Problems solved by technology

However, the diesel engine body in the prior art lacks power (due to the unreasonable design of the cooling system, the body temperature is too high and the oil inlet rate is limited); in addition, the rigidity and strength of the diesel engine body are not enough, which easily leads to the deformation of the cylinder of the diesel engine, causing Problems such as exhaust at the lower part of the cylinder, cylinder scuffing, and coking of the piston ring cannot guarantee the reliable operation and service life of the diesel engine

Abstract

The invention discloses a 4A2 diesel engine body. The 4A2 diesel engine body comprises an engine main body. A cover plate is arranged at the top end of the engine main body, and a stiffening plate is arranged at the bottom end of the engine main body. The engine main body is provided with transverse reinforcing ribs and longitudinal reinforcing ribs, and the transverse reinforcing ribs and the longitudinal reinforcing ribs are perpendicularly arranged in a staggered mode. Engine oil channels are formed in the engine main body. Primary engine oil pump inlet holes and secondary engine oil pump inlet holes connected with an diesel engine oil pump are formed in the front end of the engine main body, and primary engine oil pump outlet holes and secondary engine oil pump outlet holes corresponding to the primary engine oil pump inlet holes and the secondary engine oil pump inlet holes are also formed in the front end of the engine main body. Four air cylinders and a cooling flow channel surrounding the air cylinder are arranged in the engine main body, and the cooling flow channel extends to the peripheries of the primary engine oil pump inlet holes and the peripheries of the secondary engine oil pump inlet holes. The engine main body is further provided with oil return connectors matched for use. By the adoption of the 4A2 diesel engine body, the cooling system structure of the diesel engine body is improved, the oil channel feeding speed is increased, reliable operation of a diesel engine is guaranteed, the service life of the diesel engine is prolonged, and the actual using requirements are met.

Description

technical field [0001] The invention relates to a 4A2 diesel engine body, belonging to the technical field of diesel engine bodies. Background technique [0002] The internal combustion engine is a complex energy conversion machine. With the continuous improvement of the level of science and technology, the structure and arrangement of various types of internal combustion engines are also different. Using diesel as fuel, when the air is compressed in the cylinder to generate high temperature, the injected diesel is natural, and the internal combustion engine that expands the gas to do work is called a diesel engine. The power coverage of diesel engines currently produced in my country is 2.2-47280KW, the cylinder diameter of diesel engines is 65-900mm, and the speed is 5.6-4400r / min. Features: easy to start, easy to operate and maintain, compact structure, small size, light weight, easy to transport and install, good economy, wide range of use, is an ideal power machine, wi...
