Problems solved by technology
[0004] The manufacturing process of the above-mentioned cylinder block, the cast iron cylinder block is heavy, which does not meet the current demand for lightweight engines; aluminum alloy or magnesium-aluminum alloy castings cannot be installed with wet cylinder liners due to insufficient material strength, and can only adopt a linerless structure. On the engine with a small load; and the aluminum alloy inlaid casting cylinder block has the disadvantages of complicated process and high cost

The invention discloses a combined cylinder block. The combined cylinder block comprises a cylinder block body, a cylinder block top plate and a cylinder sleeve, wherein the cylinder block top plate is arranged on the top of the cylinder block body, and the cylinder sleeve is inserted into a cylinder hole of the cylinder block body; and the cylinder block body is provided with cylinder block body positioning pin holed, a water hole sealing ring groove, a cylinder block body water hole, a cylinder sleeve hole sealing ring groove, a cylinder sleeve upper mounting hole, a cylinder sleeve lower mounting hole, a cylinder block body oil hole, a cylinder cover bolt mounting hole, an oil hole sealing ring groove and a top plate bolt mounting hole, and the cylinder block top plate is provided with top plate positioning pin holes, a top plate bolt mounting counter bore, a top plate water hole, a cylinder sleeve positioning hole, a cylinder sleeve supporting face, a cylinder sleeve supporting counter bore, a cylinder cover bolt passing hole and a top plate oil hole. Therefore, the combined cylinder block is simple and reasonable in structure, light-weight design can be achieved, cost is low, and the casting complexity degree is reduced.
Description
technical field [0001] The invention relates to the technical field of piston internal combustion engines, in particular to a combined cylinder block. Background technique [0002] The cylinder block is the skeleton of the engine, and it is also a key component that provides the energy conversion place for the engine. The cylinder blocks are all provided with a cylinder and a crankcase, and the crankcase is provided with a crankshaft mounting seat. The piston makes a reciprocating linear motion in the cylinder, and the piston is connected with the crankshaft through the connecting rod. The reciprocating motion of the piston is converted into the rotary motion of the crankshaft through the crank throw of the crankshaft, thereby outputting torque. [0003] At present, most of the engine cylinder blocks are made of uniform materials. The cylinder blocks of medium and heavy duty engines are generally made of cast iron. They can be used without cylinder liners, dry type cylinder...
