Abstract

1508175 Air-cooled IC engines KLOCKNERHUMBOLDT-DEUTZ AG 27 March 1975 [1 April 1974] 12880/75 Heading F1B A finned cylinder 2 projecting into the crackcase 1, with the upper surface of the crank-case above the level of the top piston ring 6 when the piston is at bottom dead centre, has a portion within the crank-case surrounded by a part 5 of good thermal conductivity or by a space (12), Fig. 2 (not shown), for liquid coolant, e.g. engine lubricating oil. The part 5 may be shrunk on to the cylinder 2 or formed by compound casting and may be an aluminium casting also having the cooling fins and cast on a centrifugally cast liner (17), Fig. 3 (not shown). The coolant space (12), Fig. 2, receives oil from a crank-case duct (14) through a throttle (16) and discharges to the crank-case interior.
