Description
Technical field
The utility model relates to a kind of cylinder head.
Background technique
Cylinder head is provided with the firing chamber, intake duct that communicates with the firing chamber and air outlet flue, and what communicate with the firing chamber is used for suction valve cone hole and exhaust valve seat hole, and the binding site in firing chamber and suction valve cone hole and exhaust valve seat hole is provided with air valve seat ring; Cylinder head top be provided with the cavity that is used to hold inside components such as valve, valve rocker, this cavity is surrounded by four sidewalls basically, smooth excessiveness between each sidewall; The top of sidewall is in same plane, and four angles on this plane are provided with the screw that is connected with cylinder-head cover; Surround on the sidewall of cavity and be provided with some radiating fin.Obviously, surround the sidewall height of cavity other parts, promptly greater than the top, firing chamber of cylinder head and the thickness of position hand air outlet flue one side greater than its cylinder head on one side.So the thickness over against the cylinder head on top, firing chamber is different, the thickness that leans on intake duct one side approximately is 4 times near air outlet flue one side thickness, this has just caused the thermal capacity of cylinder head each several part inconsistent, promptly than the thermal capacity of thickness portion thermal capacity greater than thin part, and cylinder head is in the condition of high temperature in the firing chamber when in running order, make from the heat heat radiation inequality of firing chamber conduction because the thermal capacity of cylinder head each several part is inconsistent, and then make that the thermal distortion of cylinder head each several part is inconsistent, finally cause the distortion that occurs blowing up of the thin place of cylinder head on top, firing chamber, make that the cylinder head attachment face applying of cylinder head and cylinder block is not tight, cause the decreased performance of motor; On the other hand, also because the thermal distortion of cylinder head each several part distortion is inconsistent, can cause the loosening of air valve seat ring, this can cause the decreased performance of motor equally.
Cylinder head is provided with four and is used for the through holes that bolt connects cylinder block, and wherein two are arranged in the described cavity and near two corners of intake duct one side, in addition on the boss of two both sides that are arranged on air outlet flue.Be provided with the suction valve cone hole and the gate seat hole of giving vent to anger in described inside cavity, be provided with in a side correspondence of these two valve-seat bores and be used to the screw intake rocker being installed and being given vent to anger rocking arm.For gaining in strength, suction valve cone hole, the gate seat hole of giving vent to anger, intake rocker screw, the rocking arm screw of giving vent to anger are separately positioned on the boss, so have groove between each boss.Because the existence of these grooves makes that also became uneven appears in cylinder head, aforesaid reason, this also can cause the decreased performance of motor.
In described cavity, be provided with oil inlet hole near intake valve one side, be provided with oil outlet near exhaust valve one side, thus lubricant oil can be in cavity the parts in the circulating lubrication cavity.But when lubricant oil is spurted into cavity,, make that machine oil burning specific consumption is bigger, thereby the performance of motor is reduced, discharge also relatively poor because therefore oil inlet hole and intake valve close together have parts of lubricating oil and enter in the firing chamber.
