Gantry type diesel engine body

Abstract

The invention discloses a gantry type diesel engine body. The gantry type diesel engine body comprises a body mechanical structure portion, a lubricating oil pipeline portion, a cooling water pipeline portion, a plurality of bolt holes and accessory mounting faces, the cylinder diameter of the body is 101mm, and the cylinder distance is 116mm. A body front end face (1) is a transmission case joint face, a body rear end face (2) is an upper flywheel casing end face and is a power output end, a body lower end face is an oil pan joint face (3), a main bearing cover mounting face (4) and a suspended type bearing cover form a main bearing hole for supporting a crankshaft, a V-shaped upper end face is a cylinder head mounting face (5), an integrated cylinder sleeve (6) is adopted for the body, a reinforcing rib (7) is adopted in a critical area of the body, and a supercharger mounting face (8) and a high-pressure pump mounting face (9) are positioned in a V-shaped included angle. The gantry type diesel engine body is made of vermicular graphite iron materials, thick in casting wall, light in weight, compact in structure, high in stiffness and reliability, good in NVH (noise, vibration and harshness), and high in integration level of a cooling water passage and a lubricating oil passage.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and belongs to components of internal combustion engines, in particular to a gantry type diesel engine body. Background technique [0002] The body is the main frame of the diesel engine, the installation basis of other parts, and the most critical part of the diesel engine. Its structure and force are very complicated, and its mechanical properties have a great impact on the reliability and durability of the diesel engine. The rationality of the body design affects the reliability, NVH and power performance of the diesel engine. [0003] At present, the water and oil circuits of many diesel engines are not highly integrated, and external pipelines are required, which virtually increases the peripheral space of the diesel engine, affects the compactness of the diesel engine, increases the weight of the diesel engine, and increases the cost of the diesel engine. Relatively poor. Contents...
