Abstract (en)

[origin: EP1008733A2] A second return line (8b) roughly parallel to the first return line (8a) connects to the cooling space (12d) of the last cylinder and runs along the output shaft valve seals without entry or branching of the channel. The cylinder cooling spaces are formed in spectacles shape on the head ajdoining the cylinder and the two return lines (8a,8b) merge in the crankcase or oil sump. A central cooling channel runs between the cylinder head cooling spaces (12a-12d) and the return lines and in this variant follows a zee trajectory from one end of the engine to the other so as to enclose the inlet channels.
