Abstract
A split fixing device of a fuel slideway and an injection system includes a split connector group, wherein the connector group includes at least one connector unit, and at least one passage opening penetrates through the surface of each connector and is arranged along the middle part of the connector; a first injector opening is communicated with the passage opening; and a first injector mounting hole is formed at the first injector opening and is suitable for mounting the injectors of different specifications. The fixing and mounting device is used for increasing other fuel slideways or the injection systems without changing the air inlet passage of the existing air inlet manifold, so that the existing engine air inflow is not changed, and the fuel consumption of the existing vehicle is ensured without influencing the performance of the engine. The split fixing device saves more materials and reduces more cost, and has wide application range.
Description
Technical field
The utility model relates to the fixing device of a kind of split type fuel rail and ejecting system.
Background technique
Because international petroleum rises steadily, international and domestic many-side is sought alternative energy source, and automobile-used double fuel and many fuel injection systems begin to be accepted by people, and also trend is ripe towards market under government promotes and supports.How solve on the fixation problem of ejecting system and guide rail, also begun various exploration and practices.The fixing device that occurs on the market is the integral type design apparatus; Both waste material had increased cost, when producing interference owing to having increased intake manifold length and to other parts of motor; Increased engine intake manifold passway volume; Thereby can change the air input of engine by air parameter, influence engine performance, and install in vehicle and to have narrow limitation.
The model utility content
The utility model provides the fixing device of a kind of split type fuel rail and ejecting system, and project organization is the structure of divided connector group cleverly, makes the problem of existence in the market to solve.
The utility model is to realize like this; The fixing device of a kind of split type fuel rail and ejecting system; This device comprises the connector group that split is provided with, and the connector group comprises at least one connector unit, and each connector unit surface connects the passway of offering; Said passway is at least one, and the passway is provided with along the connector unit middle part; First eductor ports links to each other with the passway; The place is set with the passage device in the connector unit passway, and the passage device the other end links to each other with intake manifold; Said connector unit top is provided with mounting end, and said mounting end outer surface connects and is provided with the second sparger mounting hole that communicates with second eductor ports; The said second sparger mounting hole is at least one, and evenly is provided with along mounting end according to the intake manifold situation.
Connector unit and engine body are for closely to be connected; Said passage device and connector unit are for detachably closely to be connected; Said passage device thickness volume is identical with the passway vessel volume on connector unit surface; Said passage device matches with the interior tube shape of intake manifold, and is closely to connect.
Said first eductor ports is provided with the first sparger mounting hole, and the said first sparger mounting hole is consistent with the medial axis of first eductor ports, and the first sparger mounting hole can adapt to installation different model sparger.
Said connector unit also comprises fixed hole, in order to connector unit is fixedly connected with engine body.
The invention has the beneficial effects as follows:
1, Patent Office of the People's Republic of China's granted patent number is: CN201020287015.8, and notice of authorization day is the fixing device that the utility model patent on April 27th, 2011 discloses a kind of automotive fuel nozzle ejection, its structure is comparatively simple; But because the design of integral type, material thickness has been controlled not, has increased flange thickness; Cause interference easily to other parts of motor; Can increase engine intake manifold length after increasing erecting device, promptly increase the intake manifold admission space, can change the motor amount of carrying out; And influence the engine parameter performance, influence former car performance parameter and influence fuel consumption;
2, the utility model; Utilize split type setting, solved behind the increase erecting device and can interfere other parts of motor, promptly can to divided connector according to motor environmental requirement adjust design; Economical with materials also can directly be installed multiple ejecting system and track-type facilities simultaneously;
3, the utility model utilizes split-type design, and the passage device is set; Changed intake manifold length; The utility model is long-pending suitable with increase device partial-air admission manifold volume with the passage body, thereby does not change the intake manifold volume, and it is dense rare not change former car air inflow and mixed gas; Stop to change intake manifold length and volume engine performance is exerted an influence, reduce cost of material and fuel consumption simultaneously.
