Description
(1) technical field
The present invention relates to a kind of low-pressure oil supply system for diesel vehicle.
(2) background technique
As everyone knows, the diesel vehicle that travels winter because temperature is low, often takes place that diesel oil is frozen the phenomenon of condensing in fuel tank and the transport pipe, make oil circuit hang cured, stop up, can't give the motor normal fuel injection, influence vehicle driving.Especially sail the cold north from warm south into or sail the vehicle of the use low grade diesel oil in mountain area into, because difference variation is very big, diesel oil is very easy to be condensed.If run into this situation in high and cold outlying mountain area, vehicle can not be exercised, and people and vehicle commander are in the environment of low temperature the time, and personnel's frostbite takes place easily, even entail dangers to is to driver and conductor's life safety.Often can see the phenomenon (use No. 0 diesel oil, this phenomenon more general) of driver with naked light barbecue diesel-oil vehicle fuel tank, oil pipe winter in the north, this not only impairs vehicle, and the danger of initiation fire is arranged.If this situation occurs on the busy highway, will cause the obstruction of traffic.
For addressing this problem.The hot gas that patent CN02244181.6 discharges with the diesel-oil vehicle engine cylinder carries out heat exchange by being located at the pipeline in the fuel tank with diesel oil, and diesel oil can not condensed in the winter of cold.This method has such problem: 1. at cold in the winter time night, when the driver and conductor was stopped rest, to stall, do not have thermal source this moment, and diesel oil still can condense, and causes second day car to start.2. use the engine cylinder discharge tail gas to destroy the effect of Vehicular silencer, the noise of car is increased, and make fuel tank vibrations aggravation, influenced the original performance of car.3. winter, the easiest transport pipe position of stopping up of condensing did not have antifreeze facility.
In addition, also have the storage battery of first wife on the human car to make the energy, the fuel tank by electric heating wire heating diesel-oil vehicle thaws oily temperature rise.The problem of doing like this is, because fuel tank is bulky, even the diesel oil of whole fuel tank is heated up by a small margin, also needs long time or a large amount of electric energy, and, because the fuel tank volume is big, also be not easy insulation.In fact, even the diesel oil that the electric power of first wife's storage battery all is used for fuel tank on the car is heated, make the oil temperature be elevated to 20 ℃ from-10 ℃, electric power badly influences the original electric property of vehicle with approach exhaustion in 2 hours.
(3) summary of the invention
For overcome in the prior art diesel-oil vehicle stop winter when spending the night or during driving diesel oil condense, the insulation of diesel oil, heat riser power consumption are big, temperature rise time length, poor stability, have a strong impact on the deficiency of the original performance of vehicle, the invention provides that a kind of power consumption is little, temperature rise time weak point, high insulating effect, Security are good, can not influence the insulation of the original performance of vehicle, the low-pressure oil supply system for diesel vehicle of intensification diesel oil.
Technological scheme of the present invention is:
A kind of low-pressure oil supply system for diesel vehicle, comprise the diesel-oil vehicle fuel tank, the transport pipe that is communicated with the diesel-oil vehicle fuel tank, the transport pipe place is provided with oil pump, described diesel-oil vehicle fuel tank is connected with a small-sized fuel reserve tank, the delivery outlet of small-sized fuel reserve tank connects transport pipe, and described small-sized fuel reserve tank is coated with the electric heating film that is electrically connected with power supply with transport pipe.
Described electric heating film is a polyester double-sided insulation electric heating film.
Be provided with hot channel in the described diesel-oil vehicle fuel tank, described hot channel one end connects the heating system on the car, and the other end leads to atmosphere.
Be provided with temperature sensor probe in the described small-sized fuel reserve tank, and be its configuration automatic temperature control circuit.The output signal of temperature transducer is sent to automatic temperature control circuit, the switching of automatic temperature control circuit control electric heating film.
The power supply of electric heating film is a storage battery, and described storage battery is provided with automatic charging control circuit.
Described electric heating film is coated with thermal insulating material.
The volume of small-sized fuel reserve tank is the 0.3-30 liter.
The distance of small-sized fuel reserve tank and diesel-oil vehicle fuel tank is the 0-20 centimetre.
Because the volume of small-sized fuel reserve tank and transport pipe is all very little, heating easily, also insulation easily is apparent, make oily temperature in the small-sized fuel reserve tank remain on 15 ℃ and remain on 15 ℃ than the oily temperature that makes whole fuel tank and will save a large amount of electric power, promptly make diesel oil constant temperature in the small-sized fuel reserve tank with a spot of electric power.No matter be in parking or in driving, always the diesel fuel temperature in the small-sized fuel reserve tank remains on the incoagulable temperature spots by temperature automatically controlled and heater circuit.After car being started travel with the diesel oil in the small-sized fuel reserve tank, at this moment motor produce warm braw (the heating installation air channel of promptly leading to operator cabin), taking out a part sends in the hot channel that is arranged in the fuel tank, carry out the temperature that heat exchange promotes whole diesel oil in the fuel tank with diesel oil a large amount of in the fuel tank, the diesel oil in the fuel tank is unfreezed all gradually.In addition, the vehicle in travelling will be monitored the outer storage battery of joining automatically and be owed electric situation and be its charging automatically.
In the driving and the overall process of stopping, what comprise in constant, the fuel tank of diesel fuel temperature in the small-sized fuel reserve tank all liftings of oil temperature and join small-sized lithium storage battery outward owes electricity from filling, keeps full electricity, and whole link is controlled automatically, forms to circulate benignly, without human intervention.
The beneficial effect of low-pressure oil supply system for diesel vehicle of the present invention mainly shows: 1. the diesel-oil vehicle fuel tank connects a small-sized fuel reserve tank, small-sized fuel reserve tank is heated up and is incubated, because small-sized fuel reserve tank volume is little, fast, high insulating effect of temperature rise time, low in energy consumption, can not influence the original performance of vehicle; 2, adopt polyester double-sided insulation electric heating film, pliability is good, can curl, and can make arbitrary shape and double-sided insulation, compared with the electric heating wire heating, lay, change all very simple and easy and safe and reliable, and power as required, select the electric heating film of various resistance values for use, but the emphasis heating-up zone also multilayer lay very convenient practicality; 3, be provided with hot channel in the diesel-oil vehicle fuel tank, can utilize the heating system on the car to prevent that the diesel oil in the diesel-oil vehicle fuel tank from condensing; 4, use is outer joins storage battery, and volume is little, in light weight, can not influence the original performance of vehicle.
