Abstract
The utility model relates to a diesel engine cylinder block structure which comprises a cylinder block. The top end of the cylinder block is provided with an upper counter bored hole and a lower counter bored hole, a lubricating oil duct is arranged between the upper counter bored hole and the lower counter bored hole, the bottom end of the cylinder block is provided with a main oil duct and an auxiliary oil duct which are connected through a connecting bridge, crankcases are arranged at two adjacent ends of the main oil duct and the auxiliary oil duct respectively, and crankcase vent holes are formed in the peripheries of the crankcases. The diesel engine cylinder block is simple in structure, reasonable in design and convenient to use, the main oil duct and the auxiliary oil duct can be communicated, the oil ducts are not easily blocked, oil leakage of the cylinder block in operation can be effectively prevented, oil consumption is reduced, and the power of the cylinder block is improved.
Description
Technical field
The utility model relates to a kind of cylinder of diesel engine body structure, belongs to diesel engine part technical field.
Background technique
As everyone knows; existing cylinder of diesel engine body technique is generally continued to use Britain's engine technology use eighties in last century on engineering motor more; although As time goes on carried out improvement repeatedly; but still exist many deficiencies, wherein, when carrying out work, diesel engine cylinder block often there will be stopping up of oil channel; in the time of stopping up of oil channel, there will be again the phenomenon of leakage of oil; cause a large amount of oil consumption, reduced the power of cylinder body simultaneously, therefore can not meet the client's needs that day by day change.
Model utility content
The purpose of this utility model is: for defect and the deficiency of prior art, provide a kind of simple in structure, a kind of cylinder of diesel engine body structure reasonable in design, easy to use, not only can connect the obstruction that major-minor oil duct is difficult for causing oil duct, and can effectively prevent that cylinder body is in the phenomenon of when work leakage of oil, reduce oil consumption, improved the power of cylinder body.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cylinder of diesel engine body structure described in the utility model, comprise cylinder body, the top of cylinder body is provided with counterbore and lower counterbore, between upper counterbore and lower counterbore, be provided with oil leab, the bottom of cylinder body is provided with main oil gallery and secondary oil duct, between main oil gallery and secondary oil duct, by connecting bridge, connected, wherein the two ends adjacent with major and minor oil duct are respectively equipped with crankcase, and the surrounding of crankcase is provided with crank case vent hole.
In the utility model: be provided with cylinder-bore and positioning pin hole on described cylinder body, be provided with stiffening rib between cylinder-bore and positioning pin hole.
Adopt after said structure, the utility model beneficial effect is: the utility model is simple in structure, reasonable in design, easy to use, not only can connect the obstruction that major-minor oil duct is difficult for causing oil duct, and can effectively prevent that cylinder body is in the phenomenon of when work leakage of oil, reduce oil consumption, improved the power of cylinder body.
