Abstract
1,048,330. Rotary-piston internal combustion engines. YANMAR DIESEL ENGINE CO. Ltd. Sept. 30, 1964, No. 39816/64. Heading F1F. To provide better temperature distribution around the periphery of the centre housing portion of a rotary-piston I.C. engine having an inner wall of epitrochoidal bi-arcuate profile co-operable with the corners of a three sided eccentrically mounted piston, a cooling water inlet is provided in the high temperature region of the periphery and partition means adjacent the low temperature region to prevent overcooling. As shown in Fig. 2, a centre housing portion 1 including a gas-mixture suction port 7, an exhaust port 8 and an ignition plug 20 includes a cooling water inlet 3 in the high temperature region A of the inner wall adjacent the ignition plug location where the explosion takes place. In the low temperature region B of the upper wall, i.e. in the region of the suction chamber, a partition wall 5 is formed in the centre housing portion rather nearer to the inner wall so that the major portion of the cooling water passes outside the partition before leaving through the outlet port 6 and has little effect in cooling the inner wall. In another embodiment, Fig. 4 (not shown), the inlet 3 includes a partition to divert a small portion of the water towards the low temperature region. In this embodiment, ribs 10, 11 extending alternately from opposite ends of the housing in the hot temperature region provide a tortuous path for the water to improve cooling of that region. In a further embodiment, Fig. 7 (not shown), the cold temperature region is aircooled and a cooling water outlet surrounds the exhaust port, additional to the cooling water outlet 6. In a still further embodiment a separate chamber is formed adjacent the low temperature region through which cooling fluid, e.g., lubricating oil, which is somewhat warmer circulates. The inner wall of the centre housing alternatively in the low temperature region may have radial axially-extending rib to prevent the cooling water actually contacting the inner wall of the housing.
