Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified, so that those skilled in the art better understand the present invention, following explanation only is exemplary.
As shown in Figure 1; A kind of automobile-use low-temperature prewarming device; It comprises fuel Heating unit, operator cabin heating unit, oil sump heating unit and oil supply system heating unit, and wherein the fuel Heating unit has fuel heater 3, and fuel heater 3 has water intake, water outlet, fuel sucking pipe 13 and return tube 14; Said water intake is communicated with the cold shell 1-1 of the machine of motor 1, and fuel sucking pipe 13 links to each other with fuel oil fuel oil fuel tank 12 with return tube 14; The operator cabin heating unit comprises the radiator 4 that is arranged in the operator cabin; Radiator 4 water inlets place link to each other with the water outlet of fuel heater 3 through intake pipe 25; Radiator 4 water outlets place connect a port of a cross fitting 5 through return pipe 17; These cross fitting 5 other three ports connect warm braw 21, swelling water tank 23 and thermostat 1-2 respectively, and thermostat 1-2 connects water tank 22 and passes through the water cavity that water pump 24 connects motors 1, connect the effect of the port starting venting of swelling water tank 23; The oil sump heating unit comprises the oil sump heating pipe 6 in the oil sump 1-3 that is arranged on motor 1, and oil sump heating pipe 6 one ends connect the cold shell 1-1 of machine of motor 1, and the other end links to each other with fuel heater 3 water intakes; The oil supply system heating unit comprises heating heating fuel tank 7, inlet pipeline 8, water return pipeline 10, fuel-displaced pipeline 9 and return line 11; Heating fuel tank 7 inside are provided with heating sensor 7-1; Heating sensor 7-1 is communicated with the cold shell 1-1 of the machine of motor 1 through inlet pipeline 8; Link to each other with fuel heater 3 water intakes through water return pipeline 10, fuel-displaced pipeline 9 and return line 11 are communicated with the filler opening and the return opening of motor 1 respectively.
The cold shell 1-1 of the machine of said motor 1 place is provided with a tapped hole, and this tapped hole is provided with the water pipe adapter 2 that is used to connect water pipe 15, and the cold shell 1-1 of slave place provides circulatory mediator for fuel heater 3 easily.
Said fuel heater 3 is heating equipments relatively independent with motor; It burns through the high grade diesel oil in the fuel sucking pipe 13 draw fuel fuel tanks 12 under the situation that motor 1 does not have to start; Discharge the thermal source of certain heat as preheating, the most unnecessary diesel oil that do not burn flows back to fuel oil fuel tank 12 through return tube 14.
Said radiator 4 is arranged in the operator cabin, by means of by the circulating liquid of fuel heater 3 heating, improves the temperature in the operator cabin.
Said oil sump heating pipe 6 hover above oil suction dish in the oil sump around, in order to increase the area of contact of heating pipe and machine oil as far as possible, can it be made as the shape of coiler or volute.
In the said heating fuel tank 7 be low grade diesel oil, under the effect of the heating sensor 7-1 that the circulating liquid of built-in fuel heater 3 capable of using heats, keeps the normal viscosity of fuel oil, avoids the fuel oil wax deposition.
In order to keep the unimpeded of oil circuit; Prevent the fuel oil wax deposition obstruction oil pipe in the fuel pipe; The water return pipeline 10 of the inlet pipeline 8 of heating fuel tank 7 and fuel-displaced pipeline 9 and heating fuel tank and return line 11 are taked the form of embedding tube, keep the normal viscosity of fuel oil through the heat exchange of circulating liquid and fuel oil.
Consider the convenience of control and maintenance, said motor leads on water pipe 15 and the outlet pipe 17 of fuel heater and all is provided with control valve 16.
