Abstract

The invention discloses a cylinder body of a multi-cylinder diesel engine. The cylinder body is characterized in that vertical dividing walls extending from front to back are arranged between cylinder holes of the cylinder body and a left outer wall thereof as well as between the cylinder holes of the cylinder body and a right outer wall thereof, a space between the cylinder holes and each of the left dividing wall and the right dividing wall forms a water jacket, a horizontal partition is arranged in the middle of a waterway to form an upper waterway and a lower waterway, an upper waterway water outlet communicated with the upper waterway is formed in the back of the right outer wall, the right outer wall is provided with a lower waterway water inlet communicated with the lower waterway, a plurality of water jacket water inlets are formed in the lower portion of the right dividing wall, a water flowing passage is arranged between every two adjacent cylinder holes, and a plurality of water feeding holes communicated with a cylinder cover are formed in the top surface of the cylinder body. The cylinder body of the multi-cylinder diesel engine has the advantages that every cylinder hole corresponds to one water jacket water inlet, so that flow uniformity of cooling water of every cylinder is guaranteed, transverse flowing of the cooling water is strengthened and cooling effects of every cylinder are ensured.

Description

technical field [0001] The invention relates to the field of engines, in particular to a cylinder block of a multi-cylinder diesel engine. Background technique [0002] The cylinder block is the most critical part of the diesel engine, and it is the main body of the engine. It connects each cylinder and the crankcase as a whole, and is the supporting framework for installing the piston, crankshaft and other parts and accessories. [0003] The cylinder block of a traditional multi-cylinder diesel engine has the following characteristics: the cooling water jacket around the cylinder bore of the cylinder block has only one water inlet, and the water inlet is designed at the front or rear end of the cylinder block, and the overall flow direction of the cooling water in the water jacket is from the front If the water flows backward or from the back to the front, the flow direction of the water is relatively single, and the water jacket is prone to flow dead angles, and the local ...
