The control device has the advantages that reciprocating motion of the piston of an engine is utilized for achieving the control over the opening and closing of the lubricating hole, therefore, the lubricating oil concentration when the piston of the engine works is ensured, and the function of prolonging the service life of a large-displacement cylinder is achieved.
Description
Technical field
The present invention relates to the cylinder oil control gear of gasoline four-stroke engine, is the control gear that a kind of piston synchronous negative pressure is controlled lubrication hole concretely.
Background technique
Horizontal engine of motorcycle, its cylinder top rear is near the position of crankcase, not in place because of the lubricant oil splash, causes cylinder to be pulled near piston and the cylinder of air inlet one side, has a strong impact on the working life of cylinder.
The claimant is in the patent of invention of application on July 16th, 2012, a kind of novel cylinder that the patent No. is 2012102452023, the problem of pulling at piston and the cylinder of solution cylinder air inlet one side is well solved, due to, piston is in up process, lubricant oil still enters cylinder by lubrication hole, and the running resistance while causing descent of piston increases, and causes the drawback of oil consumption rising 1%.
Under load operation, need more lubricant oil because of large-duty engine, and when normally travelling, too much lubricant oil will cause the piston running resistance to increase, and cause the drawback that oil consumption is risen.
Summary of the invention
The object of the present invention is to provide a kind of piston synchronous negative pressure to control the control gear of lubrication hole, there is the concentration of lubricating oil of piston when acting of effective assurance motor, reach the large discharge capacity cylinder of the prolongation function in working life.
The present invention realizes with following technological scheme: this kind of piston synchronous negative pressure is controlled the control gear of lubrication hole, and its structure comprises: radiating fin, cylinder sleeve, casing wall, fastener hole, lubrication hole, oil guide slot, valve block, piston, spring, pore.It is characterized in that, the turn right position of 10mm ~ 20mm of cylinder sleeve top left side is drilled with the lubrication hole of a logical eye, be designed with a pore at casing wall in cylinder sleeve, pore passes straight through to lubrication hole, the inside of pore is equipped with piston, piston is connected with valve block by pull bar, and spring one end withstands piston, and the other end withstands cylinder sleeve.
When the piston stroking upward of motor, produce negative pressure in crankcase, up along with the piston of motor, negative pressure is along with increase, when the skirt section of the piston of motor, covers pore, and the gas in pore is taken out of, the elastic force that piston overcomes spring moves right, and lubrication hole is closed by valve block;
When the descent of piston of motor, negative pressure in crankcase disappears, piston top in the spring handle pore goes back to the left side, valve block leaves lubrication hole, the lubricant oil gushed out from connecting rod introduces by oil guide slot the air inlet side one side that lubrication hole arrives the piston of motor, and the piston driving lubricant oil of motor makes air inlet one side of the piston of cylinder and motor all cover one deck oil film;
So circulation, thus the concentration of lubricating oil of piston when acting of motor effectively guaranteed.
Beneficial effect is that the present invention has the to-and-fro motion by the piston of motor, realizes the control to the open and close of lubrication hole, thereby guarantees the concentration of lubricating oil of piston when acting of motor, reaches the large discharge capacity cylinder of the prolongation function in working life.
