Abstract
The utility model relates to a four-cylinder dry-type diesel engine body. Four cylinder sleeve mounting holes are formed in the top surface of the body, the center distance between every two adjacent cylinder sleeve mounting holes ranges from 110 mm to 115 mm, the inner diameter of each cylinder hole ranges from phi98 mm to phi102 mm, and the transverse center distance between each of four cylinder cover bolt connecting holes of each cylinder and each cylinder sleeve mounting hole ranges from 55 mm to 57.5 mm; the longitudinal center distance between each cylinder cover bolt connecting hole and each cylinder sleeve mounting hole ranges from 51.5 mm to 54 mm; the center distance between the top end of each of upper and lower breathing channels and each cylinder ranges from 80 mm to 83 mm; the diameter of an upper spigot ranges from phi103.5 mm to 107 mm; the distance between the end surface of the upper spigot of each cylinder hole and the top surface of the body ranges from 4.5 mm to 7 mm, and cooling water flows through an engine oil cooler cavity formed in the body to enter the body from a third cylinder. The body can meet the requirement of the maximum working explosion pressure in the cylinders for the strength and the rigidity of the body; the cooling water flow field is evenly distributed, so that the cooling effect on the body is guaranteed.
Description
technical field:
The utility model belongs to field of internal combustion engine, relates to a kind of diesel-engine body, relates in particular to a kind of dry type four-cylinder diesel engine body.
background technique:
Along with the increasingly stringent of China's road Abgasgesetz, research and development meet state's IV emission standard and possess the road diesel engine product that is upgraded to state's V discharge capacity has been the task of top priority.According to the demand for development of draining technology, diesel engine strengthening degree improves constantly, requirement cylinder-firing pressure increases, body must have good strength and stiffness, and the structure of further appropriate design cooling jacket, make it to meet the cooling requirement of body, guarantee complete machine reliable operation, meets the needs of product high-performance low emission.Also require form structure compactness simultaneously, reduce as far as possible volume and own wt, make diesel engine there is better power character and Economy.
model utility content:
The purpose of this utility model is to provide a kind of dry type four-cylinder diesel engine body, to meet the requirement of the Novel diesel engine with high reliability, energy-conserving and environment-protective supporting as road vehicle.
The technical solution of the utility model is: a kind of four cylinder dry type diesel engine bodies, four cylinder liner mounting holes are set on body end face, adjacent two cylinder liner mounting hole centre distance are 110～115mm, each cylinder-bore internal diameter is φ 98～φ 102mm, and four cylinder head bolt attachment holes of every cylinder and each cylinder liner mounting hole transverse pitch are 55～57.5mm; Cylinder head bolt attachment hole and each cylinder liner mounting hole longitudinal pitch are 51.5～54mm; Upper and lower respiration channel top and cylinder pintch are 80～83mm; Upper seam diameter is Φ 103.5～107mm; In cylinder-bore, seam end face is 4.5～7mm to the distance of body end face, and the machine oil cooler chamber that cooling water flow is arranged on body enters body at the 3rd cylinder place.The respiration channel up and down of body air inlet side and exhaust side, ensured the oil return on cylinder cap smooth and easy and and crank case vent, in structure, also strengthened body rigidity.
The utility model can reach following good effect: boundary dimension compactness, ensure the discharge capacity of diesel engine, and power per liter greatly increases.By the optimization of structural design and the checking of analog computation, ensure that designed body can meet the requirement of the strength and stiffness of maximum functional pressure of explosion to body in cylinder; Cooling water flow is evenly distributed, and has ensured body cooling effect.
brief description of the drawings:
Fig. 1 is the utility model four cylinder dry type diesel engine body end face schematic diagram.
Fig. 2 is the A-A sectional view of Fig. 1.
embodiment:
As shown in Figure 1, adjacent two cylinder liner mounting hole centre distance A1 are 110～115mm, and each cylinder-bore internal diameter B is φ 98～φ 102mm, and four cylinder head bolt attachment holes of every cylinder and each cylinder liner mounting hole transverse pitch X1 are 55～57.5mm; Cylinder head bolt attachment hole and each cylinder liner mounting hole longitudinal pitch Y1 are 51.5～54mm; Upper and lower respiration channel top and cylinder pintch Y2 are 80～83mm; Upper seam diameter B1 is Φ 103.5～107mm; In cylinder-bore, seam end face to the distance C of body end face is 4.5～7mm.
The utility model is by optimization, the Finite Element Aided Design of structural design, Flow Field Calculation, and reasonable Arrangement water channel and cooling water enter the position of body, ensure cooling evenly reliable; By appropriate design respiration channel, reasonable Arrangement passage distributes, and has strengthened cylinder block strength and rigidity, and can effectively reduce the noise and vibration of whole diesel engine.
