Abstract
The utility model discloses a high-pressure oil rail of a gasoline engine. The high-pressure oil rail comprises a tube body, an oil inlet cover and an oil inlet tube body cover, wherein the oil inlet cover and the oil inlet tube body cover are arranged at one end of the tube body. A sensor base, an oil inlet tube base, oil injection tube bases and supports are further arranged on the tube body. Through holes are formed in the sensor base, the oil inlet tube base and the oil injection tube bases and communicated with the inside of the tube body. The high-pressure oil rail of the gasoline engine is reasonable in structure, reliable in using and capable of achieving higher injection pressure and reaching better fuel economy, power performance and higher requirements for emission. Compared with an existing hardware oil rail, the high-pressure oil rail of the gasoline engine has the advantages of being simple in structure, convenient to machine, low in cost and the like.
Description
Technical field
The utility model relates to technical field of mold, particularly a kind of petrol engine high pressure oil rail.
Background technique
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, then added production cost virtually, and these automotive oil bases of the rail originally all are five metals, the hardware cost of production is than higher, and its body is to be made by the seamless steel pipe of standard, suffers restraints on size is selected for use, 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 than the oily rail height 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 than higher, and aspect moulding, oily rail is loosed core long, and easy deformation is longly loosed core the required precision error less than 0.002mm.Guarantee to have five metals oil rail high strength, plastic cement oil rail structural requirement is technical standard such as harshness relatively.Plastic cement oil rail environmental protection permeability resistance height, energy-conservation in light weight, raw materials consumption is few, but process engineering complexity, higher to product requirement.
The model utility content
Main purpose of the present utility model 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 utility model proposes a kind of petrol engine high pressure oil rail, comprise a body and 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, described petrol engine high pressure oil rail adopts the moulding of plastic cement integrated through injection molding.
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 the middle part and the two ends of described body.
Petrol engine high pressure oil rail of the present utility model 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, have simple in structure with existing five metals oil rail, easy to process, advantage such as cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model petrol engine high pressure oil rail one angle;
Fig. 2 is the structural representation of another angle of the utility model petrol engine high pressure oil rail.
The realization of the utility model purpose, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model proposes a kind of petrol engine high pressure oil rail.
See figures.1.and.2, Fig. 1 is the structural representation of the utility model petrol engine high pressure oil rail one angle; Fig. 2 is the structural representation of another angle of the utility model petrol engine high pressure oil rail.
In the utility model embodiment, this petrol engine high pressure oil rail, comprise a body 1 and 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 is for welding adds plastic rubber shaping, can make the restriction of the size that is not subjected to standard five metals oil rail on the size Selection of body 1 like this.Feed cover 2, support 4 and cup 8 all are the injection moulding once-throughs.
In the above-described embodiments, this petrol engine high pressure oil rail adopts the moulding of plastic cement integrated through injection molding.
Based on the foregoing description, 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 the middle part and the two ends of body 1.
Petrol engine high pressure oil rail of the present utility model 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, have simple in structure with existing five metals oil rail, easy to process, advantage such as cost is low.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; 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 utility model.
