Abstract (en)
[origin: EP0671552A1] The coolant flows through a closed circuit system to a cooler (19). The system comprises a top set of passages (9) in the block (2) at combustion-chamber level, and a separate bottom one (5) at the crankcase (4). The top set is open towards the cylinder head (3), and forms a single top system of passages (12) with the coolant chambers. The chambers are connected to the passages in the block via ports (11) in the head bottom plate. The top system can extend downwards towards the crank-case as far as the level of the piston rings when the pistons (8) are at tdc. The bottom set of passages can be level with the piston bdc position.
