    摘要: Es sind Vorrichtungen zur Herstellung eines Zylinderkurbelgehäuses (10) mit einer Gießform (12) mit mehreren Formteilen (14, 16), zumindest einem Wassermantelkern (22), weicher an beiden Längsseiten (24) eines oder mehrerer eine Zylinderreihe bildender Formteile (20) angeordnet ist und zumindest einem Stegkern (28), welcher zwischen den die einzelnen Zylinder (18) einer Zylinderreihe bildenden Formteilen (20) angeordnet ist, bekannt. Die bekannten stegkerne werden zumeist an den Wassermantelkernen befestigt, so dass sich bei der Herstellung zu große Toleranzen bezüglich der Lage zu den Zylindern ergeben.
    Es wird daher vorgeschlagen, dass der zumindest eine Stegkern (28) in die Gießform (12) eingelegt und zur Gießform (12) ausgerichtet ist.

    摘要: Described herein is a cylinder block (1) for an internal-combustion engine comprising:
    - a body (2) including a top face (3), two end faces (4, 6), two side faces (8, 10), and a bottom face (12), where the side faces (8, 10) develop substantially in a longitudinal direction of the cylinder block (1); and
    - a plurality of cylinders (C1, C2, C3, C4) traversing the cylinder block (12) from the top face (3) to the bottom face (12), where the cylinders (C1, C2, C3, C4) are set in the aforesaid longitudinal direction,
    wherein associated to each cylinder (C1, C2, C3, C4) are a first cavity (16; 28; 40; 52) and a second cavity (18; 30; 42; 54), which are adapted to contain a cooling liquid and extend around respective portions of the cylinder (C1, C2, C3, C4) with an arched geometry, said first and second cavities (16, 18; 28, 30; 40, 42; 52, 54) opening out at the top face (3) and being closed in the proximity of the bottom face (12);
    wherein the first and second cavities (16, 18; 28, 30; 40, 42; 52, 54) of each cylinder (C1, C2, C3, C4) are separate from one another;
    wherein the first cavity (16; 28; 40; 52) of each cylinder communicates hydraulically with the first cavity of at least one adjacent cylinder so as to define a first cooling jacket (64);
    wherein the second cavity (18; 30; 42; 54) of each cylinder communicates hydraulically with the second cavity of at least one adjacent cylinder so as to define a second cooling jacket (66); and
    wherein the first and second cooling jackets (64, 66) develop substantially in the longitudinal direction along two sides of the plurality of cylinders (C1, C2, C3, C4).
    The cylinder block is characterized in that the first cooling jacket (64) is in fluid communication with a first supply channel (68) having a first inlet port (72), and the second cooling jacket (66) is in fluid communication with a second supply channel (70) having a second inlet port (74). Each of the supply channels (68, 70) is in fluid communication with a supply source (S) from which the cooling liquid is delivered to the first supply channel (68) and to the second supply channel (70) through the first and second inlet ports (72, 74) with a direction of flow such that the cooling liquid goes from the first and second supply channels (68, 70) towards the first and second cooling jackets (64, 66), coming out through the top face (3).

    摘要: The invention relates to a device for guiding media in a cylinder block and crankcase of a reciprocating piston in-line combustion engine having a number of cylinders. To this end, the media guide comprises, among other things, at least one cross-channel that leads from one longitudinal side to the other longitudinal side of the cylinder block and crankcase. A structurally advantageous and simple design is provided by virtue of the fact that the cross-channel runs inside a free space, which is formed by recesses of two adjacent pistons in the lower area of the piston skirts and above the crankshaft bearing of the combustion engine.

    摘要: An integral cylinder block (20) is provided having features which enhance structural stiffness, thereby reducing noise emissions. The block (20) includes an upper portion (24) with cylinder bores (26) and a lower portion (22) forming at least a part of a crankcase (28). At the upper and lower portions of the block, the casing (40) has sculpted wall portions (42, 44) with a curved, undulated shape. At a side of the cylinder block (20), a closed oil cooler cavity (80) is formed. A wall (86) is provided to generally separate the oil cooler cavity (80) from the water jacket (34) defined within the block (20). An opening (88) is provided in the wall (86), which is distally located relative to a water pump outlet (90) that provides a flow of coolant into the cavity (80), thereby improving the flow direction of coolant across the oil cooler. Also, an opposite side of the cylinder block (20) includes a closed tappet cavity (60) to accommodate pushrods. The closed tappet cavity (60) is defined by a sculpted tappet cavity wall (62) that is integrally formed with the upper and lower portions (24, 22) of the block (20), improving block rigidity.
