the passage of only the mixed air that flows in the forward direction following the above stated order, in the auxiliary passage 41, connected to the mobile valve chamber 18, to the mobile valve channel 24, to the crank chamber 7, and finally to the mobile valve chamber 18.

    Abstract: An internal combustion engine includes at least one piston that compresses air in the lower cylinder chamber as it transitions from top dead center to bottom dead center during the power stroke. The air in the lower cylinder chamber is compressed between the downward-moving cylinder and a structure that substantially seals the lower chamber from the crankcase chamber so that compression takes place in a chamber smaller than the crankcase chamber.

    Abstract: The invention is concerned with a method of deriving mechanical work from a combustion gas in internal combustion engines and reciprocating internal combustion engines for carrying out the method. The invention includes methods and apparatuses for managing combustion charge densities, temperatures, pressures and turbulence in order to produce a true mastery within the power cylinder in order to increase fuel economy, power, and torque while minimizing polluting emissions. In its preferred embodiments, the method includes the steps of (i) producing an air charge, (ii) controlling the temperature, density and pressure of the air charge, (iii) transferring the air charge to a power cylinder of the engine such that an air charge having a weight and density selected from a range of weight and density levels ranging from below atmospheric weight and density to heavier-than-atmospheric weight and density is introduced into the power cylinder, and (iv) then compressing the air charge at a lower-than-normal compression ratio, (v) causing a pre-determined quantity of charge-air and fuel to produce a combustible mixture, (vi) causing the mixture to be ignited within the power cylinder, and (vii) allowing the combustion gas to expand against a piston operable in the power cylinders with the expansion ratio of the power cylinders being substantially greater than the compression ratio of the power cylinders of the engine. In addition to other advantages, the invented, method is capable of producing mean effective cylinder pressures ranging from lower-than-normal to higher-than-normal. In the preferred embodiments, the mean effective cylinder pressure is selectively variable (and selectively varied) throughout the mentioned range during the operation of the engine. In an alternate embodiment related to constant speed-constant load operation, the mean effective cylinder pressure is selected from the range and the engine is configured, in accordance with the present invention, such that the mean effective cylinder pressure range is limited, being varied only in the amount required for producing the power, torque and speed of the duty cycle for which the engine is designed.

    Abstract: An intermittent bypass system comprises an intake conduit including an intake passage leading to a cylinder in an engine and an intake controller connected to the intake passage adjacent to the cylinder. The intake controller enables, during different portions of the engine cycle, fluid flow from the intake passage into the cylinder, fluid back-flow from the cylinder into the intake passage, and obstruction of fluid flow between the intake passage and the cylinder. A check valve is located in the intake passage upstream of the intake controller with the check valve allowing fluid flow toward the cylinder and obstructing fluid back-flow in the reverse direction. A bypass port is located on the intake passage to provide a flow path to a downstream portion defined by the portion of the intake passage between the check valve and intake controller. A control valve is connected between a secondary fluid source and the bypass port enabling communication between the secondary fluid source and downstream portion during a portion of the engine cycle when the check valve is open. The control valve obstructs the communication during a portion of the engine cycle when the check valve is closed.

    Abstract: The disclosed turbo-alternating engine exploits the gas generated in the cylinder of the alternating system in order to actuate a system of turbines ahead of the cylinders and at the extremity of the crankshaft in order to transmit the power thus generated to the crankshaft. Such reciprocal assistance of the turbo and alternating system makes possible the use of all the thermodynamic energy resulting from the combustion. As expressed before, the turbo-system does not consume fuel but it does take advantage to a maximum of the product of the combustion of the alternating system.
