Abstract
The utility model discloses a four-valve cylinder head for a water-cooling engine, which is characterized in that: two seating rings (2) of an inlet valve and two seat rings (3) of an exhaust valve are arranged at the inner wall of a combustion chamber (8); at least one water inlet hole (7) is arranged at the joint surface for the cylinder head (1) and the cylinder block; water jackets (5) are arranged at periphery of the seating ring (2) for the inlet valve, the seat ring (3) of the exhaust valve and the spark plug (4); a water outlet (6) is arranged at lateral face of the spark plug (4); the combustion chamber (8) is arranged at the central section of the cylinder head (1); at least one air vent (9) is arranged at lateral face of the cylinder head (1). The utility model has the advantages of good cooling effect, power performance increase, low fuel consumption and ability of lowering environmental pollution.
Description
(1). technical field
The utility model belongs to engine art, particularly a kind of cylinder head that is used for cooling engine for motor cycle water.
(2). background technique
At present.Adopt air-cooledly in the type of cooling of the cylinder head of the motorcycle engine of the middle or small discharge capacity of motorcycle, this method is owing to be natural air cooled, so cooling effect is bad, make engine heat load big, power performance descends, the oil consumption height, oil firing is incomplete, causes environmental pollution.
(3). summary of the invention
The purpose of this utility model provides a kind of water cooled engine four valve cylinder heads.Its good cooling results, power performance increases, and oil consumption is low, can reduce environmental pollution.
For reaching above-mentioned purpose, the utility model comprises cylinder head, inlet valve seat ring, exhaust valve seat insert, spark plug and firing chamber, the inwall that it is characterized in that the firing chamber is provided with 2 inlet valve seat rings and 2 exhaust valve seat inserts, the junction plane of cylinder head and cylinder block is provided with at least one water inlet, is provided with water jacket around inlet valve seat ring, exhaust valve seat insert and the spark plug, and the side of spark plug is provided with water outlet, the firing chamber is positioned at the middle part of cylinder head, and the side of cylinder head has a relief opening at least.
The utility model is owing to be provided with water jacket around engine cylinder head, can be cooled with circulating water cylinder head, therefore rate of cooling is fast, effective, engine power performance is improved, power improves 15%, and moment of torsion improves 20%, and fuel combustion is abundant, oil consumption reduces by 10%, can reduce environmental pollution.
Below in conjunction with accompanying drawing the utility model is described further.
(4). description of drawings
Fig. 1 is the plan view of the utility model cylinder head;
Fig. 2 is the worm's eye view of the utility model cylinder head;
Fig. 3 be among Fig. 2 along A-A to sectional view.
(5). embodiment
Referring to Fig. 1 and Fig. 2.Junction plane in cylinder head 1 and cylinder block is provided with 4 water inlets 7, be provided with water jacket 5 around inlet valve seat ring 2, exhaust valve seat insert 3 and the spark plug 4, the side of spark plug 4 is provided with water outlet 6, firing chamber 8 inwalls are provided with 2 inlet valve seat rings and 2 exhaust valve seat inserts, and cylinder head 1 has a relief opening 9 at least.
When motor is started working, cooling water enters cylinder head 1 from 4 water inlets 7 through water jacket 5, and cooling water is pooled to the water jacket 5 (referring to Fig. 3) of cylinder head 1 around inlet valve seat ring 2, exhaust valve seat insert 3 and spark plug 4, to thermostat and radiator, the temperature of cylinder head 1 is descended through water outlet 6.
8 inwalls are provided with two 2 inlet valve seat rings and 2 exhaust valve seat inserts to the utility model in the firing chamber, in the side of cylinder head 1 relief opening 9 is arranged, can make the cylinder air inlet more abundant, exhaust is more thorough, burning indoor exhaust air less residue, engine power performance increases.
The side of the utility model cylinder head 1 is provided with two relief openings 9, can make cylinder reach above-mentioned effect equally.
