Abstract
A kind of automobile engine combustion system is the utility model is related to, piston is equipped with engine combustion room, it is characterised in that：Corresponding valve position, combustion chamber inner side are equipped with the inclined-plane for being used for lifting Flow coefficient of inlet;Piston-top surface is correspondingly provided with inclined-plane, is engaged with the inclined-plane on the inside of the combustion chamber.
Description
Technical field
It the utility model is related to a kind of automobile engine combustion system.
Background technology
Ridge-roof type combustion chamber is the more common combustion-chamber shape of naturally aspirated engine, the combustion chamber of the shape not only face
Hold than small, and, spark plug connection and reasonable arrangement more reasonable with geometry, appropriate air motion can be organized and had enough
Intake and exhaust flow area the advantages that.Existing naturally aspirated petrol engine technology is developed so far, only by the whole hair of optimization
Motivation air inlet system and exhaust system are difficult to the charge flow rate coefficient for being obviously improved naturally aspirated engine, and then are difficult to further lifting and start
Machine performance.
Utility model content
The goal of the invention of the utility model is to provide a kind of automobile engine combustion system, by optimizing combustion chamber, into
One step lifts the performance of engine.
Realize the technical solution of the present utility model purpose：
A kind of automobile engine combustion system, is equipped with piston in engine combustion room, it is characterised in that：Corresponding valve position
Put, the inclined-plane for being used for lifting Flow coefficient of inlet is equipped with the inside of combustion chamber.
Further, piston-top surface is correspondingly provided with inclined-plane, is engaged with the inclined-plane on the inside of the combustion chamber.
Further, engine chamber is ridge-roof type combustion chamber.
The utility model has the advantage that：
The utility model corresponds to valve position, and the inclined-plane for being used for lifting Flow coefficient of inlet is equipped with the inside of combustion chamber；Profit
Guiding with inclined-plane to air-flow so that air-flow will not reduce discharge coefficient after combustion chamber is entered because of obstruction；Intake valve liter
When journey is in middle lift, since there is the sectional area of increase air-flow flowing in inclined-plane by intake valve, when improving middle lift
Flow coefficient of inlet, lifts engine volumetric efficiency, lifts the performance of engine.
The utility model piston-top surface is correspondingly provided with inclined-plane, is engaged with the inclined-plane on the inside of the combustion chamber.Under piston
When row is in expansion stroke, top land region forms squish area with combustion chamber valves side, formed with the flow field beneficial to burning, makes
Obtaining flame can propagate into squish area, reduce pinking tendency；Engine emission is reduced, lifts the efficiency of burning.
The utility model varies without ridge-roof type combustion chamber agent structure, designs advantages of simple, of low cost.

Fig. 1 is intended to for the utility model ridge combustion chamber；
Fig. 2 is existing ridge combustion chamber schematic diagram；
Fig. 3 is the utility model top land top view；
Fig. 4 is existing top land top view；
Fig. 5 is the utility model ridge combustion chamber bottom view；
Fig. 6 is existing ridge combustion chamber bottom view；
Fig. 7 is the utility model induction pathway schematic diagram；
Fig. 8 is existing combustion chamber charge path schematic diagram.
Embodiment
Circle note position in Fig. 1, Fig. 2, Fig. 7, Fig. 8 is the utility model and the difference position of existing ridge combustion chamber.Such as
Shown in Fig. 1, corresponding valve position, combustion chamber inner side is equipped with the inclined-plane for being used for lifting Flow coefficient of inlet.It is as shown in figure 3, living
Plug top surface is correspondingly provided with inclined-plane, is engaged with the inclined-plane on the inside of the combustion chamber, and the dash area in Fig. 3 represents piston-top surface
Inclined-plane.
As shown in fig. 7, due to being equipped with the inclined-plane for being used for lifting Flow coefficient of inlet, profit on the inside of the utility model combustion chamber
Guiding with inclined-plane to air-flow so that air-flow will not reduce discharge coefficient after combustion chamber is entered because of obstruction；Intake valve liter
When journey is in middle lift, since there is the sectional area of increase air-flow flowing in inclined-plane by intake valve, when improving middle lift
Flow coefficient of inlet, lifts engine volumetric efficiency.
Exemplary description has been carried out to the utility model above in conjunction with attached drawing, it is clear that the realization of the utility model and from
The limitation of aforesaid way, if the various improvement that the methodology of the utility model and technical solution carry out are employed, or without
Improve and the design of the utility model and technical solution are directly applied into other occasions, in the scope of protection of the utility model
It is interior.
