Abstract

674,713. Combustion chambers. MAYBACH, K. Sept. 28, 1950 [June 7, 1950], No. 23769/50. Classes 7(ii) and 7(iii) A Deisel engine cylinder head is provided with a total number of inlet and exhaust valves exceeding four for each cylinder and a combustion chamber situated on or near the cylinder axis comprising over half the compression volume. As shown, each cylinder head comprises three inlet valves 5 and three exhaust valves 6, arranged in a circle around the combustion chamber 21 which comprises almost the whole compression volume. The combustion chamber, Fig 4, comprises an outer jacket 43, in contact with the cylinder head cooling-fluid and separated by an air space 53 from the inner wall 41. The jacket 43 and wall 41 each comprise two welded parts 43, 44 and 41, 42 which are centred during assembly by bosses 49, 50. The fuel nozzle mounting 46, integral with the jacket part 44, isin contact with the cooling fluid and is threaded at 47 for connection of the fuel pipe. A packing 3 is inserted between the cylinder liner 2 and the head, and rubber packing pieces 32, 35 are provided with apertures connecting the cylinder cooling jacket to the head. The part of the piston opposite the combustion chamber mouth may be provided with cooling oil passages.
