Abstract
The utility model relates to a side combustion chamber of a diesel engine, which is characterized in that the combustion chamber is arranged at the side near the dead center on a diesel engine cylinder piston. The combustion chamber is also communicated with the space which is formed by a piston top and a cylinder wall. When the piston reaches the dead center, the shape of the piston corresponds to that of the groove which is on the top of the piston, and a whole combustion chamber is formed. The inner part of the combustion chamber is provided with an air valve, an oil nozzle and airway or spout of an auxiliary combustion chamber. The utility model provides a new formation way of a novel combustion chamber and solves the problem that the prior combustion chamber is limited by the structure of the diesel engine.
Description
Technical field:
The utility model is the firing chamber about internal-combustion engine, particularly a kind of side combusion chamber about diesel engine.
Background technique:
The firing chamber of existing diesel can be divided into: open combustion chamber, semi-open type firing chamber and divided combustion chamber.
Make shallow pot shape on the open combustion chamber piston head, be mainly used in large and medium-sized diesel engine.
ω type, sphere, triangle or dimetric dell are made in the semi-open type firing chamber on piston head, be mainly used in medium and small diesel engine.
Divided combustion chamber is divided into vortex chamber and precombustion chamber, places in the cylinder head, is mainly used in medium and small diesel engine.
Existing open type and semi-open type firing chamber are all surrounded by piston-top surface, cylinder wall top and cylinder head plane and form.Its advantage is that fuel consumption rate is low, and its shortcoming is the restriction that is subjected to diesel engine structure and size.Worsen as adopting open type or semi-open type firing chamber, burn to understand through extra small diesel engine or little cylinder diameter four-stroke opposed piston diesel engine for cylinder, fuel consumption rate can raise.
Existing divided combustion chamber is because the throttling loss of energy is more, heat diffusion area is big, residual gas can not drain, and fuel consumption rate is higher, and starts difficulty.Because structural restriction, existing divided combustion chamber can't be used on the four-stroke opposed piston diesel engine of cylinder head not having.
Summary of the invention:
The purpose of this utility model is to provide a kind of side combusion chamber, solves the deficiency that prior art exists.
The technological scheme that the utility model addresses the above problem is as follows:
A kind of side combusion chamber is characterized in that this firing chamber places by near the side of cylinder of diesel engine piston upper dead center, and communicates with the space that is made of piston head and cylinder wall.When piston during at upper dead center, its shape and piston head groove shapes match, and constitute a complete firing chamber.The side combusion chamber is built-in with the air flue or the spout of valve, oil nozzle or subsidiary combustion chamber.The shape of side combusion chamber can be eddy current shape, ω shape, basin shape.A cylinder disposes a side combusion chamber at least.
The utility model provides a kind of new firing chamber constituted mode, has broken through the restriction that existing firing chamber is subjected to the diesel engine structure.It has following advantage:
1, can solve the valve allocation problem of little cylinder diameter four-stroke opposed piston diesel engine.
2, make full use of the valve opening space as the firing chamber.Compact structure, heat diffusion area is little.
3, help fully ventilation in the cylinder.
4, help the abundant mixing of mist of oil and air.
5, restriction loss is little.
6, improve engine fuel economy, reduce fuel consumption rate.
7, easily start.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
1---the side combusion chamber; 2---valve; 3---oil nozzle; 4---piston.
Embodiment:
Side combusion chamber 1 places by near the side of cylinder of diesel engine piston 4 upper dead centers, and communicates with the space that piston head and cylinder wall constitute by air flue.When piston during at upper dead center the shape of its shape and piston head groove match and constitute a complete firing chamber.The side combusion chamber is equipped with valve 2, can be exhaust, two kinds of valves of air inlet, also can have only a kind of valve in a side combusion chamber.
This side combusion chamber also is equipped with oil nozzle 3.
This side combusion chamber is an eddy current shape.The air swirl that produces during the diesel engine compression stroke helps the abundant mixing of mist of oil and air, can reduce fuel consumption rate.
Because side combusion chamber's air flue flow area is bigger, does not have tangible restriction loss.
A cylinder disposes a side combusion chamber at least.
Claims (4)
1. side combusion chamber, it is characterized in that this firing chamber places by near the cylinder of diesel engine piston upper dead center the side, and communicate, when piston during at upper dead center with the space that constitutes by piston head and cylinder wall, its shape and piston head groove shapes match, and constitute a complete firing chamber; The side combusion chamber is built-in with valve.
2. side combusion chamber according to claim 1 is characterized in that the side combusion chamber is built-in with the air flue or the spout of oil nozzle or subsidiary combustion chamber.
3. side combusion chamber according to claim 1 is characterized in that it is shaped as eddy current shape, ω shape or basin shape.
4. side combusion chamber according to claim 1 is characterized in that a cylinder disposes a side combusion chamber at least.
