摘要： An improved exhaust system for water craft engines is disclosed, which consists in the main an exhaust manifold connected to the cylinder exhaust port of the engine, an exhaust pipe joined at one end to the exhaust manifold and a diffuser connected at one end to the other end of the exhaust pipe and at the other end to the rest of the exhaust system including a muffler and steam separator. The exhaust pipe is divided into two axial parts, the first vertical, largely U-shaped pipe portion for direct connection to the exhaust pipe at downstream thereof and the second horizontal pipe portion for connection at one end thereof to the first pipe portion at downstream thereof and at the opposite end to the diffuser. The second pipe portion is disposed to extend adjacent to the exhaust manifold and made integral therewith in a rigid assembly, with the first pipe portion being releasably secured to the exhasut manifold and second portion through bolts for easy disassembly in servicing. Thus, since the exhaust pipe is integrally attached to the exhaust manifold through its divided first pipe portion, the entire exhaust system is held in relatively firmly fixed position in the engine compartment of rather limited space, so that operations to secure the various devices of the exhaust system there are greatly eased.

摘要： A compression release device for side-valve and overhead-valve internal combustion engines is disclosed, which takes advantages of the difference in thermal expansion of different materials to control the valve opening depending on the condition of ambient temperature. A first material of comparatively higher linear expansion coefficient is used for the cylinders and cylinder head, while a second material of comparatively lower expansion coefficient for the push rods and tappets for either or both of the intake and exhaust valves, with the valve or valves being set to take a valve lift enough to cause the valve, upon compression stroke, to remain properly slightly open at cold start to ease crankshaft rotation, while stay fully shut, as a result of the cylinders and cylinder head having undergone a greater degree of thermal expansion than the push rods and tappets, when the engine gets warmed up.

摘要： An overhead valve engine including a bore for receiving a push rod for actuating a suction valve and a bore for receiving a push rod for actuating a discharge valve. Blowby gas is introduced into one of the bores from a crank chamber and supplied to the other bore via a rocker arm chamber to lubricate the push rods with oil mist in the blowby gas. After lubricating the push rods, the blowby gas is released via the breather gas from the engine.

摘要： A method for manufacturing a multiple-wall synthetic-resin case having vertical multiple walls. The case is manufactured by integrating both upper and lower halves into one piece by jointing together; more specifically, each of the vertical walls is manufactured by jointing the upper wall formed in the upper half to the corresponding lower wall formed in the lower half. The jointing portions of the respective pairs of mating vertical walls are provided with different elevations so that they form their individual closed loops on the respective planes of elevations different from each other, conductive wire is inserted between the jointing surfaces of the upper and lower wall halves at each mating portion and apply high-frequency-heating to the conductive wire for welding the jointing surfaces.
