Abstract
The invention relates to a cylinder block of the closed-deck type, which can be produced by die-casting. The cylinder block includes a water jacket surrounding the cylinders adapted to be open to the side. The lateral opening can be closed by a cover, which is additionally shaped on its inside in such a way as to promote flow distribution or heat dissipation.
Claims15
A cylinder block of the closed-deck type containing a cast cylinder-block core with at least two cylinders and a water jacket, wherein adjacent cylinders share a common cylindrical wall portion, and wherein the cylinder-block core does not surround the water jacket on an outer side facing away from the cylinder, and wherein the water jacket extends along only an upper 20% to 50% of the height of the cylinder.
A cylinder block of the closed-deck type containing a cast cylinder-block core with at least two cylinders and a water jacket, wherein adjacent cylinders share a common cylindrical wall portion, and wherein the cylinder-block core does not surround the water jacket on an outer side facing away from the cylinder, and wherein the cylinder-block core is made of aluminum.
A method of producing a closed-deck type cylinder block having at least two cylinders wherein adjacent cylinders share a common cylindrical wall portion, the method comprising the steps of die-casting a cylinder-block core and a water jacket wherein the cylinder-block core does not surround the water jacket on an outer side facing away from the cylinder, and forming the water jacket by machining a cavity into a lateral portion of the outer side facing away from the cylinder.
A method of producing a closed-deck type cylinder block having at least two cylinders wherein adjacent cylinders share a common cylindrical wall portion, the method comprising the steps of die-casting a cylinder-block core and a water jacket wherein the cylinder-block core does not surround the water jacket on an outer side facing away from the cylinder, and wherein the water jacket extends along only an upper 20% to 50% of the height of the cylinder.
A closed-deck type cylinder block comprising:
- a die-cast cylinder-block core having at least two cylinders with adjacent cylinders sharing a common cylindrical wall portion;
- a lateral water jacket formed on an outer side of the cylinder-block core facing away from the cylinder such that the cylinder-block core does not enclose the water jacket on the outer side;
- and
- a cover connected to the cylinder-block core enclosing the water jacket on the outer side facing away from the cylinder, wherein the water jacket extends along only an upper 20% to 50% of the height of the cylinder.
