The role of the China 240-1002001 cylinder block is : The main engine, it will all the cylinders and crankcase together, is the installation of Pistons, crankshaft and other parts and accessories supporting framework.

The MTZ Tractor Cylinder block 240-1002001 is the main component of an internal combustion engine with two or more cylinders. It's a one-piece piece piece that holds the engine cylinders together. Usually cast iron,-rarely cast iron.-aluminum. The cylinder body has a support surface for mounting the crankshaft. The cylinder head is usually attached to the top of the cylinder body and the lower part is part of the crankcase. Therefore, the cylinder block is the basic (main) part of the engine to which the rest of the parts are connected in one way or another. The cylinder in the cylinder block may itself be part of the cylinder block casting or may be a separate replaceable bushing ("bushing") , bushings can be "wet" or "Dry"-depending on whether they are cooled by direct contact with the coolant in the jacket. In addition to the functions of the body parts, the cylinder block has other functions: It is the main part of the lubrication system-the supply of pressurized oil to the lubrication point through the passage in the cylinder block, and in a liquid-cooled engine-and a cooling system: the coolant is formed through a cavity inside the cylinder block to circulate the cooling jacket. When the piston moves between the limit positions, the wall of the cylinder body cavity can also be used as a guide for the Piston. Thus, the length of the cylinder busbar is determined by the length of the piston stroke.

The wear of automobile engine cylinder is the result of the complex influence of various fast-flowing physical and chemical processes on the cylinder wall, there are three main types of wear: Abrasion (caused by mechanical wear, biting and other destructive processes that come into direct contact with the friction surface of the metal) ; corrosivity, caused by various oxidation processes on the friction surface; and Abrasives, will destroy the friction surface in the presence of solids or abrasive particles between them (including worn products) .
