Description
Technical field
The utility model belongs to engine cylinder head, is specifically related to be designed with the tappet machine cylinder head in air channel.
Background technique
Existing cylinder of motorcycle engine comprises cylinder head body, offers firing chamber, spark plug mounting hole, valve mounting hole, spill port and cooling duct on cylinder head body.Wherein, the effect of cooling duct is: when motorcycle driving, cylinder head cool air around enters in cylinder head body by cooling duct, and the heat of cylinder head body interior is taken away, to reach the effect of cooling heat dissipation.But because the cooling duct of existing cylinder head generally only has one, and the cross section of suction port is less, the throughput and the airspeed that make to enter cooling duct are very limited, thereby do not reach good cooling heat dissipation effect.
Summary of the invention
The purpose of this utility model is to provide a kind of motor three-way air conduit cylinder head, can promote distributing of cylinder head heat, improves the cooling effect of cylinder head.
A kind of motor three-way air conduit cylinder head described in the utility model, comprise cylinder head body, on cylinder head body, offer spark plug mounting hole, two valve mounting holes and two spill ports, on cylinder head body, along two valve mounting hole arranged direction, offer the first air channel, its cylinder head body between valve mounting hole and spill port, pass, and cylinder head body is connected; On cylinder head body, also offer the second air channel, it is communicated with between two valve mounting holes and with the first air channel, and the opening in the second air channel is positioned on the nearest cylinder head side of the described spark plug mounting hole of distance, and the aperture of described spark plug mounting hole is communicated with the second air channel; It is diminishing tubaeform that the intake grill in described the first air channel is, and the setting that is tilted to the left of the outer end of intake grill.
The centre line L 1 of described intake grill is 25 °～45 ° with the angle α of the centre line L 2 of cylinder head body, has fully guaranteed to enter throughput and the airspeed in air channel.
The beneficial effect of motor three-way air conduit cylinder head described in the utility model:
(1) adopt two air channel cooling air cylinder heads, the first air channel is that front and back connect, and when motorcycle driving, can guarantee that a large amount of air enters the first air channel; The opening in the second air channel can also play air inlet function when motorcycle bends to right, and makes more cold airflow enter cylinder head, thereby has promoted well distributing of cylinder head heat, effectively reduces the cylinder temperature of motor three-way air conduit cylinder head;
It is diminishing tubaeform that the intake grill in (2) first air channels is, and the outer end of intake grill is obliquely installed to spill port side (left), by this structure, can fully absorb the air-flow from 60 ° of angular range, make throughput and the airspeed in air channel obtain enough assurances, a large amount of throughputs is taken away the heat of cylinder head body interior, under equal operating conditions, the cylinder temperature of described motor three-way air conduit cylinder head is lower 6～8 ° than existing cylinder head, has reduced the consumption of machine oil; When high engine speeds turns round, the machine oil of process cylinder head can access fully cooling, thereby has reduced the parts wear of motor, has improved the heat dissipation characteristics of motor, has improved the service behaviour of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of motor three-way air conduit cylinder head described in the utility model;
Fig. 2 is along the sectional view of A-A line in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Motor three-way air conduit cylinder head as depicted in figs. 1 and 2, comprise cylinder head body 1, on cylinder head body 1, offer spark plug mounting hole 2, two valve mounting holes 4 and two spill ports 6, on cylinder head body 1, along two valve mounting hole 4 arranged direction, offer the first air channel 5, its cylinder head body 1 between valve mounting hole 4 and spill port 6, pass, and cylinder head body 1 is connected; The intake grill 5a in described the first air channel 5 is diminishing tubaeform, and the outer end of intake grill 5a is obliquely installed to spill port side (left); Be obliquely installed and the intake grill 5a of flare can fully absorb the air-flow from 60 ° of angular range, make throughput and airspeed in air channel can access enough assurances.A large amount of throughputs is taken away the heat of cylinder head body interior, under equal operating conditions, the cylinder temperature of described motor three-way air conduit cylinder head is lower 6～8 ° than existing motor three-way air conduit cylinder head, when high engine speeds turns round, the machine oil of process cylinder head also can access fully cooling, has reduced the consumption of machine oil, thereby has reduced the parts wear of motor, improve the heat dissipation characteristics of motor, improved the service behaviour of motor.As preferably, the angle α of the center line of the center line of described intake grill 5a and cylinder head body 1 is 35 °.On cylinder head body 1, also offer the second air channel 3, it is communicated with between two valve mounting holes 4 and with the first air channel 5, and the opening in the second air channel 3 is positioned on the nearest cylinder head side of the described spark plug mounting hole 2 of distance, and the aperture of described spark plug mounting hole 2 is communicated with the second air channel 3.The opening in the second air channel 3 can also play air inlet function when motorcycle bends to right, and makes more cold airflow enter cylinder head, thereby has promoted well distributing of cylinder head heat, has improved the cooling effect of cylinder head.
The centre line L 1 of the 5a of intake grill described in the utility model also can be 30 ° with the angle α of the centre line L 2 of cylinder head body 1, or is 25 °, or is 40 °, or is 45 °.
