Abstract
Official abstract text for this publication.
Disclosed is a cooler arrangement for cooling a cylinder of a combustion engine. The cylinder has a cylinder head and a cylinder liner. The arrangement comprises a cooling circuit with a first flow passage which leads coolant through a lower part of the cylinder head, a second flow passage which leads coolant through an upper part of the cylinder head, and a third flow passage which leads coolant through an upper part of the cylinder liner. The cooling circuit is adapted to initially leading coolant through the first flow passage before it is led in parallel through the second flow passage and the third flow passage.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cooler arrangement for cooling at least one cylinder of a combustion engine, wherein said at least one cylinder has a cylinder head and a cylinder liner, wherein said cooler arrangement comprises a cooling circuit with a first flow passage which leads coolant through a lower part of the cylinder head, a second flow passage which leads coolant through an upper part of the cylinder head, and a third flow passage which leads coolant through an upper part of the cylinder liner, wherein the cooling circuit is configured to initially lead a coolant through the first flow passage before it divides the coolant into two streams for substantially simultaneous input at substantially the same temperature to both the second flow passage and the third flow passage, and wherein the second flow passage and the third flow passage are each dimensioned so that the third flow passage conducts a larger flow of coolant therethrough than a flow of coolant through the second flow passage. 2. A cooler arrangement according to claim 1 further comprising an outlet duct which is situated at a lower level than said second and third flow passages wherein the coolant leaving the second flow passage and the third flow passage is gathered in the outlet duct. 3. A cooler arrangement according to claim 1 , wherein the cooler arrangement comprises a fourth flow passage which leads a cooling medium through a lower part of the cylinder liner. 4. A cooler arrangement according to claim 3 , wherein the coolant leaving the first flow passage is divide into three streams for substantially simultaneous input to the second, third, and fourth flow passages respectively. 5. A cooler arrangement according to claim 3 , wherein the cooler arrangement comprises a separate cooling circuit which leads a cooling medium through the fourth flow passage. 6. A cooler arrangement according to claim 1 , wherein said first flow passage comprises cooling ducts which carry a parallel flow of coolant through the lower part of the cylinder head. 7. A cooler arrangement according to claim 1 , wherein said first flow passage comprises cooling ducts which provide a coolant flow close to one or more inlet ducts and exhaust ducts located in the cylinder head. 8. A cooler arrangement according to claim 1 , wherein said first flow passage comprises cooling ducts which provide a coolant flow close to an injector in the cylinder head. 9. A cooler arrangement according to claim 1 , wherein the first flow passage comprises at least one vertical duct which leads coolant in a vertical direction close to an injector in the cylinder head.
