Abstract
The invention relates to the technical field of cylinders, in particular to an expended and power increased cylinder of a diesel engine, which is provided with a cylinder sleeve and a cylinder body, wherein the outer cycle of the cylinder sleeve is provided with a supporting mesa; the inner cycle of the cylinder body is provided with a protrusion supporting the supporting mesa; a water sealing ring is arranged in the connected position of the cylinder sleeve and the cylinder body; the supporting mesa is arranged in the middle lower end of the cylinder sleeve; the protrusion corresponding to the supporting mesa is arranged in the middle lower part of the inner cycle of the cylinder body; the water sealing ring is fixed in the connected position of the cylinder sleeve and the upper end of the cylinder body; and a cylinder sleeve spacer is arranged between the supporting mesa and the supporting protrusion. The invention has the advantages that the cylinder is expanded so that the engine has higher power in the conditions with same volume and weight, which saves space and cost; and the invention enables cylinder cover bolts to be arranged compactly so that the design of lightweight and high compatibilization of the whole engine is realized.
Description
Technical field
The present invention relates to the cylinder field, especially a kind ofly expand cylinder and cylinder of diesel engine that power increases.
Background technique
Cylinder is the cylindrical metal parts that the guiding piston carries out straight reciprocating motion therein.Working medium is converted into mechanical energy by expanding with heat energy in cylinder of diesel engine; Gas receiving piston in compresser cylinder compresses and raising pressure.Cylinder can be converted to mechanical energy with compressed-air actuated pressure, and driving mechanism is done straight reciprocating motion, swings and rotatablely moved.
Cylinder has cylinder sleeve, cylinder body, and the internal diameter size of cylinder barrel has been represented the size of cylinder ouput force.The cylinder liner supporting surface of existing motor is at its head portion, and this supporting surface cylindrical just of restriction cylinder liner maximum diameter and the minimum range of cylinder block bolt, because the restriction of distance makes existing engine power performance be restricted, and can't realize little, the high-power big power demand of the required volume of people.
Summary of the invention
The technical problem to be solved in the present invention is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of cylinder of diesel engine that can improve engine power.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cylinder of diesel engine, have cylinder sleeve and cylinder body, the cylinder sleeve outer ring has supporting table, the cylinder body inner ring has the projection that supports supporting table, the joint is provided with the water shutoff circle between cylinder sleeve and the cylinder body, supporting table is arranged on the middle lower end of cylinder sleeve, is arranged on the middle and lower part of cylinder body inner ring with the corresponding projection of supporting table, and the water shutoff circle is fixed in the joint of cylinder sleeve and cylinder body upper end.
Further,, improve the sealability of cylinder, be provided with the cylinder sleeve packing ring between supporting table and the supporting convex in order to make support effects good.
The present invention is because the maximum diameter of cylinder sleeve is the minimum range decision of supporting table cylindrical and cylinder bolt, and minimum range is a fixed value, cancelled the seam of cylinder sleeve upper end, supporting table is moved to the middle lower end of cylinder sleeve, all the other upper half part of cylinder sleeve with remained unchanged substantially originally, make the maximum diameter of cylinder sleeve become big now, realized the expansion cylinder of cylinder.
The invention has the beneficial effects as follows, cylinder of diesel engine of the present invention, owing to realized the expansion cylinder, make motor under the prerequisite of same volume, same weight, can obtain bigger power, save the space, save cost, the present invention makes cylinder bolt arrange compactness, thereby realizes the high up-Grading Design of complete machine light weight chemical combination.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the original structural representation of the present invention;
Fig. 2 is a structural representation of the present invention.
Among the figure 1, cylinder sleeve, 11, supporting table, 2, cylinder body, 21, projection, 3, the cylinder sleeve packing ring, 4, the water shutoff circle.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1 is the contrast of original structural representation, Fig. 2 is the cylinder of preferred forms shown in the present, have cylinder sleeve 1 and cylinder body 2, cylinder sleeve 1 outer ring has supporting table 11, cylinder body 2 inner rings have the projection 21 that supports supporting table 11, the joint is provided with water shutoff circle 4 between cylinder sleeve 1 and the cylinder body 2, supporting table 11 is arranged on the middle lower end of cylinder sleeve 1, be arranged on the middle and lower part of cylinder body 2 inner rings with supporting table 11 corresponding protruding 21, water shutoff circle 4 is fixed in the joint of cylinder sleeve 1 and cylinder body 2 upper ends, is provided with cylinder sleeve packing ring 3 between supporting table 11 and the support protrusion 21.
The present invention is because cylinder sleeve 1 is from the upper end is packed cylinder body 2 downwards into, and the supporting table 11 of general cylinder sleeve 1 is at its head portion, and restriction cylinder liner 1 maximum diameter is the minimum range of supporting table 11 cylindricals and cylinder block 2 bolts, now supporting table 11 is moved to lower end the cylinder sleeve 1 from the top, make cylinder sleeve 1 upper half part with remained unchanged substantially originally, be immersed in the cooling water, only cancel the top seam, make the maximum diameter of cylinder sleeve 1 become big, realize expanding cylinder.
The present invention can be used on the types such as single cylinder, multi-cylinder, makes the type that can not expand the cylinder increase-volume expand cylinder 5mm～7mm, and power increases by 10%～15%, saves cost.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
