Fig. 1 shows the cylinder cap of the put-put that the utility model provides, this cylinder cap comprises cylinder cap body, described cylinder cap body comprises exhaust side, air inlet side, side, front end, bottom plane, end face and firing chamber, be provided with first passage 1 in the described air inlet side of the corresponding cylinder cap body of cylinder body air inlet side bolt hole to communicate, described first passage 1 communicates with the second channel 2 on described air inlet side, described second channel 2 communicates with third channel 3 downward in the oil pocket of described cylinder cap body, described third channel 3 communicates with the four-way 4 of the side, described front end of described cylinder cap body, described four-way 4 communicates with the prone Five-channel 5 in described top of described cylinder cap body, described Five-channel 5 communicates with camshaft through hollow camshaft bearing cap, the first steel ball oil stifled 6 for sealing is provided with in described second channel 2, the second steel ball oil stifled 7 for sealing is provided with in described third channel 3.
Cylinder cap body main oil gallery adopts compact structure design, the machine oil come from cylinder body imports to cylinder cap by air inlet side bolt hole 100, and imported to from the second channel 2 of air inlet face processing by first passage 1, second channel 2 is connected with the third channel 3 processed downwards from cylinder cap oil pocket.Machine oil enters into the four-way 4 of coming in from the processing of cylinder cap front-end face by third channel 3, and enters the Five-channel 5 processed from top surface of cylinder cover downwards from four-way 4.Machine oil enters into finally by Five-channel 5 camshaft that then camshaft-bearing cap enters into hollow, realizes the lubrication to camshaft bearing journal.This oil channel structure adopts the mode of directly processing on cylinder body, avoids traditional special mode of casting a special oil duct on cylinder body, namely alleviates weight, in turn ensure that the compact of structure.Simultaneously to second channel 2 and third channel 3, use the mode of the first steel ball oil stifled 6 and stifled 7 sealings of the second steel ball oil, but not conventional threads blocking adds the sealing means of sealer, namely simplifies technique, again reduces cost.
The described air inlet side of described cylinder cap body is provided with the first gas-entered passageway 8, second gas-entered passageway 9, the 3rd gas-entered passageway 10 and the 4th gas-entered passageway 11, article four, gas-entered passageway merges into the first little total gas-entered passageway 12 and second little total gas-entered passageway 13 between two before extending to described firing chamber, and described first little total gas-entered passageway 12 and second little total gas-entered passageway 13 directly communicate with described firing chamber.
Namely adopt combination type at air inlet place, the firing chamber punishment close to cylinder cap body becomes two independently air flues.Gas is from the first gas-entered passageway 8, second gas-entered passageway 9, 3rd gas-entered passageway 10, after 4th gas-entered passageway 11 enters into cylinder cap body, two independently the first little total gas-entered passageway 12 and second little total gas-entered passageways 13 are divided into before firing chamber will be entered, this structure both ensure that the reduction of intake resistance in intake process, simultaneously owing to being divided into two independently gas ports at entrance, be conducive to increasing air inlet area, improve intake efficiency, also can play simultaneously and increase combustion chamber charge eddy current, increase firing chamber flame velocity of propagation, improve the effect of burning, thus play the effect improving motor discharge and reduce engine consumption.
Described firing chamber inner bottom part is provided with the first boss 14 and the second boss 15.Described first boss 14 and the second boss 15 shaping with described firing chamber integrally casting.
Cylinder cap body casts two boss in a combustion chamber by adopting, and carrys out control combustion room volume by the mode measuring boss height.First boss 14 and the second boss 15 are two the casting boss be arranged in bottom the combustion chamber, because boss is directly by firing chamber die casting and molding, as long as therefore ensure that the combustion chamber volume on mould is no problem, just only need the control realizing combustion chamber volume by the height measuring these 2 boss when batch production.Compared with use volumetric measurement, technique simplifies greatly, and has saved cost.
The air inlet attachment face 18 of the exhaust flange face 16 of described exhaust side of described cylinder cap body, the water outlet attachment face 17 of side, rear end and air inlet side adopts convex type structure.
Bolt installation base 19,20,21 on described cylinder cap body is equipped with stiffening rib.
By the exhaust flange face 16 at cylinder cap body, rear end water outlet attachment face 17, air inlet attachment face 18 adopts convex type structural design, both ensure that sealing and the requirement of strength of attachment face, has also saved material and working area, reduced the weight of part.By to the bolt installation base 19,20,21 on cylinder cap body, adopt reinforcing rib structure design, the requirement of the installation strength of boss can be ensured, alleviate again the weight of part.
From actual effect, this structure, due to compact structure, is more conducive to the layout of motor, simultaneously because the aeration of motor is improved, better with the matching performance of car load.Complete-vehicle oil consumption reduces greatly, and emission performance also improves, and achieves the requirement of energy-saving and emission-reduction well.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
