Abstract
The utility model relates to a multi-functional valve cover for single-cylinder diesel engine suitable for the carrier vehicle provided with a diesel engine, which is an improvement to the prior art. A connecting bolt 7 is arranged in an indication oil scale ole 2 and the embossments are arranged at the left side of a positioning screw hole 3 and on the external surface of a cover body which is arranged at the upper part of the indication oil scale hole 2; a main oil canal 8 which is opposite to and communicated with a main oil canal 1 and a pressure limiting valve hole 9 which is vertical to and communicated with the main oil canal 8 are arranged in the embossments; a pressure limiting valve 10 is arranged in the pressure limiting valve hole 9 and an oil filler hole 11 is arranged on a cover body which is arranged below the pressure limiting valve hole 9; a pressure-relief vent b4 is arranged on a cover body which is arranged below the main oil canal 8 and two oil spray holes 12, 13 which are communicated with the pressure limiting valve hole 9 are arranged on the hole wall of the pressure limiting valve hole 9 which is arranged at the internal side of the cover body. The multi-functional valve cover for single-cylinder diesel engine has an important meaning to improving the lubrication of the machine body of the engine, lowering the machine oil consumption, enhancing the integral technical performance, being convenient for the maintenance and extending the service life of the engine.
Description
Technical field:
The utility model relates to, be applicable to the multi-functional valve cover of a kind of single cylinder diesel of installing and using on the single cylinder diesel transport vehicle.
Background technique:
The single cylinder diesel transport vehicle, because its small and exquisite, cheap, characteristics such as easy to operate are subjected to liking of vast farmers friend deeply, the owning amount in China rural area rapidly increases, and is the good assistant that friend peasant gets rich.But because the structural design of single cylinder diesel valve cover is not too reasonable, influenced the comprehensive technical performance and the usability of single cylinder diesel transport vehicle, brought inconvenience also for maintenance and maintenance, thereby the driving accident that causes has also happened occasionally.The major defect of this valve cover is: 1, the oil ga(u)ge in the indication oil ga(u)ge hole can only show that inorganic oil is arranged in the cylinder, can not judge oil level and engine oil pressure in the cylinder, oil ga(u)ge is installed in the motor rear portion, vehicle driver under steam be cannot see oil ga(u)ge at all, if machine oil adding too much can causing machine oil is scurried burning, not only increased the consumption of machine oil, also be easy to generate carbon deposit, made component impaired; If machine oil is very little, can not set up enough pressure because of oil-collecting quantity not sufficient lubricating oil path, can cause insufficient lubrication and aggravate the wearing and tearing of moving parts, seriously can cause accidents such as seize tile kilning.2, do not have oil hole on the valve cover, oil hole is located at engine front cover and covers, and the driver goes under will getting into car during oiling, and operating difficulties is wasted time and energy.3, no pressure-limit valve on the cover can't be adjusted engine oil pressure, does not guarantee that bent axle, main bearing, the normal of connecting rod bearing lubricate.
Summary of the invention:
For overcoming the deficiency that prior art exists, the utility model will be improved prior art, its specific practice is: remove the oil ga(u)ge that is provided with in the indication oil ga(u)ge hole in the prior art, in indication oil ga(u)ge hole, establish a connecting bolt, make it be connected fork-like farm tool used in ancient China with intuition table in the operator cabin and react oil level and engine oil pressure in the cylinder body by high-pressure oil pipe; For regulating the pressure of machine oil, on the outer surface of the top cover body in the left side of positioning screw hole, indication oil ga(u)ge hole, be provided with projection, in convex portion, set up relative with original main oil gallery and a communicate main oil gallery and pressure limiting valve opening vertical with the main oil gallery that increases newly and that communicate, be provided with a pressure-limit valve in the pressure limiting valve opening, on the inboard pressure-limit valve hole wall of cover body, be provided with two nozzle openings that communicate with the pressure limiting valve opening; Refuel for convenience, on the cover body below the pressure limiting valve opening, be provided with an oil hole.
The multi-functional valve cover of single cylinder diesel of the present utility model has reasonable in design compared with the prior art, improves body lubricating, improves engine efficiency, reduces machine oil and expends, and improves starting performance, prevents the seize tile kilning, and convenient for maintaining etc. are multi-functional.Its realization for improving the comprehensive technical performance and the usability of single cylinder diesel transport vehicle, prolongs the working life of motor, reduces maintenance expenses, and convenient for maintaining and maintenance provide the guarantee on the goods and materials.
