Description
The divisional application that the application is application number is 201310333893.7, the applying date is 2013.08.04, denomination of invention is water-electricity integrated formula diesel oil intelligent heating equipment, equipment, system and method for work thereof.
Technical field
The present invention relates to automotive field, particularly a kind of water-electricity integrated formula diesel oil intelligent heating system.
Background technique
Diesel car oil supply system is the critical function device of vehicle operating, increases oil plant heating equipment in oil supply system, be for solve diesel oil lower than when 5 DEG C produce wax deposition, cause vehicle cannot normal starting travel problem.
The Basic Mechanism of oil path heating: winter, diesel-oil vehicle ignition difficulties was the old difficult problem that long-standing problem numerous drivers and Vehicle Engineering teacher, its basic reason is: diesel oil can solidify at low ambient temperatures gradually, wax deposition, oil circuit internal resistance is caused to increase, motor oil scavenge pump pressure cannot offset the resistance in oil circuit, causes for shortage of oil or cannot fuel feeding.
Market pre existing hot systems workflow is analyzed: the heating mechanism of the pre-heating system generally adopted in the market is for oil circuit (fuel tank, oil pipe, oil filter etc.) provides thermal source, oil circuit temperature is made to reach about 25 DEG C or install oil scavenge pump additional and increase motor oil scavenge pump suction, to improve the problem of engine oil deficiency by heating.
Existing heating equipment one is at fuel tank and the mid-electric discharge heated filament of oil feed line, the heat produced after electric heating wire energising can impel the oil plant in pipeline to dissolve, but because its heat and heated perimeter are very limited, can not reliably meet amount of fuel supply requirement, and circuit design is simple, Security cannot meet automobile and demand, points out without clear and definite Security simultaneously; Two is the drop tanks setting up high grade oil in main fuel tank, and vehicle is in low temperature or winter job period, and the daily diesel oil all wanting reserve fraction high grade, in order to meet the driving needs in vehicle short-range.Even if two kinds of modes are equipped on same vehicle simultaneously, Dynamic System is very numerous and diverse, operational reliability is low, operation cost is high, causes and occurs the series of problems such as vehicle maintenance expense increases, production operation efficiency is low, service property (quality) can not be guaranteed.
And all there is main logic erroneous judgement in above scheme.Labor is as follows:
For the scheme of existing placement thermal source on the market, the subject matter of engine oil deficiency is diesel oil wax deposition, for reaching engine work state, under using different labels bavin oil condition, and larger for different parts (fuel tank, oil pipe, oil filter etc.) the heating required heat difference of oil circuit.
Diesel oil heat conductivity under the state of liquid is higher, rate of heat exchange is very fast, heating is to diesel oil entirety heating in container, if vessel volume comparatively large (as: fuel tank), then must to ensure in container that all diesel oil is all heated to 25 DEG C of pre-heating systems and just can stops heating, but from the power supply state of vehicle, preheater never may by the so far temperature of the diesel heating in fuel tank, this decision logic, not only cause great energy waste, and the life of product loss of heat energy is very big for providing, if product power is excessive, also can cause expendable infringement to vehicular power-bottle.Meanwhile, the temperature setting of 5 DEG C to 25 DEG C is only directed to 0# diesel oil and uses, and the wax deposition point of high grade diesel oil is lower than 0# diesel oil, and the waste caused is larger with infringement.
And normal logic is, the no matter diesel oil of any label, after being heated to the liquid state that motor can normally start, preheater should stop heating; And when the wax deposition point preheater close to added diesel number should start heating immediately.
For the scheme increasing motor oil scavenge pump suction, it does not change the mobility of diesel oil in essence, even if by force semisolid diesel oil is sucked motor, also can cause misfire because of the poor fluidity of diesel oil, situation about even cannot light a fire.When oil pump cross oil not smooth suck by force and very easily cause damage parts and storage battery power shortage.
Use the mode of diesel pressure in increasing oil circuit with pump type diesel-oil filter, the resistance that the solidification of counteracting diesel oil produces, but its efficiency is lower, need do work large, and along with temperature reduction or pipeline growth, its effect obviously can be deteriorated.Simultaneously fuel pump uses motor to drive, and the efficiency of the higher brushless electric machine of efficiency is general also only about 70%.Therefore be with that the energy consumption of pump type diesel-oil filter is high and efficiency is low, fragile, simultaneously to cause storage battery power shortage.And its structure is obviously more complicated, thus its rate of fault and product cost obviously higher.
The scheme of the scheme and increase motor oil scavenge pump suction of placing thermal source combines and uses by some prior aries, do not solve the root problem of diesel oil wax deposition in essence, diesel oil simultaneously in diesel-oil filter is not enough to the normal use of supply engine, and after the engine started, heating time in diesel-oil filter is too short, the efficiency of heating surface cannot be ensured under secure conditions, so, this mode is not only dealt with problems, and inherits the drawback of this two schemes above on the contrary.
From the angle thinking obtaining thermal source, some companies make an issue of on the heating source of automobile self, because after engine start, the heat of the cooling water in water tank is full, but effectively do not use except being dispersed into except in air, so these are incorporated among fuel tank by the cooling water that heating engines is crossed by the outer circulation of motor by they, the fuel oil in fuel tank heats by the heat unnecessary with cooling water.But motor before being initiated, cooling water in water tank is cold, and the temperature of motor do not reach necessarily require time, the outer circulation of motor can not be opened, need wait engine warming up to a certain extent after cooling water could be incorporated into outer circulation by Inner eycle.So before diesel vehicle starts, this scheme cannot meet the requirement of vehicle cold start-up.Because at a lower temperature, the thickness of the diesel oil in the vehicle oil way do not started, even freezes, and causes motor to start, so water circulation also just cannot be used to heated.
In order to the difficult problem started before solving engine start, a kind of scheme is had to be fuel tank is divided into main fuel tank and drop tank two parts, for in main fuel tank, use low-grade diesel oil, and for adding the diesel oil of high grade in drop tank, before the engine is started, first use the diesel oil of high grade by engine start, after be switched in have in low-grade main fuel tank, reach the object of diesel-oil vehicle cold start-up in winter.
But the program needs special fuel tank, and need two-way return tube, cost is higher, and higher for the requirement on machining accuracy of the separation layer in fuel tank, reveals once produce, the oil of its high grade mixes with low-grade oil, also just cannot reach the object of cold start-up under low temperature.
Further, before parking, the diesel oil of high grade must be ensured to be full of oil circuit, its control time requires very accurate, and overlong time causes waste, and the time is too short cannot be full of oil circuit by the oil of high grade again.User cannot accurately be manipulated.
All there is certain defect and hidden danger in existing product software, hardware.The control logic of software fundamentally cannot solve the difficult problem of diesel-oil vehicle igniting in winter, and functionally also cannot reach the requirement of automobile industry vehicle safety performance module.In quality of hardware, also cannot reach the automotive grade safety standard of country.This is great potential safety hazard concerning user.Therefore, address these problems extremely urgent.
The present invention is understanding on basis to the analysis of domestic most of oil way of diesel vehicle electric heating product, and in conjunction with the situation of domestic actual oil product and vehicle, a new generation developed meets the pre-heating system of automotive grade safety standard and actual vehicle operating mode.
