Description
Technical field
The utility model relates to a kind of diesel engine, relates in particular to the device of the integrated Coolers of a kind of diesel engine, fuel filter, belongs to diesel engine fuel feeding and cooling system technical field.
Background technique
Diesel engine will keep normal oil temperature at work: the one, and particularly the temperature of crankshaft bearing is too high in order not make the friction parts, and intensity reduces, the wearing and tearing aggravation; The 2nd, make the machine oil viscosity suitable, good mobility is arranged, cooled off reliably and lubricated to guarantee friction surface; The 3rd, can reduce the speed of machine oil oxidation at high temperature, to prolong the working life of machine oil.Therefore machine oil will cool off, and needs cooler.Equally, diesel engine will keep normal fuel oil temperature at work, otherwise fuel oil at high temperature can produce gasification and cavity phenomenon, influences power character.Therefore fuel oil also will cool off, and also needs cooler.
Diesel engine no matter is machine oil or fuel oil, all need cleans that its reason is self-evident, so should be furnished with oil filter and fuel filter.
On conventional diesel engine, above-described cooler and filter cleaner are separated types, and its shortcoming is that mechanism is loose, and quantity is many, and it is big to take up room.Someone has adopted the structure that oil filter and machine oil cooler are combined, and this compares with traditional separated type, compact structure with take up room little.Like Chinese patent notification number: 102011623A; The day for announcing: on April 13rd, 2011; The model utility title: " a kind of engine motor oil cooler and oil filter composite set ", it becomes one oil filter and machine oil cooler, is installed in together on the machine oil cooler assembly shell.Though existing technology through integrated, has reduced the volume of oil filter and machine oil cooler,, strict day by day in the face of automobile emission regulation, also in the constantly requirement of upgrading, then there is following deficiency in existing technology to diesel oil Electrocontrolled high-pressure common rail spraying technique:
Recent years, the Electrocontrolled high-pressure common rail spraying technique is with its faster system response, and the precision height progressively becomes diesel engine configuration main flow.It is very thin that the Electrocontrolled high-pressure common rail spraying technique gets diesel oil atomization, lets burning not only fully but also not improve FT, and hazardous emission is few, satisfies automobile emission regulation and is strict with day by day.But it is traditional four, five times that the Electrocontrolled high-pressure common rail spraying technique requires system pressure, from being lower than 200MPa, rises to 250MPa, higher to 300MPa.Therefore, under the effect of high pressure, system temperature raises, and needs to increase cooling system control temperature, increases pipeline accordingly and connects, and it is complicated more that crowded originally engine nacelle is arranged.And the motor outer space is limited, and is very big to the limitation of newly-increased line arrangement, if set up reluctantly; Then cause interference, leakage and installation and inconvenient maintenance easily, therefore, though the oil filter of existing technology and machine oil cooler integrated one; But with still three parts independently separately of fuel filter and Fuel Oil Cooler; Two overlap laying of cooling pipes in addition, and number of devices is many, and it is big to take up room; Make and learn on the existing diesel, existing does not have the space to set up the deficiency of the cooling infrastructure of Electrocontrolled high-pressure common rail spraying technique again.
Summary of the invention
The purpose of the utility model is to overcome existing fuel filter and Fuel Oil Cooler and cooler thereof etc., and number of devices is many, and it is big to take up room; Make on existing diesel; Do not have the space to set up the deficiency of the cooling infrastructure of Electrocontrolled high-pressure common rail spraying technique again, a kind of integrated morphology is provided, number of devices is few; It is little to take up room, and can set up the integrated Coolers of a kind of diesel engine of the cooling infrastructure of Electrocontrolled high-pressure common rail spraying technique, the device of fuel filter by slot milling.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is: the device of the integrated Coolers of a kind of diesel engine, fuel filter comprises assembly shell, machine oil cooler, oil filter, fuel filter, Fuel Oil Cooler, cooling liquid inlet, cooling pipe, cooling liquid outlet, machine oil import, engine oil pipeline, machine oil outlet, fuel filler, fuel line, fuel outlet, said engine oil pipeline; The slave oil inlet gets into assembly shell, successively connects machine oil cooler and oil filter, passes from assembly shell again; End to machine oil outlet, said fuel line gets into assembly shell from fuel filler; Successively connect Fuel Oil Cooler and fuel filter, spread out of from assembly shell again, end to fuel outlet; In the described assembly shell, the top in the described assembly shell is pacified set machine oil cooler and Fuel Oil Cooler side by side; Below machine oil cooler, peace set oil filter is below Fuel Oil Cooler; Peace set fuel filter, described cooling pipe gets into assembly shell from cooling liquid inlet; Be divided into two the tunnel then, connect machine oil cooler and Fuel Oil Cooler respectively after, remerge Cheng Yilu; Spread out of from assembly shell, end to cooling liquid outlet.Described cooling pipe gets into assembly shell from cooling liquid inlet, is divided into two the tunnel then, connects machine oil cooler and Fuel Oil Cooler respectively, passes from assembly shell respectively, remerges Cheng Yilu, ends to cooling liquid outlet.
Described oil filter is installed on the shell of assembly shell.
Described fuel filter is installed on the shell of assembly shell.
Compared with prior art, the beneficial effect of the utility model is: 1. adopt in the assembly shell, concentrate peace set machine oil cooler, oil filter, fuel filter, Fuel Oil Cooler; Make that the interior device of installing of engine compartment is few, and each device is pacified admittedly the pipeline weak point in the ordered set in assembly shell; It is little to take up room; Not only reduce the risk of leaking, improve system reliability, can also set up the cooling infrastructure of Electrocontrolled high-pressure common rail spraying technique by slot milling.2. adopt cooling liquid one tunnel to get into assembly shell, divide two the tunnel to connect machine oil cooler and Fuel Oil Cooler respectively again, with a cover external refrigeration pipeline, practice thrift the pipeline cost more than 30% less.3. save the space more than 50% than existing technology, can satisfy the space requirement of the cooling infrastructure of setting up the Electrocontrolled high-pressure common rail spraying technique fully.
