Abstract
The invention discloses an engine cylinder head with a spark plug cooling channel, wherein the cylinder head is provided with a combustion chamber, a gas inlet channel, a gas outlet channel, and a vent channel; the gas inlet channel and the gas outlet channel are communicated with the combustion chamber; the surface of the combustion chamber is provided with a gas inlet, a gas outlet and a spark plug mounting hole; the other end of the spark plug mounting hole is reserved on the wall of the vent channel; the outer surface of the cylinder head is provided with a plurality of transverse radiating fins; the longitudinal retaining walls are arranged between the radiating fins at the mounting side of the spark plug of the cylinder head; and the retaining walls, the outer wall of the cylinder head and the radiating fins form a lateral cooling air channel. The invention comprises a special cooling channel near the mounting part of the spark plug, and therefore, cooling air can directly pass through the special cooling channel without entering into the cylinder head, so as to introduce fresh cold air to effectively cool spark plug and the parts around spark plug, thereby confirming great performance of the spark plug.
Description
Technical field
Invention relates to a kind of engine cylinder head, particularly a kind of engine cylinder head with the spark plug cooling channel.
Background technique
At present the engine cylinder head on the motorcycle is the sealing of cylinder top, and forms the firing chamber of motor jointly with piston head and cylinder wall.Except that the firing chamber, on cylinder head, also offer intake duct, air outlet flue, ventilation flue and spark plug mounting hole, spark plug mounting hole is positioned at ventilation flue and communicates with the firing chamber, and it is used to install spark plug.Intake duct and air outlet flue and cylinder head firing chamber are crossing to be passed through, and forms inlet hole and exhaust port at combustor surface.The cylinder head outer surface is provided with many radiating fin, to increase the heat diffusion area of cylinder head, guarantees that motor is able to abundant heat radiation.
Only have the ventilation flue that is used for cooling combustion chamber and spark plug on the existing cylinder head, and cooling air is to arrive spark plug again through the firing chamber earlier by this ventilation flue, thereby make spark plug can only lean on the hot air behind the cooling combustion chamber to cool off, cooling effect is very undesirable.
Summary of the invention
In order to overcome the deficiencies in the prior art, invention provides a kind of engine cylinder head with the spark plug cooling channel.
Invention solves the technological scheme that its technical problem adopted:
A kind of engine cylinder head with the spark plug cooling channel, offer the firing chamber on the described cylinder head, intake duct, air outlet flue and ventilation flue, described intake duct and air outlet flue communicate with the firing chamber, the surface of described firing chamber forms inlet hole and exhaust port and spark plug mounting hole, the other end of spark plug mounting hole is opened in the ventilation flue wall, described cylinder head outer surface is provided with several horizontal radiating fin, it is characterized in that: described cylinder head is provided with barricade longitudinally between the radiating fin of spark plug installation side, and this barricade and cylinder head outer wall and radiating fin form the side cooling air passway;
As improvement of the technical scheme, described barricade is obliquely installed and points to the spark plug mounting point.
As further improvement in the technical proposal, described cylinder head offers air inlet duct in the air outlet flue side, and this air inlet duct is connected with described ventilation flue.
The beneficial effect of the invention is: invention has designed special-purpose cooling channel near the mounting point of spark plug, make cooling air directly not need to enter cylinder head by special-purpose cooling channel, cooling air is built up ground applying cylinder head outer wall and is passed through, have attached good cooling effect and blow to spark plug, thereby introduce fresh cold air to spark plug and effectively cool off on every side, guarantee that spark plug work is good; The cooling channel of spark plug special use utilizes radiating fin to add barricade and forms, and design is fried ingeniously, and structural modification is little, easy processing; In addition, barricade connects the adjacent radiating fin of spark plug installation side, to the radiating fin bracing reinforcement, reduces its chatter and noise.
Description of drawings
Below in conjunction with drawings and Examples invention is further specified.
Fig. 1 is the structural representation of invention;
Fig. 2 is the structural representation of invention other direction;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of engine cylinder head with the spark plug cooling channel, offer firing chamber 1 on the described cylinder head, intake duct 2, air outlet flue 3 and ventilation flue 4, described intake duct 2 and air outlet flue 3 communicate with firing chamber 1, the surface of described firing chamber 1 forms inlet hole 21 and exhaust port 31 and spark plug mounting hole 5, the other end of spark plug mounting hole 5 is opened in ventilation flue 4 walls, cylinder head has air inlet duct 6 in air outlet flue 3 sides, air inlet duct 6 is connected with described ventilation flue 4, described cylinder head outer surface is provided with the radiating fin 7 of several cross settings, described cylinder head is provided with barricade 8 longitudinally between the radiating fin 7 of spark plug installation side, barricade 8 connects support with adjacent two radiating fin, and make radiating fin 7, barricade 8 forms a side cooling air passway 9 with the cylinder head outer wall, make and can outwards not disperse by the cooling air of radiating fin 7, pass through but build up ground applying cylinder head outer wall, have attached good cooling effect and blow to spark plug, make spark plug and effectively cooling on every side thereof.
This product is in order to obtain better cooling effect, and described barricade 8 is obliquely installed and points to the spark plug mounting point, makes cooling air blow to spark plug.
Invention has designed special-purpose cooling channel near the mounting point of spark plug, make cooling air directly not need to enter cylinder head by special-purpose cooling channel, thereby introduce fresh cold air to spark plug and effectively cool off on every side, guarantee that spark plug work is good; The cooling channel of spark plug special use utilizes radiating fin to add barricade and forms, and design is fried ingeniously, and structural modification is little, easy processing; In addition, barricade 8 connects the adjacent radiating fin 7 of spark plug installation side, to radiating fin 7 bracing reinforcements, reduces its chatter and noise.
