Abstract
The utility model provides a water-cooled parallel double-cylinder head. The water-cooled parallel double-cylinder head has the scheme that a water sleeve (2), a water sleeve (21), and a water sleeve (22) are arranged in a combustion chamber (4), the installation hole (5) of a sparking plug, and circumference walls of an air discharge valve (11) and air inlet valve (12). The water sleeve (2), the water sleeve (21), and the water sleeve (22) are communicated with a water inlet (3), and are communicated with a water outlet (8) by water outlet passages (7). The water-cooled parallel double-cylinder head is adopted, and water cooling can be realized. The heat load of an engine is reduced by the water-cooled parallel double-cylinder head, the cooling effect of the engine is increased, and the power performance of the engine is increased.
Description
Technical field
The utility model relates to a kind of device of liquid cooling cylinder, the cylinder head of especially motorcycle water-cooled but motor.
Background technique
At present, the engine with two juxtaposed cylinders of motorcycle adopts blower cooled engine, its cylinder head also all adopts air-cooled cylinder head, but the heat load of part motor is higher, the cooling effect of its used heat is bad, especially around top, firing chamber, spark plug mounting hole, intake valve and the exhaust valve, these significant points are often too high because of temperature, influenced engine power performance.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of water-cooled cylinder head, to increase the cooling effect of motor, the lifting engine power performance.
Scheme of the present utility model is: be provided with water jacket in the surrounding wall of the firing chamber of cylinder head, spark plug mounting hole and exhaust valve, intake valve; This water jacket communicates with water intake and connects water outlet by water outlet; Cooling water just can be entered in each water jacket around top, cooling combustion chamber, spark plug mounting hole, intake valve and the exhaust valve by water intake like this, and it is too high and influence the normal operation of motor to make these significant points be unlikely to temperature.
Can connect mutually by exhaust valve water jacket intercommunicating pore, intake valve water jacket intercommunicating pore respectively between the described water jacket; Described water intake is along the firing chamber on the cylinder junction surface of cylinder head and distributes
The beneficial effects of the utility model are: because the transmission heat ability of water is than the air height, and in the firing chamber, around the spark plug, inlet and exhaust valve these significant points are provided with the cooling water water jacket, make cylinder head can reduce the heat load of motor, increase cooling effect, increase engine power performance.
