Description
Technical field
The invention belongs to fuel tank field, it is related to a kind of electric heating constant temperature control fuel tank
Background technology
Diesel oil is the fuel oil that Diesel engine is used, and the label of diesel oil is divided into 0 in China#、-10#、-20#、
-35#With -50#, wherein 0#Diesel-fuel price is minimum, engine combustion power maximum.With 1 liter 0#Diesel oil ratio uses 1
Rise -35#Diesel oil will save 2 yuans.
When oil temperature is less than 0 DEG C, 0#Diesel oil easily analyses wax crystallization jelly, viscosity increase, mobility, atomizing effect
All it is deteriorated, incomplete combustion, oil consumption becomes big, and the amount of smoke that exhaust emissions occurs also increases, and in diesel oil
The solid paraffin of precipitation can cause the positions such as asphalt channel, filter screen to block, and fuel oil supply is reduced and even stopped,
Cause engine misses.When oil temperature is higher than 0 DEG C, 0#Diesel oil is transparency liquid, is adapted to 0#The temperature that diesel oil is used
Scope is 4 DEG C~39 DEG C.In northern China winter season, many drivers are in order to be able to be continuing with 0#Diesel oil, meeting
Fuel tank is toasted using motor exhaust, or the cooling water of engine is accessed into fuel tank to 0 by pipeline#Diesel oil enters
Row hot water circulation heated.The temperature of vehicle exhaust is up to thousands of degrees Celsius, and the water temperature in engine water tank also exists
90 DEG C or so, the above method can not all make the temperature control of diesel oil 4 DEG C -39 DEG C this in the range of.And diesel oil
It is again liquid that heat conduction is exceedingly fast, with the 0 of tail gas heating#Diesel oil oil temperature has been seethed with excitement sometimes, uses hot water circuit
The oil temperature of heating can also reach more than 80 DEG C.
Diesel oil is short chain organic matter, and when oil temperature is more than 39 DEG C, its short chain molecule will be affected, in oil
Molecular structure will change, most obvious is exactly that molecule distance is increased, movement velocity quickening.Too
Ground heating can make 0#The vapo(u)rability increase of diesel oil, makes a part of diesel oil be evaporated from fuel tank and (meets naked light easily to occur
Fire) because diesel oil evaporation rate is too fast, accumulation massive diesel-fuel in engine chamber can be made, cause to start
Machine job insecurity.Meanwhile, vapo(u)rability is strong, i.e., diesel oil distillate lightens, and viscosity is necessarily small, if viscosity mistake
Small, though atomization is good, jet angle is big and near, prevents oil plant from being thoroughly mixed with the oxygen in air, while
Lubricity to parts such as atomizers is deteriorated, and can not only increase injection pump abrasion, and reduces atomization quality,
Deteriorate combustion process.This phenomenon influences more serious for configuring state's IV vehicles of EFI oil plant.
The defective work that the tail gas discharged with vehicle is heated to fuel tank is except being the oil temperature it cannot be guaranteed that appropriate
Result in outward outside many adverse consequences, also there is a problem that influenceing engine work, i.e. engine
Efficient cause exhaust emissions does not reduce freely；Heating is circulated to fuel tank with the hot water in vehicle cooling water case,
The scientific design for changing engine cool water circulation is there is, the radiating effect of engine is have impact on, and
Once the cooling water water pipe being altered ruptures leak because of quality problems, engine can be caused because of dehydration high temperature
And scrap.
The content of the invention
It is an object of the invention to solve the technology hardly possible that can not control oil temperature that above-mentioned existing heated fuel oil case is present
Topic, so as to provide a kind of electric heating constant temperature control fuel tank, can make oil temperature in diesel engine fuel-firing case all the time
It is maintained within the scope of 4 DEG C~39 DEG C.
The technical solution adopted by the present invention：A kind of electric heating constant temperature controls fuel tank, including casing and hot room,
Be provided with above casing fuel filler neck, oil-out (being connected with engine oil-suction pipe), oil return opening (and engine return
Oil pipe is connected), bottom half is provided with sewage draining exit.Hot room is in box house.Used by hot room of the present invention
Generator of the power supply from motor vehicles or engineering machinery.Hot room can be with the guarantee fuel tank of temperature in a balanced way
0#The oil temperature of diesel oil is all the time within the scope of 4 DEG C~39 DEG C.Fuel feed hole is provided with hot room side panel.
The inside of hot room is provided with electric heater, plays thawing analysis wax crystallization jelly 0#Diesel oil is transparency liquid
Effect.Temperature probe is installed in hot room, by the oil temperature data of hot room to casing outside digital display temperature-control
Instrument is transmitted, and with the connection of the electrical equipment such as single-phase air switch, solid-state relay, constitute oil temperature of the invention
Automatic controlled box.The effect for setting control box is oil temperature in automatic heating room, or allows vehicle drivers and engineering
The operator of machinery controls the oil temperature in hot room manually, so as to ensure the oil plant entered in engine oil-suction pipe
Temperature is within 4 DEG C~39 DEG C critical fields.
Engine oil-suction pipe oil inlet of the invention is arranged on the ring-type electric heater middle part in hot room, oil return
Pipe is arranged in hot room, it is therefore an objective to make full use of oil return waste heat, mitigates the live load of electric heater.
The positive beneficial effect that the present invention has：The diesel engine under severe cold environment is ensure that in the method for science
Motor-car and engineering machinery are continuing with 0#Diesel oil.Can not only reduce the operation of motor vehicles and engineering machinery into
This, while eliminating other melts analysis wax crystallization 0#The negative effect that diesel oil is brought by the method for transparency liquid,
Made contributions for country saves petroleum resources.
