Abstract

The utility model relates to a fuel oil oil-pressure guide rail assembly for an engine capable of directly injecting ethanol fuel by a manifold. four branch pipes and two guide rail mounting brackets are uniformly distributed at and are communicated with the axial side of a tubular oil-pressure guide rail; an oil inlet connector of the oil-pressure guide rail is connected with a connector pipe; the cross section of the oil-pressure guide rail is squared; and the connector pipe on the oil inlet connector of the oil-pressure guide rail is provided with a rapid-inserting connector. The oil-pressure guide rail adopts the squared section so as to effectively reduce the vibration frequency and meet the design indexes; the assembling requirements are met by optimizing the mounting brackets of the oil rail; and meanwhile, the scheme of the rapid-inserting connector is adopted, so that the assembling efficiency is improved.

Description

Be used for the fuel oil oil pressure rail assembly that menifold directly sprays the alcohol fuel motor
Technical field
The utility model belongs to technical field of internal combustion engines, is specifically related to the fuel oil oil pressure rail assembly that a kind of menifold directly sprays the alcohol fuel motor.
Background technique
Fuel oil oil pressure rail assembly is that menifold directly sprays the vitals in the alcohol fuel engine system realizing the conveying of alcohol fuel motor fuel and prevent to have played very big effect in the fueling injection pressure fluctuation.The oily rail of existing petrolic fuel oil oil pressure rail assembly adopts the rectangular cross-section, and joint adopts the mode of rubber pipe clamping.Existing petrolic fuel oil oil pressure rail assembly can't satisfy the matching requirements of ethanol engine; The vibration frequency of fuel oil oil pressure guide rail far surpasses design objective simultaneously, can't meet design requirement; Filler opening adopts the mode of rubber pipe clamping, and efficiency of assembling is lower.
The model utility content
Carry and prevent the fueling injection pressure fluctuation in order to solve the alcohol fuel motor fuel; The utility model provides a kind of and can mate the oil pressure rail assembly that menifold directly sprays the alcohol fuel motor through the improvement to existing petrolic fuel oil oil pressure rail assembly.
The technical solution that realizes above-mentioned purpose is following:
Be used for the fuel oil oil pressure rail assembly that menifold directly sprays the alcohol fuel motor; The oil pressure guide rail that comprises tubulose; An axial side of oil pressure guide rail is uniformly distributed with and is being communicated with four arms and two guide rail mounting brackets, and the oil-feed connection mouth place of oil pressure guide rail is connecting adaptor tube, and improvement is:
The cross section of said oil pressure guide rail is a square;
The adaptor tube at the oil-feed connection mouth place of said oil pressure guide rail is provided with quick inserting joint.
The oil pressure guide rail of the utility model adopts foursquare cross section, reduces vibration frequency effectively, satisfies design objective; Mounting bracket through optimizing oily rail satisfies matching requirements; Adopt the scheme of push-in joint simultaneously, improve efficiency of assembling.

Fig. 3 is the A-A sectional view of Fig. 1.
Sequence number among the last figure: cylinder cap 1, guide rail mounting bracket 2, oil pressure guide rail 3, oil sprayer 4, cushion block 5, quick inserting joint 6, adaptor tube 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2; Be used for the oil pressure guide rail 3 that fuel oil oil pressure rail assembly that menifold directly sprays the alcohol fuel motor comprises tubulose; An axial side of oil pressure guide rail 3 is uniformly distributed with and is being communicated with four arms and two guide rail mounting brackets 2, and the cross section of oil pressure guide rail is a square; The oil-feed connection mouth place of oil pressure guide rail is connecting adaptor tube 7, and quick inserting joint 6 is installed on the adaptor tube 7.
Referring to Fig. 3, when installing and using, oil pressure guide rail 3 is installed in through two guide rail mounting brackets 2 on the cylinder cap 1 of motor, two guide rail mounting brackets 2 respectively with cylinder cap 1 on cushion block 5 be fixedly connected; Article four, arm is communicated with the oil sprayer 4 of motor respectively; The oil-feed connection mouth links to each other with the low pressure oil circuit through quick inserting joint 6; Fuel is transported to the low pressure oil circuit through the oil transfer pump in the fuel tank; Arrive 3 storages of oil pressure guide rail then, the fuel pressure of oil pressure guide rail 3 carries out oil pressure control through the pressure regulator valve on the oil transfer pump and guarantees that oily rail pressure is 4.2bar.
The utility model can satisfy alcohol fuel engine fuel supply system and be total to the fuel storage of rail oil circuit and the requirement of working pressure and corrosion resistance.
