Abstract: The upper retainer for retaining an upper portion of a valve spring is shaped like a perforated spinning top and is axially dividable into two identical elements which are coaxially disposed about the upper portion of the valve stem when assuming its operative condition. The retainer has, when assuming the operative position, a configuration which comprises a collar portion which is sized to be coaxially disposed within an upper portion of the valve spring, an annular flange portion extending radially outward from the upper end of the collar portion and engaging with the upper end of the valve spring, and means for achieving a spline connection between the central portion of the retainer and the upper portion of the valve stem.

Abstract: A piston ring for an internal combustion engine having a piston and a cylinder of an elliptical or oblong circular cross-sectional shape is divided into two or more segments which are connected end to end in a ring. Each of the end-to-end joints between the neighboring segments is so designed as to provide an adequate surface pressure of the piston ring against the cylinder wall when installed in a cylinder. In one embodiment, the piston ring comprises two arc segments each of which has two inward projections projecting from both ends of the segment, respectively. In the installed state, the two inward projections of one arc segment abut against the inward projections of the other segment, respectively, in such a manner that an abutting pair of the inward projections at each joint produce a force which tends to increase a gap clearance between the ends of the segments. In another embodiment, the piston ring comprises two arc segments and two rectilinear segments disposed, in parallel with each other, between the two arc segments to form an oblong circular ring shape. In the installed state, both ends of each arc segment is compressed between the two rectilinear segments so that the two arc segments push the rectilinear segments outwardly so as to increase the distance between the rectilinear segments.

Abstract: The level of coolant in the coolant jacket of an "evaporation cooled" engine (wherein the coolant is boiled off in place of being forcefully circulated) is detected by a plurality of level sensors so that even though the attitude of the coolant level changes due to a change in orientation of the engine or the like, as long as one of the sensors is immersed in the coolant, the pump which recirculates condensed coolant from a radiator is not energized. An additional low level sensor is used to lower the level of the coolant to an predetermined low level to promote rapid engine warm-up during cold engine starts.

Abstract: A bearing beam structure is secured to a cylinder block of an internal combustion engine and includes a plurality of main bearing cap sections each of which associates with each bearing section of the cylinder block so as to rotatably support a crankshaft. At least a beam section is rigidly connected to the lower end portion of each bearing cap section to securely connect all the bearing cap sections with each other. Additionally, first and second side wall sections are rigidly connected to the opposite side portions of each bearing cap section to securely connect all the bearing cap sections with each other. Accordingly, the bearing beam structure is improved in rigidity to suppress various vibrations of the cylinder block, thereby effectively achieving total engine noise reduction.

Abstract: A cylinder block comprises an upper block deck disposed along whole the periphery of a cylinder-barrel section to securely connect the cylinder-barrel section with a water jacket outer wall section. The upper block deck is located below the top of the cylinder block and so positioned that its center lies at the level of an uppermost part of the skirt section of a piston which is at a range from TDC to 30 degrees relative to TDC. Additionally, upper and lower water jackets are formed at the upper and lower sides of the upper block deck, and communicate with each other through water holes formed through the upper block deck. By virtue of the thus located upper block deck, the wall of the cylinder-barrel section is effectively prevented from vibration due to piston slap, thereby greatly reducing piston slap noise emitted from the cylinder block.
