    摘要: An air filtration system for an internal combustion engine is provided wherein the air filter has an exit orifice for sealingly engaging the air intake duct of a carburetor via a friction-fit. The friction-fit provides an integrated seal between the orifice and duct such that additional sealing means are not required. The friction-fit can be provided by a plurality of ridges formed along the interior surface of the orifice or by decreasing the cross-sectional area of the orifice in the direction of the internal cavity formed by the filter walls. Decreasing the cross-sectional area of the orifice is accomplished by providing a plurality of stepped diameters of a bottom surface material or a surface that conically slopes inward towards the cavity. In addition, the air filter can be secured to a platform of an engine by a holding arm having a hook shaped distal end with a catch that can be disengaged by pulling at a grip, thus allowing easy access to the filter for inspection, cleaning, and replacement.

    摘要: A one-bolt connecting rod for an internal combustion engine, compressor or other machine; a structure for aligning the shank and cap parts of a two-piece connecting rod; an aluminum fastener for aluminum connecting rods; an extrusion process for making connecting rods; and connecting rod parts made by a fine blanking process. In the one-bolt connecting rod, the unbolted junction of the shank and cap is of the hook-on-lug type, and the bolt runs longitudinally through the junction. The alignment structure is on one side a V-junction with contact only between slanting walls and on the other side a junction of two single-plane walls. The aluminum fastener is a threaded aluminum stud.

    摘要: An internal combustion engine having a crankcase with at least one cylinder and a coolant passageway formed therein surrounding said cylinder. An engine air intake supplies combustion air to the cylinder, and a coolant pump pumps coolant through the coolant passageway for cooling the cylinder. A reservoir in fluid communication with the air intake collects coolant leaking from the coolant pump. Coolant in the reservoir is drawn into the air intake, and ingested by the cylinder.
