摘要： A multi-cylinder engine intake and exhaust system of the present invention comprises a plurality of independent exhaust passages (52) each connected to an exhaust port (18) in a respective one of a plurality of cylinders (12), a collecting pipe (56) connected to downstream ends of the plurality of independent exhaust passages (52), and a volume-enlarged portion (62b) provided downstream with respect to the collecting pipe (56). Each of at least a downstream portion of each of the plurality of independent exhaust passages (52) and at least an upstream portion of the collecting pipe (56) is formed such that a cross-sectional area thereof gradually decreases toward a downstream direction. The volume-enlarged portion (62b) is formed such that a cross-sectional area thereof is relatively increased so as to cause a positive pressure wave of exhaust gas reaching the volume-enlarged portion (62b) to be reflected and converted to a negative pressure wave. A length (L1) between an upstream end of the collecting pipe (56) and an upstream end of the volume-enlarged portion (62b) is set to a dimension which allows a negative pressure wave generated through a phenomenon that a positive pressure wave of exhaust gas discharged from a certain one of the plurality of cylinders (12) is reflected by the volume-enlarged portion (62b) at a predetermined engine speed equal to or less than the preset reference engine speed (N1), to reach the exhaust port (18) in a preceding one of the remaining cylinders (12), whose exhaust stroke immediately precedes that of the certain cylinder (12), during the overlap period (T_O/L) in the preceding cylinder (12). This makes it possible to increase engine power output with a simple configuration.

摘要： A method and apparatus for the decomposition of hydrogen peroxide, particularly for use as a hydrocarbon well bore and pipeline cleaning and maintenance aid. The apparatus includes a decomposition engine having an inlet manifold extending centrally within the housing and having means for passage of hydrogen peroxide through the manifold wall through a catalyst stack. The decomposition products produced are directed through an exit venturi. The decomposition products are passed through a piping system which allow the selective venting or introduction of the products into a facility to be cleared. Control means are coupled to the engine and valving to allow for the selective adjustment of temperature and or pressure of the decomposition products, as well as the introduction and diversion of the blend into the facility.

摘要： A forced exhaust system for increasing engine efficiency has an engine with at least one cylinder. The cylinder has a combustion chamber and a moveable piston. An intake port provides air/fuel/oil to the combustion chamber. An exhaust port is connected to the combustion chamber to remove exhaust gasses and uses an exhaust valve to control the exhaust timing. An exhaust device is connected to the exhaust port and lowers the pressure at the exhaust port which forcefully removes the products of combustion from the combustion chamber after ignition when the exhaust valve is open. By applying a vacuum to the exhaust port, the exhaust gases are removed quickly and utilizes more of the compression stroke than is possible in conventional engines. In this way, the user is able to control the intake and exhaust pressures independently in a two-stroke engine.
