Abstract
The invention discloses a high-pressure oil rail of a gasoline engine. The high-pressure oil rail of the gasoline engine comprises a pipe body, an oil inlet cover arranged at one end of the pipe body and an oil inlet pipe cover. A sensor base, an oil inlet pipe base, an oil spraying base and a support are further arranged on the pipe body, and through holes communicated with the inner portion of the pipe body are arranged in the sensor base, the oil inlet pipe base and the oil spraying pipe base. The high-pressure oil rail of the gasoline engine is reasonable in structure and reliable to use and can achieve higher injection pressure, and reaches better fuel economy, dynamic property and higher emission requirement. Compared with an existing metal oil rail, the high-pressure oil rail of the gasoline engine has the advantages of being simple in structure, convenient to process, low in cost and the like.
Description
Technical field
The present invention relates to technical field of mold, particularly a kind of petrol engine high pressure oil rail.
Background technique
The engine oil rail manufacturing technology is controlled by overseas enterprise as the core technology of automobile making always, and the automobile of China's independent brand adopts the external product of import usually.Need the high usage charges of payment, virtually then added production cost, and these automobile oil bases of the rail originally all are five metals, the hardware cost of production is higher, and its body is to be made by the seamless steel pipe of standard, selects in size to suffer restraints, each parts on the body all are machined piece, structure is complicated, and the processing request ratio of precision is higher, is unfavorable for mass production; Cause the fluctuation of the oil pressure in the oily rail by pressure-relief valve release meeting; Five metals oil rail anti-vibration resistance is poorer than the oily rail of plastic cement, and at the car load Engine Block Test, plastic cement oil rail is stronger than the oily rail anti-vibration resistance of five metals, is not easy to form oil leakage phenomenon, and explosion-proof performance is higher than the oily rail of five metals.
Yet plastic cement oil rail at first will guarantee outside the performance of five metals oil rail, and plastic cement oil rail moulding and mould require highlyer, and aspect moulding, oily rail is loosed core long, and easily distortion is longly loosed core the required precision error less than 0.002mm.Guarantee to have five metals oil rail high strength, the technical standard such as plastic cement oil rail structural requirement is relatively harsher.Plastic cement oil rail environmental protection permeability resistance high, energy-conservation lightweight, raw materials consumption is few, but process engineering is complicated, higher to product requirement.
Summary of the invention
Main purpose of the present invention provides a kind of petrol engine high pressure oil rail, is intended to simplified structure, uses reliably, can realize higher jet pressure, reaches the emission request of better fuel economy, power character and Geng Gao.
The present invention proposes a kind of petrol engine high pressure oil rail, comprise a body and the feed cover that is arranged on this body one end and oil-feed body lid, also be provided with sensor holder, oil-feed base, oil spout base and support on this body, the inside of described sensor holder, oil-feed base and oil spout base all has the through hole that communicates with described body inside.
Preferably, it is one-body molded that described petrol engine high pressure oil rail adopts plastic-injection.
Preferably, be connected with a cup on the described oil spout base, this end cup one end is uncovered, the other end sealing.
Preferably, described bottom of cup has the port that communicates with through hole on the described oil spout base.
Preferably, described feed cover and oil-feed body lid ultra-sonic welded is tightly connected.
Preferably, described support is arranged on middle part and the two ends of described body.
Petrol engine high pressure oil rail of the present invention is rational in infrastructure, uses reliably, can realize higher jet pressure, reach the emission request of better fuel economy, power character and Geng Gao, compare with existing five metals oil rail, have simple in structure, easy to process, the advantage such as cost is low.
Description of drawings
Fig. 1 is the structural representation of petrol engine high pressure oil rail one angle of the present invention;
Fig. 2 is the structural representation of another angle of petrol engine high pressure oil rail of the present invention.
The realization of the object of the invention, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
Embodiment
Be described further with regard to technological scheme of the present invention below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The present invention proposes a kind of petrol engine high pressure oil rail.
See figures.1.and.2, Fig. 1 is the structural representation of petrol engine high pressure oil rail one angle of the present invention; Fig. 2 is the structural representation of another angle of petrol engine high pressure oil rail of the present invention.
In embodiments of the present invention, this petrol engine high pressure oil rail, comprise a body 1 and the feed cover 2 that is arranged on these body 1 one ends and oil-feed body lid 3, also be provided with sensor holder 7, oil-feed base 6, oil spout base 5 and support 4 on this body 1, the inside of this sensor holder 7, oil-feed base 6 and oil spout base 5 all has the through hole that communicates with body 1 inside.Exempt to establish pressure-relief valve on the body 1, this body 1 is irregular design, to reduce the caused pressure surge of pressure-relief valve.Body 1 adds plastic rubber shaping for welding, like this can be so that be not subject to the restriction of the size of standard five metals oil rail on the size Selection of body 1.Feed cover 2, support 4 and cup 8 all are the injection moulding once-throughs.
In the above-described embodiments, it is one-body molded that this petrol engine high pressure oil rail adopts plastic-injection.
Based on above-described embodiment, be connected with a cup 8 on this oil spout base 5, these end cup 8 one ends are uncovered, the other end sealing.
In the above-described embodiments, these cup 8 bottoms have the port that communicates with through hole on the oil spout base 5.
In the above-described embodiments, this feed cover 2 covers 3 ultra-sonic welded with the oil-feed body and is tightly connected.
In the above-described embodiments, this support 4 is arranged on middle part and the two ends of body 1.
Petrol engine high pressure oil rail of the present invention is rational in infrastructure, uses reliably, can realize higher jet pressure, reach the emission request of better fuel economy, power character and Geng Gao, compare with existing five metals oil rail, have simple in structure, easy to process, the advantage such as cost is low.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure transformation that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
