    Abstract: The present invention is a system for the distribution of the induction and exhaust flows for four-stroke engines, in which the engine valve/valves (V) are used both for the induction and for the exhaust. The valves (V) remain open from the beginning of the exhaust until the end of the induction; a mechanical system constituted by deviating valves (P), check plates or other elements provides for connecting, alternately, the exhaust pipe (S) and the induction pipe (A) with the engine valves (V). This way it is possible to exploit a greater transfer section between the combustion chamber and the exhaust and induction pipes.

    Abstract: In an engine for a motorcycle, a main shaft is supported rotatably by first and second support walls of a lower case which constitutes a part of a crank case. The center distance between the crank shaft and the main shaft is to be shortened while attaining a reduction in the number of parts and the number of assembling steps. A first bearing hole is formed in a first support wall for fitting therein and holding a first bearing which is mounted on one end of the main shaft. A second bearing hole is formed in a second support wall which permits the main shaft to be inserted therein from an opposite end side of the main shaft until one end of the main shaft is fitted in the first bearing. A second bearing is fitted and held in the second bearing hole so as to be fitted on the main shaft from the opposite end side of the main shaft after fitting of one end of the main shaft into the first bearing.

    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.
