Abstract
A straight-through air channel on cylinder cover for the motorcycle's engine with forced air cooling features that the cooling air channel in cylinder cover has cooling air outlet, cooling air inlet and spark plug hole communicated to combustion chamber, and its main improvement is that a flow guide tube installed in cam chain chamber on cylinder cover is used to directly deliver the cooling air for carrying heat out in time and lowering the temp of spark plug's washer to less than 200 deg.C.
Description
Technical field
The present invention relates to motor, particularly relate to the improvement design of engine cylinder cap, mainly be applicable to motorcycle engine.
Background technique
Motorcycle has use flexibly, conveniently, to characteristics such as road worthiness are strong, is used widely." heart " parts of motorcycle are motors, and the performance of motor is determining the working life of motorcycle, and the main cause that influences engine life is the temperature of motor.Existing its cooling duct layout of motor is unreasonable, cooling air outlet is arranged on by the relief opening, section is little triangle, causing cooling air to turn round after the spark plug position enters cooling duct discharges from cooling air outlet again, the cooling air circulation has some setbacks, and can not be in time, take away in a large number with the heat at cylinder head position, thereby cause engine temperature higher, the spark-plug gasket temperature reaches as high as 250 ℃～260 ℃, therefore cause the engine mechanical performance to reduce, defectives such as cylinder wear increases, and oil consumption increases, and working life is short.
Summary of the invention
The present invention is in order to overcome the defective of prior art, provide a kind of cooling airflow logical forced air cold engine cylinder cover direct through type air flue smoothly, technological scheme is: be shaped on cooling duct in engine cylinder cap, cooling duct has cooling air import and cooling air outlet, open the logical firing chamber of system spark-plug hole in the cooling duct, it is characterized in that in the cam chain chamber of cylinder head honeycomb duct being installed, the honeycomb duct internal orifice leads to cooling duct, and the honeycomb duct collar extension is cooling air outlet.After improving design, it is straight-through with outlet that cooling duct in the engine cylinder cap becomes import, do not turn round, and the aperture is big, cooling air is directly discharged by honeycomb duct, thereby in time the heat at cylinder head position is taken away again morely, and the spark-plug gasket temperature is reduced to below 200 ℃, solve people and thirsted for for a long time reducing the engine temperature problem of too, obtained satisfied effect.
Description of drawings
Fig. 1 is that forced air cold engine cylinder cover of the present invention is shaped on the direct through type air flue structural representation.
Embodiment
The invention discloses a kind of improvement design of engine cylinder cap cooling duct, in engine cylinder cap 3, be shaped on cooling duct 2, cooling duct includes cooling air import 1 and cooling air outlet, the logical firing chamber 5 of spark plug is installed in spark-plug hole 4 in the cooling duct 2, because the cooling air outlet of prior art is arranged on by the relief opening, because of the restriction of structure, the aperture is little and turn round, so the cooling air circulation has some setbacks.Improvement project is the 10 liang of wall perforates in cam chain chamber with cylinder head, honeycomb duct 8 is installed therein, as shown in Figure 1, honeycomb duct 8 internal orifices and cooling duct 2 interpenetrate, honeycomb duct 8 collar extensions are cooling air outlet 9, make cooling duct straight-through, and can have through radiating fin 6 (but also can not having radiating fin 6), the cooling air circulation is very smooth and easy.Motor is at first installed cam chain when assembling, again honeycomb duct 8 is passed chain and fix, and can adopt fastening screw trip bolt 7 etc.In order to make cooling circulation better effects if, the center hole of honeycomb duct 8 can be positioned at the opposite, center of cooling air import 1.Big for the aperture that makes honeycomb duct 8, make and install more convenient, the inner hole section of honeycomb duct 8 can be made circle (but also can be other shape).
Claims (3)
1, forced air cold engine cylinder cover direct through type air flue, in engine cylinder cap (3), be shaped on cooling duct (2), cooling duct has cooling air import (1) and cooling air outlet, open the logical firing chamber (5) of system spark-plug hole (4) in the cooling duct, the middle honeycomb duct (8) of installing in cam chain chamber (10) that it is characterized in that cylinder head, the honeycomb duct internal orifice connects cooling duct (2), and honeycomb duct (8) collar extension is cooling air outlet (9).
2, forced air cold engine cylinder cover direct through type air flue as claimed in claim 1 is characterized in that honeycomb duct (8) position is on cooling air import (1) opposite, center.
3, forced air cold engine cylinder cover direct through type air flue as claimed in claim 1, the inner hole section that it is characterized in that honeycomb duct (8) are circular.
