Abstract
The utility model relates to a pre-combustion chamber of a natural gas internal combustion engine, which belongs to the technical field of engines provided with pre-combustion chambers, and is composed of an upper body and a lower body which are installed on a cylinder head of the internal combustion engine by bolts. The upper body and the lower body are coupled through threads, and inner cavities thereof form a pre-combustion chamber, wherein, the upper body is provided with a spark plug; the lower body is provided with a through hole used for air inlet and flame spraying. The pre-combustion chamber of the utility model can raise the burning speed of mixing gas in a main combustion chamber, enlarge the range of air combustion ratio, minish the operating cycle fluctuation of the internal combustion engine, lower the exhaust temperature, improve combustion situation and power performance and raise the economic efficiency and reliability. Moreover, the utility model has simple structure, convenient disassembly, low cost, and long service life.
Description
The utility model relates to combustion engine, and the motor of precombustion chamber is particularly arranged, and particularly is a kind of rock gas internal-combustion engine precombustion chamber.
The rock gas internal-combustion engine is progressively applied in the oil field, particularly is exclusively used in the rock gas internal-combustion engine of oil field as power source, can gather materials on the spot, and the fuelled with natural gas with association in the well both reduced cost, and was very convenient again.But because existing rock gas Structure of Internal-Combustion Engine is perfect inadequately, the velocity of combustion of mixed gas is lower in its main combustion chamber, the scope of air fuel ratio is less, the fluctuation of engine operational cycle is bigger, and delivery temperature is higher, and the power character of motor and Economy are all not ideal enough.
In view of the above-mentioned shortcoming and defect part that used rock gas internal-combustion engine exists, the purpose of this utility model just is to provide a kind of rock gas internal-combustion engine precombustion chamber, overcomes above-mentioned shortcoming and defect part.
Above-mentioned purpose of the present utility model is realized by following technical proposals:
This precombustion chamber is made of upper body and lower body, is installed on the cylinder head with bolt.Upper body and lower body adopt scyewed joint, and are sealed by seal washer.After upper body and lower body attached together, its inner chamber formed precombustion chamber.Spark plug is installed on the upper body, and the lower body lower end has through hole, so that the circulation of mixed gas and the ejection of pre-burning interior flame.
This precombustion chamber inner chamber applies heat insulating coating, to keep inner chamber high temperature, is beneficial to igniting.
There is internal thread this lower end, precombustion chamber upper body, is used to install spark plug.One boss is arranged at top, upper body, and uniform 2 axial bolts holes are used for installing on cylinder head on the boss.The two seals ring recess is arranged below the boss.
Intracoelomic cavity is a toroidal under this precombustion chamber, and diameter is up big and down small.The lower body lower end is spherical, can arrange 1 to 4 through hole.
This precombustion chamber is used for the rock gas internal-combustion engine, need not change original cylinder and spark plug configuration, can improve combustion of mixed gas speed in the main combustion chamber, enlarge the scope of air fuel ratio, reduce the fluctuation of internal combustion engine circuit, reduce delivery temperature, improve combustion position and power performance, increase economic efficiency and reliability.Advantages such as in addition, this precombustion chamber also has simple in structure, and mounting or dismounting are convenient, and cost is low, and the life-span is long.
Accompanying drawing is an overall structure schematic representation of the present utility model.
In conjunction with the accompanying drawings embodiment is described below:
In the accompanying drawing, the 1st, rubber seal, the 2nd, upper body, the 3rd, intermediate seal packing ring, the 4th, lower body, the 5th, lower end seal washer, the 6th, spark plug, the 7th, cylinder head, the 8th, bolt.A is the precombustion chamber inner chamber, and B is the air inlet fire jetting hole, and C is the construction bolt hole.
The lower end of the upper body 2 of this precombustion chamber is an internal thread, and the upper end of lower body 4 is outside threads, and this internal and external threads matches, and realizes that the upper body connects with the assembling of lower body, and seal washer 3 is arranged therebetween.Top, upper body outer rim has twice rubber seal 1, and seal washer 5 is arranged at the lower body bottom.The precombustion chamber that assembles is inserted in the cylinder head from combustion engine cylinder head 7 tops, is fixed on the cylinder head by the breechblock in the C hole 8 then, spark plug 6 is installed on the upper body of precombustion chamber.
Rock gas in the cylinder and air gas mixture enter precombustion chamber inner chamber A by the B hole, are sprayed into cylinder from the B hole again by spark ignitor flame, and the mixed gas in the cylinder is lighted.The working procedure of this precombustion chamber that Here it is.On probation at 190 series natural gas internal combustion engines, reduced delivery temperature effectively, improved power character, improved economic benefit.
