Abstract
The present invention provides a rotary column type distribution device for engine. Said distribution device mainly is formed from rotary column body with duct channels and driven wheel and shell body covering the rotary column body and duct channels and possessing an intermediate air cavity communcated with engine inlet, outlet and engine cylinder body. In the course of rotation of said rotary column body, said invention uses the duct channels to respectively make air inlet communicate to intermediate air cavity, and then make the internmediate air cavity communicate to outlet so as to implement admission, compression and exhaustion works of engine cylinder operation process, so that it can greatly simplify distribution process, and can reduce failure rate and raise working efficiency.
Description
The invention provides a kind of rotary columa type distributing device for engine, belong to technical field of engines.
Existing engine air distribution system is divided into intake duct and air outlet flue usually.In order to control air intake-exhaust, suction valve and outlet valve have been arranged again.The camshaft that suction valve and outlet valve are connected by the timing chain or the flute profile band of bent axle drives regularly finishes air inlet and exhaust, and fitting piston is finished the four-stroke acting.Because air inlet and exhaust valve is to drive and take a seat by spring by bent axle and rocking arm, air valve take a seat transfer and resonance phenomenon in bounce-back and the lifting process can appear when the limit that reaches at a high speed.When burning, make part heat expansions such as air valve in the high engine speeds to-and-fro motion, make air valve produce the gap, thereby engine noise is increased, part such as air valve bent axle is also high temperature resistant in addition, also needs lubricated and cooling.Hyundai Motor is in order to improve power, often adopt the way of lengthening air valve stroke and air valve quantity to improve the smooth degree of intake and exhaust, so that originally complicated mechanism is complicated more, and sometimes timing chain or flute profile band damage air valve fall into cylinder can billiards air valve and piston, cause bigger loss.Common engine need be lubricated, and has small amount of engine oil to scurry into cylinder sometimes, burns simultaneously with gasoline, has strengthened the exhaust gas discharging amount.In a word, the distribution device part of existing motor is many, mechanism's complexity, and power loss is big, and noise is big, needs lubricated and regular maintenance adjustment.
Purpose of the present invention is exactly for solving the problems referred to above of available engine gas distribution system, a kind of component is few, simple in structure, noise is little, easy care and design provides, particularly can avoid moment intersection dead point because of inlet and outlet, reduce the loss of available gas, improve the rotary columa type distributing device for engine of work doing efficiency.
The present invention is achieved in that it comprises the match rotating cylinder of follower of driving of the toothed belt of band and the camshaft actuated of motor or chain, form with the housing that is connected with cylinder on the rotating cylinder with the band circular hole and through circle hole sleeve, have the suction tude and steam outlet pipe and the inlet hole that is connected with cylinder, air outlet hole and the middle pore that make circular hole and motor on the housing, the arc distance between inlet hole and the middle pore and air outlet hole equate with arc distance between the middle pore.Have the duct groove that can be communicated with inlet hole and middle pore and after the several angle rotation, be communicated with air outlet hole and middle pore again on the rotating cylinder, the groove of duct At All Other Times that rotating cylinder rotates cuts off mutually with each pore, this duct groove can be the straight shape hole of passing rotating cylinder, it also can be the bending hole, can also be out at curve bath of the straight end of rotating cylinder one side or curve bath of the curved end, the axial length of duct groove and middle pore, inlet hole, air outlet hole is identical, when piston is moved from top to bottom, cylinder forms vacuum, rotating cylinder rotated middle pore was communicated with inlet hole this moment, suck mixed gas, finish intake stroke, the piston arrives lower dead center, rotating cylinder rotates closes inlet hole, piston moves from bottom to top to make and forms a sealed space in the cylinder, thereby compressed mixed gas, finish compression stroke, rotating cylinder continues rotation, and piston by the acting of spark ignitor mixed gas, promotes piston and moves downward when top dead center, finish working stroke, pore and air outlet hole in piston runs to lower dead center, and rotation is connected by rotation, piston is operation upwards, discharge waste gas after burning, finish exhaust stroke.Piston cooperates with rotating cylinder like this, finishes the four-stroke acting of motor.
Advantage of the present invention is: only change the moving motion of rotation with a few parts into regard to the to-and-fro motion that makes the common engine air valve, thereby reach simple in structure, power loss is low, and noise is little, removes regular maintenance adjustment from.And with existing common engine interchangeability is arranged, and can reduce the price of air distributing device greatly.
