Abstract
The utility model discloses a structure of cylinder block of diesel engine, it contains: cylinder block lower part, cylinder block upper portion and cylinder jacket. Cylinder block upper portion detachable sets up on the cylinder block lower part. The cylinder jacket sets up in cylinder block upper portion. Therefore, the utility model discloses a structure of cylinder block of diesel engine, it is divided into dismantled and assembled cylinder block upper portion and cylinder block lower part, can select different cylinder block upper portion and cylinder jacket for use according to the diesel engine discharge capacity of difference, has reduced the quantity of different parts, has reduced manufacturing cost.
Description
Technical field
The utility model relates to a kind of motor engine block, particularly a kind of cylinder structure for diesel engine of single cylinder test.
Background technique
At present, in the cutting edge technology of research diesel engine, such as during ultrahigh pressure diesel injection technology, usually in the enterprising line correlation test of single cylinder test diesel engine, to eliminate influencing each other between each cylinder of multi-cylinder diesel engine, and ensure the accuracy of research.
For prior art, when studying the diesel engine of different displacements, need the corresponding single cylinder engine manufacturing different displacements, manufacture different cylinder block, and manufacture cost is high.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Model utility content
The purpose of this utility model is to provide a kind of cylinder structure for diesel engine, it is divided into the gentle inferior part of the cylinder block in removable cylinder block top, different cylinder block top and cylinder liner can be selected according to different diesel engine discharge capacities, decrease the quantity of different part, reduce manufacture cost.
For achieving the above object, the utility model provides a kind of cylinder structure for diesel engine, and it comprises: cylinder block bottom, cylinder block top and cylinder liner.Cylinder block top is dismountable to be arranged on cylinder block bottom, and cylinder block top comprises locating stud, cylinder block bottom has the positioning pin hole with this detent fit, and locating stud inserts in this positioning pin hole and makes the dismountable connection of the gentle inferior part of the cylinder block in cylinder block top.Cylinder liner is arranged at cylinder block top.Cylinder block top also has positioning boss.
Compared with prior art, the utility model has following beneficial effect: cylinder structure for diesel engine of the present utility model, it is divided into the gentle inferior part of the cylinder block in removable cylinder block top, different cylinder block top and cylinder liner can be selected according to different diesel engine discharge capacities, decrease the quantity of different part, reduce manufacture cost.
Accompanying drawing explanation
Fig. 1 is the sectional view of the cylinder block according to a kind of cylinder structure for diesel engine of the present utility model.
Fig. 2 is the cylinder block superstructure partial sectional view according to a kind of cylinder structure for diesel engine of the present utility model.
Main Reference Numerals illustrates:
1-cylinder block bottom, 2-cylinder block top, 21-locating stud, 22-positioning pin hole, 23-positioning boss, 3-cylinder liner.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 2, according to a kind of cylinder structure for diesel engine of the utility model embodiment, it comprises: cylinder block bottom 1, cylinder block top 2 and cylinder liner 3.Cylinder block top 2 is dismountable to be arranged on cylinder block bottom 1, and cylinder block top 2 comprises locating stud 21, cylinder block bottom 1 has the positioning pin hole 22 coordinated with this locating stud 21, and locating stud 21 inserts in this positioning pin hole 22 and makes the dismountable connection of the gentle inferior part of the cylinder block in cylinder block top 21.Cylinder liner 3 is arranged at cylinder block top 2.Cylinder block top 2 also has positioning boss 23.Wherein, between cylinder block bottom 1 and cylinder block top 2, inserted in positioning pin hole 22 by positioning boss 23 and locating stud 21 and position connection, to ensure accurate positioning.Cylinder block top 2 and cylinder liner 3 can have different distortion, to adapt to different cylinder diameters, when needing the single cylinder diesel experiment carrying out different displacements, cylinder block bottom 1 remains unchanged, change corresponding cylinder block top 2 and cylinder liner 3, just can obtain the diesel engine of different displacements, decrease the quantity of different part, and reduce manufacture cost.
Whereby, cylinder structure for diesel engine of the present utility model, it is divided into the gentle inferior part of the cylinder block in removable cylinder block top, can select different cylinder block top and cylinder liner according to different diesel engine discharge capacities, decrease the quantity of different part, reduce manufacture cost.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
