Abstract
The utility model discloses a general petrol single cylinder body, including cylinder block, cylinder jacket, the cylinder jacket passes through sealing washer sealing connection in the cylinder block, and cylinder block bottom flange has adjusting shim. The inner diameter of the cylinder sleeve is the cylinder diameter of the single cylinder, and the cylinder sleeve with different inner diameters is replaced, so that the cylinder diameter of the single cylinder can be changed, and the range is 60-110 mm. The height of the cylinder body can be adjusted by adjusting the gasket, and the change of the compression volume of the combustion chamber is realized, so that the compression ratio is adjusted within the range of 8-16. A water jacket is arranged between the cylinder body and the cylinder sleeve, and a water inlet and a water outlet are respectively communicated between the water jacket and the cylinder body. The utility model discloses compact structure, arrange simple, easy dismounting, adapt to different models only need change a small amount of spare parts alright, greatly reduced development cost, shortened the development cycle.
Description
Technical Field
The utility model relates to an automobile engine, concretely relates to general petrol single cylinder engine cylinder body.
Background
In recent years, single cylinder testing has played an increasingly important role in engine development. The single cylinder engine refers to a single cylinder engine with the same parameters as a multi-cylinder engine except for different cylinder numbers. The method has the advantages of short design trial production period, low design trial production cost, convenient assembly and disassembly of parts, flexible and adjustable parts and the like. The single-cylinder engine test mainly undertakes the tasks of combustion system development, fuel injector model selection, key part verification and the like.
The configuration of a single-cylinder engine and the specific research content vary greatly when different models are developed. At present, a single-cylinder engine cylinder body is of an integral structure, and a trial-manufacture cylinder body needs to be redesigned aiming at different engine types, so that the development cost is high, and the development period is long. Can divide into base and cylinder body two parts with the cylinder body, wherein the base mainly plays the support bent axle effect, and the cylinder body plays fixed cylinder jacket effect, and to different models, the cylinder body can keep general.
Disclosure of Invention
An object of the utility model is to provide a general petrol single cylinder engine cylinder body satisfies the different jar footpath single cylinder engine demands in the certain limit to reduce development cost, shorten the development cycle.
The technical scheme of the utility model as follows:
the utility model provides a general petrol single cylinder body, includes cylinder block, cylinder jacket, and the cylinder jacket passes through sealing washer sealing connection in the cylinder block, and the flange of cylinder block bottom has the adjusting shim.
The cylinder body of the general gasoline single cylinder engine is characterized in that the inner diameter of the cylinder sleeve is the cylinder diameter of the single cylinder engine, the cylinder sleeves with different inner diameters are replaced, the cylinder diameter of the single cylinder engine can be changed, and the range is 60-110 mm.
According to the general gasoline single cylinder body, the height of the cylinder body can be adjusted by the adjusting gasket, and the change of the compression volume of the combustion chamber is realized, so that the compression ratio is adjusted within the range of 8-16.
The general gasoline single cylinder body is characterized in that a water jacket is arranged between the cylinder body and a cylinder sleeve, and the water jacket and the cylinder sleeve are respectively communicated with a water inlet and a water outlet.
The utility model provides a general petrol single cylinder engine cylinder body compact structure, arrange simple, easy dismounting, adapt to different models only need change a small amount of spare parts alright, greatly reduced development cost, shortened the development cycle.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the utility model provides a general petrol single cylinder engine cylinder body comprises cylinder block 2, cylinder jacket 1, adjusting shim 3 and sealing washer 4. The cylinder sleeve 1 is hermetically connected in the cylinder body 2 through a sealing ring 4, an adjusting gasket 3 is arranged below a flange at the bottom end of the cylinder body 2, a water jacket 5 is arranged between the cylinder body 2 and the cylinder sleeve 1, and a water inlet 6 and a water outlet 7 are respectively communicated between the water jacket 5 and the cylinder sleeve 1.
The cylinder block is designed according to the requirement of the maximum working capacity during the design, and the cylinder block 2 is kept unchanged in different single-cylinder engine schemes so as to achieve universality.
The inner diameter of the cylinder sleeve 1 is the cylinder diameter of the single cylinder engine, and the cylinder sleeves 1 with different inner diameters are replaced in different single cylinder engine schemes, so that the cylinder diameter of the single cylinder engine is variable, and the range is 60-110 mm.
The height of cylinder body can be adjusted to adjusting shim 3, under the unchangeable circumstances of internal motion mechanism, through the adjusting shim 3 of changing different thickness, can realize that combustion chamber compression volume changes to the adjustment compression ratio, the scope is 8 ~ 16.
A water jacket 5, a water inlet 6 and a water outlet 7 are arranged between the cylinder body 2 and the cylinder sleeve 1, cooling liquid flows in the water jacket to play a cooling role, and the sealing ring 4 can ensure that the cooling liquid in the water jacket does not leak.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
