Abstract
The invention discloses a centrally installed structure of a diesel engine fuel filter. The technical scheme is as follows: an engine oil cooler is fixedly arranged at the side of a diesel engine cylinder body, and an engine oil cooler cover is cast with a flange surface for installing the fuel filter; the fuel filter with a mounting flange is fixedly arranged on an outer cover of the engine oil cooler. An oil return pipe assembly of the fuel filter and an oil inlet pipe assembly of the fuel filter are respectively connected with an injection pump. The injection pump is positioned at the front end of the diesel engine, and one end of an injection pump oil inlet pipe is connected with the fuel filter; the other end of the injection pump oil inlet pipe is connected with the injection pump. With the structure, the control flexible axle of a vehicle is conveniently arranged, and meanwhile, the length of a fuel pipeline is shortened by about one third. Because the fuel filter is directly arranged on the engine oil cooler cover without a cantilever beam, the contact areas of two joint surfaces are large, the vibration amplitude is small, the shaking problem of the fuel filter is significantly improved, and the centrally installed structure is suitable for assembly systems of a plurality of diesel engine fuel filters.
Description
Technical field
The invention belongs to engine components, be specifically related to a kind of assembly structure of diesel engine fuel-firing filter cleaner.
Background technique
In diesel engine parts trim designs, fuel filter is all arranged in rear end, cylinder head side substantially at present, or on the position that motor is higher relatively such as suction tude upside.But while mating on the little tonnage car of narrow body, installation biased outward and the position of fuel filter are higher, cause the operation flexible axle difficult arrangement of gearbox, and flexible axle bracing wire often there will be the problem of interference.It is also relatively long that fuel filter cloth sets high fuel pipe, and longer pipeline is due to bad fixing, and the vibration of engine long time will there will be cracking hidden danger.Therefore best assembling scheme is that motor middle part is shifted to in the position of fuel filter, and to the convergence of body inner side, is directly fixed on machine oil cooler and covers.The present invention proposes the layout that a kind of fuel filter is new for this reason, can solve the problems such as narrow body car operation flexible axle difficult arrangement.
Summary of the invention
The object of the invention is, provide a kind of diesel engine fuel-firing filter cleaner mid-structure, to meet the needs of multiple crawl space diesel engine car load configuration.
For realizing the technological scheme that this object takes, be: machine oil cooler is fixed on the side of diesel engine cylinder body with the fuel filter of mounting flange, to be fixed on the outer of machine oil cooler and to cover.The return tube assembly of fuel filter, the oil inlet pipe assembly of fuel filter are connected with Injection Pump respectively.Injection Pump is positioned at the front end of diesel engine, and Injection Pump oil inlet pipe one end is connected with fuel filter; The other end is connected with Injection Pump.
Because diesel engine overall width is very important to arrangement, this plan of establishment has been located at fuel filter at the middle part of diesel engine, the mid-related a plurality of parts of fuel filter must be re-started to optimum organization for this reason.Discharging valve support, tommy bar and the joint chair etc. that comprise former this position are optimized design, abdicate and arrange fuel filter space.On cooler for engine oil cover, cast out the flanged surface that fuel filter is installed, to be fixed on intercooler with mounting flange filter cleaner and cover, the parts such as the return tube assembly relevant with filter cleaner, oil inlet pipe assembly and Injection Pump oil inlet pipe assembly will be connected on Injection Pump.
Feature of the present invention and beneficial effect are that (1) this structure is abdicated the space of upper end after motor, facilitates car load operation flexible axle to arrange; Make fuel pipe shorten length approximately 1/3 simultaneously, avoided the engine long time to run up, vibration causes the fault of fuel pipe cracking; (2) because the direct fitting machine oil cooler of fuel filter cover, without overhang, two junction area of contact is large, Oscillation Amplitude is little, also make fuel filter jitter problem be improved significantly; (3) this layout has effectively promoted complete machine appearance quality, and is suitable for the assembly system of multiple diesel engine fuel-firing filter cleaner.
Accompanying drawing explanation
Shown in accompanying drawing be stereochemical structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, structure of the present invention is further described.Diesel engine fuel-firing filter cleaner middle-containing structure, comprising: diesel engine cylinder body, machine oil cooler, filter cleaner return tube assembly, fuel filter, filter cleaner oil inlet pipe assembly, Injection Pump oil inlet pipe and Injection Pump etc.Its structure is: machine oil cooler 2 is fixed on the side of diesel engine cylinder body 1, casts out the flanged surface that fuel filter is installed on cooler for engine oil cover, is fixed on the outer of machine oil cooler covers with the fuel filter 4 of mounting flange.The return tube assembly 3 of fuel filter, the oil inlet pipe assembly 5 of fuel filter are connected with Injection Pump 7 respectively, and Injection Pump is positioned at the front end of diesel engine.Injection Pump oil inlet pipe 6 one end are connected with fuel filter; The other end is connected with Injection Pump.
The light truck of the CY4100 serial diesel engine of take coupling 1.5-3 ton is example, installation setting because of various parts, fuel filter can only be arranged in rear end, cylinder block right side or on the higher position of the relative motor of suction tude, with car load operation flexible axle bracing wire severe interference, and cannot entrucking.And the proposition of this structure makes the mid-connection and reasonable arrangement of fuel filter, compactness, taking up room diminishes relatively, can adapt to the demand of any tonnage car load, has practicability widely.
Claims (1)
1. diesel engine fuel-firing filter cleaner middle-containing structure, comprise: diesel engine cylinder body, machine oil cooler, filter cleaner return tube assembly, fuel filter, filter cleaner oil inlet pipe assembly, Injection Pump oil inlet pipe and Injection Pump, it is characterized in that: machine oil cooler (2) is fixed on the side of diesel engine cylinder body (1), on machine oil cooler enclosing cover, cast out the flanged surface that fuel filter is installed, with the fuel filter (4) of mounting flange, being fixed on the outer of machine oil cooler covers, the return tube assembly (3) of fuel filter, the oil inlet pipe assembly (5) of fuel filter is connected with Injection Pump (7) respectively, Injection Pump is positioned at the front end of diesel engine, Injection Pump oil inlet pipe (6) one end is connected with fuel filter, the other end is connected with Injection Pump.
