Abstract

1,067,069. Two stroke I. C. engines. R. L. J-B, SAN MORI. Sept. 15, 1964 [Oct. 15, 1963], No.37648/64. Heading F1B. [Also in Division F2] In an I. C. engine having groups of cylinders made up of two parallel cylinders 2, 3, Fig. 2 each containing two opposed pistons 5, diagonally Opposite pistons are interconnected by links, 7, rockers 8 and pitmans 9. Each pitman 9 has a big end 18 which surrounds the outer ring (19), Fig. 3 (not shown) of roller bearing 12 and is surrounded by ring 20 and retained by plates 13. Each pitman little end 26 is engaged on a roller bearing 29 surrounding a sleeve on rocker axis 30 which engages yoke 27 of rocker 8. The opposite end of rocker 8 is engaged, through a rollers 35, by link 7 which rolls on reinforcing plate 34 mounted in piston 5. The rocker axes (10), are rigid with rings 40 which have eccentric inner and outer bores to permit adjustment of the compression ratio. In each cylinder group all four shafts may be interconnected to provide manual or automatic adjustment, e.g. by variation in pressure, of the compression ratio. Each crankshaft section has a fluted boss (57) engaging a fluted socket (58) of an adjacent crank-shaft. In another embodiment, the roller bearing on crank-pin (11), Fig.4 (not shown) is surrounded by a whorl (23) which is separated from opposite faces of a box-like recess (22) in a pitman (21) by needle roller shoes (24), the stroke of which is limited by abutments (25). Mixture is inducted into the engine through passage 41 and on the inward piston stroke valve (47), Fig. 5 (not shown) is initially moved inwardly by fractional engagement with the tail (46) of piston 5. Gases are then drawn into the space between piston 5 and head (44). Valve (47) continues to move until its rim (48b) engages sleeve (41b). On the outward stroke of the piston valve (47) is moved to the closed position whilst the gases beneath the piston are transferred through ports 51 to scavenge the combustion space by a transverse flow to exhaust ports 52 leading to exhaust passages 42. Lubrication A centrifugal pump feeds oil through duct (17) to channel (15) and bearings 12 are fed centrifugally through channels (16).
