Abstract
The present invention relates to a rotary double-cavity hollow shaft admission (exhaust) method for four-stroke internal combustion engine. Its core technique is distributing mechanism formed from fixed external cover, rotary double-cavity hollow shaft, roller beairng and driven gear (or worm gear). Two parallel rectangular admission (exhaust) channel holes are cut on the middle position of the wall body of said fixed external cover, communicated with combustion chamber and fixed, and the central position of the described rotary double-cavity hollow shaft is equipped with an intermediate partition wall, in which one hollow cavity has an opened window for exhaust, and another hollow cavity also has an opened window for admission.
Description
Technical field: a kind of rotary dual-cavity hollow shaft that is used for four-stroke ic engine of the present invention advances (row) gas method, particularly respectively leaves an exhaust window and air inlet window on the wall body that has as the hollow cavity of the septate rotary dual-cavity hollow shaft in the centre of ring.When the rotary dual-cavity hollow shaft whenever rotates a circle, just can for the cylinder exhaust in time of motor once with air inlet once.
Background technique: in present explosive motor, the exhaust of motor, air inlet all have been to use the gas distribution system of air door body and tappet structure, yet the cylinder of this internal-combustion engine is when air inlet and exhaust, the circular tack of air door body is from the air inlet and the exhaust that have just hindered cylinder in passage, make that cylinder exhaust when work is not smooth, the air inlet deficiency.The power of this motor has been difficult to increase at present again.
Summary of the invention: a kind of rotary dual-cavity hollow shaft that is used for four-stroke ic engine of the present invention advances (row) gas method, and its core technology utilizes the rotation of the two-chamber hollow shaft that has into (row) transom window mouth to realize the expedite method of advancing (row) gas of explosive motor exactly.Thereby improved the power of motor.The distribution device of this method is made up of fixed jacket, rotary dual-cavity hollow shaft, roller-type bearing and driven gear (or worm gear), and fixed jacket is the alloy body of hollow cylinder.Have two on the wall body of the fixed jacket middle part side by side and rectangularly advance (row) gas port, this advances (row) mouth and directly communicates with the firing chamber of cylinder, and the oiling circular hole of two lubricant oil also will be arranged on the sidewall bodies of fixed jacket.Described rotary dual-cavity hollow shaft is exactly that central part at the hollow cylinder made from alloy is provided with an intermediate bulkheads as ring.Make a hollow cylinder be divided into two not connected hollow lumen, a hollow lumen is opened the need that a rectangular window is used for exhaust.Another hollow lumen is also opened the need that a rectangular window is used for air inlet.The opening length of the exhaust window of described rotary dual-cavity hollow shaft is to be centre point with the medial axis and to be the length that the opening number of degrees of (r+ δ) are split into exhaust window with the angle after exhaust advance angle (r) and exhaust delay angle (δ) addition, and width will adapt with cylinder block.And the opening length of air inlet window is to be centre point with the medial axis and to be the length that the opening number of degrees of (alpha+beta) are split into the air inlet window with the angle after intake advance angle (α) and intake lag angle (β) addition, and width will adapt in cylinder block.Open two circle oil leabs on the outer wall of described rotary dual-cavity hollow shaft, the effect of this oil duct can also be played the effect of sealing obtaining lubricating in the inwall that can make rotary dual-cavity hollow shaft cover in fixing.
Open a spline position on the outer rim wall body of the air inlet hollow lumen of described rotary dual-cavity hollow shaft, and then a driven gear (or worm gear) is installed.Therefore the power that driven gear (or worm gear) can obtain rotating from the timing gear on the bent axle just can make rotary dual-cavity hollow shaft circulate in the overlapping more than performance exhaust and the function of air inlet in fixing.
The gas distribution system of this inventive method can be embodied in rotary horizontal arranged in co-axial alignment h type engine h, h type engine h in upright arrangement, V-type engine, opposed h type engine h.
