Abstract
The utility model relates to a single-cylinder air cooling cylinder liner diesel engine, which belongs to the technical field of power equipment; the diesel engine is mainly formed in the way that a camshaft, a crank shaft, a fuel injection pump and a balance shaft are installed on an engine body, one end of a connecting rod is connected with the crank shaft, and the other end of the connecting rod is connected with a piston, the piston is arranged in a cylinder sleeve, and a fuel injector is mounted on a cylinder cover; the diesel engine is characterized in that the cylinder sleeve and the engine body adopt two units respectively, and the engine body, the cylinder sleeve and the cylinder cover are connected into a whole through a cylinder cover bolt. The diesel engine has the advantages of compact and reasonable structure and convenient maintenance; moreover, the cylinder sleeve and the engine body are made from different metal materials, so that resonance caused in the operation process of the engine can be overcome, and the noise can be reduced; and compared with the engines with the same power, the mass power ratio of the engine is greatly improved than other engines with the same type, and the ratio of other engines is 13 kW/kg while that of the engine can achieve 0.18 kW/kg.
Description
Technical field
The utility model relates to a kind of single-cylinder wind cooling cylinder sleeve type diesel engine, and specifically KM12DL-500F single cylinder vertical type diesel engine belongs to field of power equipment technology.
Background technique
In existing technology, single-cylinder air-cooled diesel engine all adopts body and cylinder sleeve complete machine structure, makes in body the processing technology complexity, particularly engine operation process, and cylinder sleeve must be changed whole machine body, maintenance difficult and cost costliness after producing wearing and tearing.In addition,, be easy to generate resonance, engine noise is increased because outer radiating fin of cylinder sleeve and body are that commaterial is made.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of single-cylinder wind cooling cylinder sleeve type diesel engine, body and cylinder sleeve are made two complete unit, overcome the resonance in the engine operation process, engine noise is reduced greatly, thereby make this engine body processing technology simple, assemble easy to maintenancely, and greatly reduce maintenance expenses.
The technological scheme that provides according to the utility model, single-cylinder wind cooling cylinder sleeve type diesel engine comprises engine body, camshaft, bent axle, Injection Pump, connecting rod, cylinder liner, piston and cylinder head, described camshaft, bent axle, Injection Pump, trunnion shaft is installed on the engine body respectively, connecting rod one end is connected with bent axle, the other end of connecting rod is connected with piston, piston is contained in the cylinder liner, oil sprayer is contained in above the cylinder head, feature is: described cylinder liner and engine body are respectively two unit, by cylinder head bolt, engine body and cylinder liner and cylinder head are connected into integral body.
Compared with the prior art the utility model has the following advantages:
The utility model compact structure, reasonable, because cylinder liner and body are respectively two unit and assemble, so assembling, easy to maintenance, and because above-mentioned two parts are that different metal material is made, reduce noise so in engine operation process, can overcome resonance, in addition since structure rationally, make this machine and compare its mass-power ratio with power engine and improve greatly than other motors of the same type, other types are 0.13kw/kg, and this function reaches 0.18kw/kg.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise engine body 1, camshaft 2, bent axle 3, Injection Pump 4, connecting rod 5, cylinder liner 6, cylinder head bolt 7, piston 8, cylinder head 9, oil sprayer 10 and trunnion shaft 11 etc.
The utility model adopts camshaft 2, bent axle 3, Injection Pump 4, trunnion shaft 11 to be installed in respectively on the engine body 1, connecting rod 5 one ends are connected with bent axle 3, the other end of connecting rod 5 is connected with piston 8, piston 8 is contained in the cylinder liner 6, oil sprayer 10 is contained in above the cylinder head, described cylinder liner 6 is respectively two unit with engine body 1, by cylinder head bolt 7, engine body 1 and cylinder liner 6 and cylinder head 9 is connected into integral body.Described engine body adopts the alloy aluminum material to make.Described cylinder liner adopts alloy cast iron material to make.
Working principle of the present utility model and working procedure:
Principle of the present utility model mainly is that it produces the inconsistent principle of vibration frequency according to different materials, makes motor reduce noise, in addition cylinder sleeve is used instead the alloy cast iron integral casting process, can make its cooling effect better.This scheme can also make the motor complete machine structure become independently parts, and its difficulty of processing reduces greatly and this structure brings convenience for maintenance and assembling.
