Abstract
The utility model discloses a cylinder head of the four-stroke water cooling engine which forces the height and size of the cylinder head not to change in water-cooling reconstruction of the air-cooled engine with simple and effective arrangement of the water jacket and economical and practical mounting position of the water pump. The utility model comprises a combustion chamber, an inlet duct, an exhaust duct, a chain cavity, and a screw bolt hole used for connecting the cylinder body. The periphery of the combustion chamber is provided with a water jacket which is arranged on the outside of the screw bolt hole. The water jacket is provided with a water inlet communicated with the water outlet via hole of the cylinder body, and a water outlet draining the water from the cylinder head. The water outlet position is provided with a hole for mounting the thermostat. The chain cavity position is provided with a threaded hole for mounting the water pump. The cylinder head of four-stroke water cooling engine has low investment and fast effect in reconstruction and is especially applied to the water-cooling reconstruction of the air-cooled engine, having good water-cooling effect and simple mould manufacturing.
Description
One, technical field
The utility model relates to a kind of motorcycle engine parts, specifically a kind of four-stroke water cooled engine cylinder head.
Two, background technique
Four-stroke engine for motor cycle adopts forced air cooling usually at present, and its cooling effect does not have water-cooled good.When motor carries out the water-cooled transformation, consider the reason of reforming cost, often be unwilling to change the position, construction bolt hole of cylinder head and cylinder block and crankcase, and, the transformation of constituent often is subjected to the restriction that distribution device is arranged, will increase water jacket on the one hand, the height dimension of cylinder head is changed too much, make in order to avoid cause the change of distribution device to transform to become complicated.If change the bolt hole position, just must redesign crankcase, if change the height dimension of cylinder head, just must carry out dynamics Design again to distribution device, this will increase exploitation greatly and drop into and the cycle raising cost of production, the competitive ability of reduction motorcycle on market.
Three, summary of the invention
The purpose of this utility model provides a kind of forced air cold engine can not change cylinder head when water-cooled is transformed height dimension, and water jacket is arranged simple effective, the economical and practical four-stroke water cooled engine cylinder head in water pump mounting point.
The purpose of this utility model is achieved like this: a kind of four-stroke water cooled engine cylinder head, it comprises firing chamber, intake duct, air outlet flue, chain chamber and the bolt hole that is used for being connected cylinder block, it is characterized in that: around the firing chamber, be provided with water jacket, described water jacket is arranged in the outside of bolt hole and is provided with water intake and water outlet, is useful on the screw that water pump is installed at chain chamber peripheral hardware.Be provided with the thermostat mounting hole at the water outlet place.
When cylinder block adopted water-cooled, described water intake communicated with water outlet through hole in the cylinder block.
For improving the fuel atomization condition, reduce warm-up period, described water outlet and intake duct are arranged on the same side of cylinder head.
Compared with prior art, the utility model is between the bolt hole introducing cooling water the firing chamber bridge of the nose, be used for the cooling combustion chamber, and water jacket is arranged in beyond the bolt hole so that circulating water is drawn, simultaneously water outlet position, thermostat are designed in intake duct one side, can improve fuel atomization, reduce warm-up period, simultaneously by the camshaft actuated water pump, in place, chain chamber design water pump mounting point.Its advantage is: transform convenience, less investment, instant effect, and good water-cooling effect, mould manufacturing are simple.

Five, embodiment
A kind of four-stroke water cooled engine cylinder head described in the utility model, it comprises firing chamber 1, intake duct 2, air outlet flue 3, chain chamber 4 and is used for being connected the bolt hole 5 of cylinder block, in the firing chamber 1 around be provided with water jacket 6, water jacket 6 is arranged in the outside of bolt hole 5, on water jacket 6, be provided with the water intake 7 that communicates with water outlet through hole in the cylinder block and make water flow out the water outlet 8 of cylinder head, for improving the fuel atomization condition, reduce warm-up period, water outlet 8 and intake duct 2 can be arranged on the same side of cylinder head.8 places are provided with the thermostat mounting hole at water outlet, are provided with the screw 9 that is used to install water pump at 4 places, chain chamber, and water pump is by camshaft actuated.In the utility model, be used for connecting the position of bolt hole of cylinder block and crankcase and size without any change, the height of cylinder head does not change yet, and so just greatly reduces cost input and the transformation cycle of forced air cold engine when carrying out the water-cooled transformation.