When considering Parking; Oil sump 1-3 and heating heating fuel tank 7 do not have necessity of heating; The ad hoc parallelly connected water pipe 18 that is in parallel with oil sump heating pipe 6 and inlet pipeline 8, water return pipeline 10 of putting can be separately that operator cabin heats to realize from the circulating liquid that motor comes out.Wherein, On the parallel connection water pipe 18 the normally closed control valve 19 of electromechanical is set; Before oil sump heating pipe 6 and heating fuel tank 7 inlet pipelines 8 electromechanical is set and often opens control valve 20; In order to realize preset heating function, the two be the interlock type setting, and those skilled in the art can expect that normally closed control valve 19 of electromechanical and electromechanical often open control valve 20 and can adopt other control valves replacements certainly.
Utilize working procedure of the present invention following:
Before motor carries out cold-starting, open the control valve 16 on fuel heater 3, water pipe 15 and radiator 4 return pipes 17, starting fuel heater 3 and radiator 4.Impelling under the effect of the water pump on the fuel heater 3; Get into the heating chamber of fuel heater 3; The flowing medium that continues heated engine-cooling system is at first through the radiator 4 in the operator cabin, and under the heat effect that radiator 4 distributes, the temperature in the operator cabin constantly raises; The cross fitting 5 of the water outlet of radiator 4 before through thermostat 1-2 on the motor 1 is endlessly in the flow direction engine 1; Through oil sump heating pipe 6 and the inlet pipeline 8 of heating heating fuel tank 7 and the heating chamber that water return pipeline 10 flow back to fuel heater 3 of water pipe adapter 2 in oil sump 1-3 at the cold shell 1-1 of machine place on the motor 1, through the impel circulation of effect under again carrying out a new round of fuel heater 3 heating at water pump.Through the heat exchange action of medium, continue heating operator cabin, engine cylinder-body, oil sump, fuel oil, treat can pilot engine when motor 1 interior water temperature reaches uniform temperature.At this moment, the machine oil in the oil sump maintains normal viscosity through the effect of oil sump heating pipe 6, can arrive required lubricated place rapidly; Low grade diesel oil has also been avoided the wax deposition phenomenon, under the effect of the oil scavenge pump of motor, gets in the motors 1 smoothly through fuel-displaced pipeline 9; Do not have the diesel oil of after-flame to flow back to heating heating fuel tank 7, can significantly reduce engine scuffing, oil consumption and toxic emission in this case, prolong engine life through return line 11; Improve the adaptability of motor; And can use low grade diesel oil, improve the power of motor under the low temperature environment, improve the Economy of motor.After motor 1 starting, warm braw 21 is opened, and under the booster action of radiator 4, impels the temperature in the operator cabin 1 constantly to raise jointly, makes to keep certain temperature in the operator cabin.When reaching a certain, the temperature of circulatory mediator goes up in limited time; Fuel heater 3 stops automatically, when temperature be reduced to a certain down in limited time, fuel heater 3 again can normal starting; Make circulatory mediator can remain on a certain temperature range; Thereby, make under the temperature of cold, but can keep as warm as spring effect in the operator cabin.
If after the engine start or the long-time Parking of vehicle need not heat the time to the oil sump 1-3 of motor 1 and fuel oil; Can handle the normally closed control valve 19 of interlocking electromechanical and often open control valve 20 with electromechanical; The normally closed control valve 19 of electromechanical is opened; Electromechanical is often opened control valve 20 and is closed, and the circulating liquid that comes out through the cold shell 1-1 of machine place's water pipe adapter 2 then directly gets into the heating chamber of fuel heater 3, and heat medium is just only at heater 3, radiator 4 like this; Circulate between the cylinder body of motor 1, thereby make the higher temperature of the interior maintenance of operator cabin.
Basic principle of the present invention and advantage have more than been described.The present invention is not restricted to the described embodiments, and in the prerequisite that does not break away from the scope of the invention, those skilled in the art can do many variations and improvement as required, as: the oil sump heating pipe can be connected with the inlet pipeline 8 of oil supply system heating unit.Protection domain of the present invention should be defined by appending claims and equivalent thereof.
