Abstract
The utility model belongs to the technical field of engines, and particularly relates to a novel engine inlet valve. The novel engine inlet valve comprises a valve rod portion, a valve neck portion and a valve head portion, and a locking and clamping groove is arranged on a position close to the tail end of the valve rod portion. The novel engine inlet valve is characterized in that one end of the valve rod portion, close to the valve neck portion, is provided with a carbon deposit groove, the width of the carbon deposit groove is 5.9-6.1mm, and the depth of the carbon deposit groove is 0.4-0.6mm. The novel engine inlet valve aims to improve structure of the engine inlet valve and solve the problems that inflating volume of engines is insufficient and the inlet valve is stuck, and the problems are caused by carbon deposit on the valve head portion because of unreasonable structural design of the engine inlet valve.
Description
Technical field
The utility model belongs to technical field of engines, is specifically related to novel engine intake valve.
Background technique
Valve is a kind of vitals of motor, and the effect of valve is the waste gas after being responsible in motor input air specially and discharging burning.From engine structure, valve is divided into two kinds of intake valve and exhaust valves.The effect of intake valve is with in the air intake motor, burns with fuel mix; The effect of exhaust valve is that the waste gas after the burning is discharged and heat radiation.
Now present, the most structural design of the intake valve of motor is simple, although use comparatively convenient.Yet the intake valve head is easy to form carbon distribution, this not only so that the gas-entered passageway section greatly reduce, thereby affect the aeration quantity of motor, and then make in the firing chamber oxygen supply not enough, cause the vicious circle of carbon distribution deposition; And, be easy to cause intake valve stuck.In order to guarantee the normal operation of motor, people have to often the carbon distribution on the intake valve be struck off, and very trouble operates.
The model utility content
The purpose of this utility model: in order further to improve the structure of engine intake valve, available engine intake valve structural design is unreasonable to be caused intake valve head carbon distribution and brings the not enough and stuck problem of intake valve of motor aeration quantity to solve, and proposes novel engine intake valve.
The technical solution of the utility model: novel engine intake valve comprises engine valve stem, air valve cervix and valve head, and is provided with rod slot near the tail end of engine valve stem that it is characterized in that: described engine valve stem is provided with the carbon distribution groove near an end of air valve cervix; The groove width of described carbon distribution groove is 5.9mm～6.1mm, and its groove depth is 0.4mm～0.6mm.
Novel engine intake valve of the present utility model, owing to set up the carbon distribution groove on the original basis, thus increased the air inflow of gas-entered passageway, so that fuel oil or scurry into the lubricant oil sufficient combustion of cylinder has reduced the accumulation of carbon distribution.Such structural design is convenient to the removing of carbon distribution, and, be not easy to cause intake valve stuck, very easy to use.
Further, described carbon distribution groove is provided with the circular cone that width is 0.9mm～1.1mm near an end of air valve cervix.
The removing of carbon distribution is convenient in the design of circular cone, and is very easy to use.
Description of drawings
Fig. 1 is the embodiment's of novel engine intake valve of the present utility model structural representation.
Embodiment
As shown in Figure 1, the utility model provides novel engine intake valve, comprises engine valve stem 1, air valve cervix 2 and valve head 3, and is provided with rod slot 4 near the tail end of engine valve stem 1, and wherein, engine valve stem 1 is provided with carbon distribution groove 5 near an end of air valve cervix 2; The groove width of carbon distribution groove 5 is: B=5.9mm～6.1mm, and its groove depth is: C=0.4mm～0.6mm; One end of carbon distribution groove 5 close air valve cervixes 2 is provided with width and is: the circular cone of D=0.9mm～1.1mm.
In the present embodiment, the distance of the end face of the top of carbon distribution groove 5 and valve head 3 is: A=37.9mm～38.1mm.
Arranging of carbon distribution groove 5 is very crucial, and it has increased the air inflow of gas-entered passageway, so that fuel oil or scurry into the lubricant oil sufficient combustion of cylinder has reduced the accumulation of carbon distribution.Like this, on the one hand, be convenient to the removing of carbon distribution; On the other hand, reduced the stuck situation of intake valve.
Above-described only is preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
