Abstract
The utility model provides an about the oblique air flue side combusion chamber of diesel engine which in characterized in that places this combustion chamber near the other or cylinder head of the side in diesel engine cylinderpiston top dead center in, have air flue and cylinder to communicate with each other, and the central line of this air flue or its at the tangent line in this air flue exit and cylinder radius not on same straight line, when the piston during at the top dead center shape of its shape and top land cooperate, constitute a complete combustion chamber, the built -in spout that has valve, fuel sprayer or secondary combustion chamber of oblique air flue side combusion chamber, a cylinder disposes an oblique air flue side combusion chamber at least. The utility model provides a new diesel engine burning chamber structure. The problem of configuration of the valve of four -stroke -cycle opposition piston diesel engine and little cylinder diameter diesel engine enlarge the valve, improve the burning, improve and discharge, reduce fuel consumption rate is solved.
Description
Technical field：
This utility model is the combustor with regard to internal combustion engine, especially with regard to the burning of the side with oblique air flue of diesel engine
Room.
Background technology：
The combustor of existing diesel can be divided into：Open combustion chamber, semi-open type combustor and divided combustion chamber.
Shallow pot shape is made on open combustion chamber piston top, is mainly used in big-and-middle diesel engine.
Semi-open type combustor makes ω types, spherical, triangle or dimetric dell on piston top, is mainly used in medium and small
Diesel engine.
Divided combustion chamber is divided into minor air cell and precombustion chamber, is placed in cylinder head, is mainly used in medium and small-scale diesel engine.
Existing four-cycle diesel open type and semi-open type combustor have piston-top surface, cylinder wall and cylinder cover to surround and
Into.Its advantage is that fuel consumption is low, and it has the disadvantage to be limited by engine block and size.For small-bore diesel engine or
Four cycle opposed-piston formula diesel engines using open type or semi-open type combustion chambers burn as deteriorated.
Existing divided combustion chamber throttling loss of energy is more, area of dissipation is larger, residual gas is unable to emptying, fuel oil
Consumption rate is higher and starts more difficult.Due to the restriction in structure, existing divided combustion chamber is not suitable for opposed in four strokes
Apply on piston diesel engine.
The content of the invention：
The purpose of this utility model is to provide a kind of side combusion chamber with oblique air flue, solves prior art and exists not
Foot.
The technical scheme that this utility model solves the above problems is as follows：
A kind of oblique air flue side combusion chamber, it is characterised in that the side that the combustor is placed near cylinder of diesel engine piston top dead center
In other or cylinder head, there is air flue to communicate with cylinder, and the centrage of the air flue or its tangent line and cylinder at the air passage outlet
Not on the same line, when piston is in top dead-centre, the matching form of its shape and top land is closed radius, constitutes one completely
Combustor；Tiltedly air flue side combusion chamber is built-in with the spout of valve, atomizer or subsidiary combustion chamber；One cylinder at least configures one
Ge Xie air flues side combusion chamber.
This utility model provides a kind of new combustor constituted mode, breaches existing combustor by engine block
Limit.It has the following advantages：
1, be conducive to producing vortex in cylinder, air-fuel mixture and burning can be improved.
2, improve scavenging efficiency.
3, reduce restriction loss.
4, solve the valve allocation problem of four cycle opposed-piston formula diesel engines.
5, valve size can be expanded.
Description of the drawings：
Fig. 1 is a kind of structural representation of the present utility model.
1 --- oblique air flue side combusion chamber；2 --- valve；3 --- atomizer：4 --- piston.
Specific embodiment：
By the side that tiltedly air flue side combusion chamber 1 is placed near the top dead-centre of cylinder of diesel engine piston 4, there is air flue to communicate with cylinder,
And the centrage of the air flue or its tangent line at the air passage outlet are with cylinder radius not on the same line, when piston is upper dead
The matching form of its shape and top land is closed during point, constitutes a complete combustor；Tiltedly air flue side combusion chamber is built-in with spray
Oil nozzle 3 and valve 2, including inlet valve, exhaust valve, it is also possible to only a kind of valve.
Tiltedly air flue is conducive to producing vortex in cylinder, is sufficiently mixed mist of oil and air, improves burning, reduces fuel consumption
Rate, improves discharge.
One cylinder at least configures a Ge Xie air flues side combusion chamber.
Tiltedly air flue side combusion chamber can communicate or by piston top, cylinder and cylinder head with the space being made up of piston top and cylinder
The space of composition communicates.
