Abstract
A vertical type double overhead camshaft motorcycle engine is characterized in that a drain hole is arranged at the bottom of a spark plug installation hole in a cylinder head of the engine, the connection position of the drain hole and the spark plug installation hole is located on the side wall of the spark plug installation hole, the end of the drain hole, which is communicated with the spark plug installation hole, is higher than the other end of the drain hole, and the drain hole communicates the spark plug installation hole with the outer side of the cylinder head. When accumulated water exists at the position of the spark plug installation hole, the accumulated water can flow out from the drain hole, so that the problem of breakdown of an ignition coil caused by the accumulated water at the position of the spark plug installation hole is solved.
Description
Technical field
The utility model relates to a kind of motorcycle engine, especially a kind of vertical Dual Over Head Camshaft motorcycle engine.
Background technique
Existing vertical motorcycle engine, when cylinder head combination was vertically arranged, rainwater easily was immersed in the spark plug mounting hole, caused spark plug and spark coil short circuit, spark plug was damaged or the spark coil puncture.
Existing Dual Over Head Camshaft motorcycle engine is for solving the lubrication problem of distribution cam axle in addition, generally make the pump oil of oil pump flow to cylinder head cover, lubricant oil flows into distribution cam axle via cylinder head cover, but such project organization is complicated, and easily causes leakage of oil.
The model utility content
The shortcoming that exists in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of vertical Dual Over Head Camshaft motorcycle engine, and it mainly is the spark coil breakdown problem of having avoided spark-plug hole place ponding to cause.
In order to address the above problem, the utility model is by the following technical solutions: a kind of vertical Dual Over Head Camshaft motorcycle engine, the bottom of the spark plug mounting hole in the cylinder head of motor is provided with spilled water hole, the link position of spilled water hole and spark plug mounting hole is positioned at the sidewall of spark plug mounting hole, the other end that end is higher than spilled water hole that is communicated with of spilled water hole and spark plug mounting hole, described spilled water hole will spark plug mounting hole and the cylinder head outside be connected.
Preferably: the diameter of described spilled water hole is 4mm.
In order further to solve the problem of the lubricating structure complexity of distribution cam axle in the prior art, the utility model also provides further technological scheme: be used for the lubricated oil duct of distribution cam axle in the motor and be comprised of the casing oil duct, the gentle cylinder head stud bolt of cylinder oil duct mounting hole, the valve cam hubcap oil duct that are communicated with successively, the oil outlet end of in-engine oil pump is communicated with described casing oil duct; Be provided with air inlet distribution cam axle lubricating point, exhaust distribution cam axle lubricating point on the described valve cam hubcap oil duct; On the lubricated order that the flow direction of lubricant oil produces, described exhaust distribution cam axle lubricating point is prior to air inlet distribution cam axle lubricating point.
Preferably, the wide 3mm of described valve cam hubcap oil duct, dark 2mm.
The beneficial effects of the utility model are:
1, having solved spark-plug hole place damages and the spark coil breakdown problem because of the spark plug that ponding causes.
2, simplify the distribution cam axle lubricating structure of Dual Over Head Camshaft motorcycle engine, avoided engine cylinder head to cause the problem of oil seepage oil because of pressure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the main sectional view at spark plug mounting hole place among the utility model embodiment;
Fig. 2 is the sectional view of bowing at spark plug mounting hole place among the utility model embodiment;
Fig. 3 is the structural representation that is used for the lubricated oil duct of distribution cam axle among the utility model embodiment;
Among the figure: 1 spark plug mounting hole, 2 spilled water holes, 3 oil pump, 4 casing oil ducts, 5 cylinder oil ducts, 6 cylinder head stud bolt mounting holes, 7 exhaust distribution cam axles, 8 air inlet distribution cam axles, 9 valve cam hubcap oil ducts, 91 exhaust distribution cam axle lubricating points, 92 air inlet distribution cam axle lubricating points, 10 casings, 11 cylinder heads.
Embodiment
Such as accompanying drawing 1, shown in Figure 2, a kind of vertical Dual Over Head Camshaft motorcycle engine, the bottom of the spark plug mounting hole 1 in the cylinder head 11 of motor is provided with spilled water hole 2, the link position of spilled water hole 2 and spark plug mounting hole 1 is positioned at the sidewall of spark plug mounting hole 1, the other end that end is higher than spilled water hole 2 that is communicated with of spilled water hole 2 and spark plug mounting hole 1, described spilled water hole 2 is connected spark plug mounting hole 1 and cylinder head 11 outsides, when there is ponding at spark plug mounting hole 1 place, can flow out from spilled water hole 2.The diameter of this spilled water hole is 5mm.
As shown in Figure 3, be used for the lubricated oil duct of distribution cam axle on this motor, formed by casing oil duct 4, cylinder oil duct 5 and the cylinder head stud bolt mounting hole 6, the valve cam hubcap oil duct 9 that are communicated with successively.
The oil outlet end of in-engine oil pump 3 is communicated with described casing oil duct 4.Be provided with exhaust distribution cam axle lubricating point 91, air inlet distribution cam axle lubricating point 92 on the described valve cam hubcap oil duct 9; On the lubricated order that the flow direction of lubricant oil produces, described exhaust distribution cam axle lubricating point 91 is prior to air inlet distribution cam axle lubricating point 92.Described valve cam hubcap oil duct 9 wide 3mm, dark 2mm has guaranteed the unimpeded of lubricant oil.
When lubricated, casing oil duct 4, the cylinder oil duct 5 cylinder on of oil pump pump oil from the casing 10 flow in the cylinder head stud bolt mounting hole 6 on the cylinder head 11, be flowed directly to valve cam hubcap oil duct 9 on the valve cam hubcap via cylinder head stud bolt mounting hole 6, a lubricant oil part flows out from exhaust distribution cam axle lubricating point 91 implements pressure lubrication to exhaust distribution cam axle 7, and another part continues to flow to air inlet distribution cam axle lubricating point 92 places air inlet distribution cam axle 8 is implemented pressure lubrication.
