Abstract
The utility model discloses a silent double-ignition air-cooled cylinder head comprising a cylinder head substrate, a rocker-arm support on the cylinder head substrate, a combustion chamber in the cylinder head substrate, two spark plugs on the dome of the combustion chamber, and radiating fins on the outer side of the cylinder head substrate, wherein the radiating fins comprise horizontal radiating plates and vertical reinforcing rib plates; the two spark plugs are distributed on the two opposite sides of the cylinder head substrate; and ventilation holes are formed in the reinforcing rib plates between the spark plugs and the windward side of the cylinder head substrate, so that air channels through which air passes are formed between the spark plugs and the windward side of the cylinder head substrate. As the silent double-ignition air-cooled cylinder head has a simple structure, the cylinder head can be better cooled, the thermal deformation of the cylinder head can be alleviated to reduce noises, and thus the cylinder head tends to be silent in a work process. By virtue of the double spark plugs, the ignition efficiency and the ignition reliability of the spark plugs are higher.
Description
Technical field
The utility model relates to a kind of motorcycle cylinder head, relates in particular to a kind of motorcycle squelch type dual ignition air cooled cylinder head.
Background technique
Traditional air-cooled cylinder head mainly comprises firing chamber, the rocker arm bracket on matrix in matrix, matrix and is located at the outer radiating fin of matrix, and radiating fin is by the radiating fin of level with strengthen longitudinally gusset and consist of usually.But due in the course of the work, the heat that cylinder head produces is larger, and traditional air-cooled cylinder head radiating effect is poor, thereby makes the cylinder head heat distortion amount larger, causes the noise that produces in the course of the work also larger.Although people also by variety of way to the noise abatement of lowering the temperature of air-cooled cylinder head, effect is still not ideal, especially the cooling at cylinder head spark plug place is also very poor.And spark plug is in the process of lighting, and the heat that the mixed gas knocking fuel in cylinder produces is often very large, is easy to directly cause the temperature of cylinder head integral body to raise, and easily affects the normal operation of spark plug.And in the motorcycle traveling process, wind blows to cylinder head from the windward side of cylinder head, but owing to strengthening longitudinally stopping of gusset, wind can't directly blow to the position of spark plug, thereby can not be well the heat at spark plug and top of combustion chamber place be taken away, be to cause one of major reason that spark plug position temperature raises.
Simultaneously, traditional cylinder head all only is equipped with a spark plug, and during burning, then flame propagated to edge of combustion chamber from the plug ignition of firing chamber central authorities, and flame travel is far away; Simultaneously again because being subjected to the evenly limitation of burning, can't reach higher compression ratio when using fuel oil of the same race, the uniformity of mixed gas has also affected combustion performance greatly, the firing chamber can not get desirable even mixed gas, thereby make the fuel oil at all can't perfect combustion, the thermal efficiency is lower, and exhaust contaminant is also many.
The model utility content
For the prior art above shortcomings, the purpose of this utility model just is to provide a kind of squelch type dual ignition air cooled cylinder head, and radiating effect is better, and noise reduction is better, and makes plug ignition usefulness higher.
to achieve these goals, the technical solution adopted in the utility model is such: a kind of squelch type dual ignition air cooled cylinder head, comprise the cylinder head matrix, rocker arm bracket on the cylinder head matrix, firing chamber in the cylinder head matrix, be arranged on the spark plug of firing chamber dome and the radiating fin outside the cylinder head matrix, described radiating fin comprises Heat sink and the vertical reinforcement gusset that arranges of cross setting, it is characterized in that: described spark plug is two, and be distributed in cylinder head matrix phase right both sides, the position that dome in the firing chamber is corresponding with two spark plugs offers spark plug mounting hole, two spark plugs are arranged on the firing chamber dome by spark plug mounting hole, offer vent hole on the reinforcement gusset between the windward side of spark plug and cylinder head matrix, make and form the air channel that air feed passes through between the windward side of spark plug and cylinder head matrix.
Increase a spark plug at the dome of firing chamber, thereby can realize that dual ignition plug lights a fire to the firing chamber simultaneously, the probability that catches fire is doubled, thereby improve the usefulness of plug ignition, and then improve the reliability of igniting; Two spark plugs are lighted a fire simultaneously, and not only flame travel has shortened half, and two spark plug Fire explosion burnings simultaneously, form rapidly stronger eddy current, significantly accelerate propagation of flame speed, also greatly improved heat utilization ratio simultaneously, more easily realized smooth combustion; And, form quick burning and lean-burn, make mixed gas form more rationally, burn more abundant, thereby can reduce pollutant in exhaust.By offer vent hole on the reinforcement gusset between the windward side of spark plug and cylinder head matrix, when motorcycle is advanced, wind energy enough directly blows to spark plug and top of combustion chamber, thereby the heat that mixed gas knocking fuel in cylinder produces is directly taken away, can be lowered the temperature to spark plug and top of combustion chamber better; And then reduce cylinder head Yin Gaowen and the deformation that produces in the course of the work, thereby reduce the noise that cylinder head produces at work.
Further, be provided with the oil duct sound absorption cavity between the dome of firing chamber and rocker arm bracket, the top of described oil duct sound absorption cavity offers oil inlet hole, offers oil outlet at the sidepiece of oil duct sound absorption cavity.Owing to being provided with the oil duct sound absorption cavity, it has intercepted the direct transmission of firing chamber moment high temperature to rocker arm bracket, expands because of temperature rise rapidly the valve pin is touched the unfavorable situation that cause in the bolt gap thereby changed rocker arm bracket; Due to described oil duct sound absorption cavity top and sidepiece be provided with oily heat exchange into and out of oilhole, thereby make in cylinder cap; the uniformity that more becomes heats up for the rocking arm chamber; changed the serious uneven state of the inlet and outlet both sides rocking arm temperature rise that causes because of direct heat transfer; the oil body that flows downward has simultaneously not only absorbed the part noise, and the part heat is exchanged by crankcase; Thereby reduce better noise.
Further, also be provided with a depressed part to the formation of cylinder head matrix inner recess on the cylinder head matrix above spark plug mounting hole, described depressed part is between firing chamber dome and oil duct sound absorption cavity.Between firing chamber dome and oil duct sound absorption cavity, depressed part is set, the firing chamber dome can directly be contacted with air, the heat that produces can be taken away by air, thus better cylinder head is carried out cooling, with the noise that produces in further reduction cylinder head working procedure.
Compared with prior art, the utility model has the advantage of: simple in structure, can cool to cylinder head better, can reduce the heat distortion amount of cylinder head, thereby reduce noise, make in sending down abnormally ascending cylinder head working procedure more to be tending towards quiet; Adopt dual ignition plug, make that plug ignition usefulness is higher, reliability igniting is higher.
