Preferably, said heat-exchanger rig is a heat exchanging tube.
Preferably, the outer surface of said fuel tank is provided with thermal insulation layer.
Preferably, said control gear is installed in the operator cabin of automobile.
Preferably, said main fuel tank and said drop tank separate through a dividing plate.
Preferably, the pipeline that said heat-exchanger rig is connected with said intake pipe or outlet pipe is provided with a water route control valve, and said water route control valve is connected with said control gear.
Technique scheme has following beneficial effect: the automatic temperature elevation system of this diesel engine diesel oil injects the higher gasoline of label in use in main fuel tank, in drop tank, inject the lower gasoline of label; Like this when motor is worked under the lower environment of temperature; Can be at first through drop tank to engine oil, make engine start work, when engine operation after a period of time; The heat of engine producing is through the higher diesel oil of heat-exchanger rig heating main fuel tank internal label; Diesel oil in the main fuel tank can use under the lower environment of temperature like this, can control opening of oil passage control valve on the main fuel tank oil pipe through control gear at this moment, makes closing of oil passage control valve on the drop tank oil pipe simultaneously; Give engine oil by main fuel tank; So just can make DENG under the lower environment of temperature, use the higher diesel oil of label, thereby reduce driver or operation personnel's operation cost, reduce it at fuel oil disbursement easily.
Above-mentioned explanation only is the general introduction of the utility model technological scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, below this patent is elaborated with the preferred embodiment and the conjunction with figs. of the utility model.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1, the automatic temperature elevation system of this diesel engine diesel oil comprises motor 1, fuel tank 6 and water tank, and motor 1 is provided with intake pipe 3, outlet pipe 2, return tube 4 and fuel supply line 5, and intake pipe 3, outlet pipe 2 are connected with water tank motor 1 is cooled off.The outer surface of fuel tank 6 is provided with thermal insulation layer, can the diesel oil in the fuel tank be incubated through thermal insulation layer, prevents that the heat in the fuel tank 6 outwards scatters and disappears.
Be provided with a dividing plate 9 in the fuel tank 6; Dividing plate 9 is divided into main fuel tank 7 and drop tank 8 two-part with fuel tank; Main fuel tank 7 is connected with return tube 4, fuel supply line 5 through main fuel tank oil pipe 12,13 respectively, and drop tank 8 is connected with return tube 4, fuel supply line 5 through drop tank oil pipe 10,11 respectively.Be equipped with an oil passage control valve 14 on main fuel tank oil pipe 12,13 and the drop tank oil pipe 10,11, oil passage control valve 14 is used to control the break-make of corresponding oil pipe, and oil passage control valve 14 is connected with control gear, the break-make of control gear may command oil passage control valve 14.This control gear can be designed to automatic control mode oil passage control valve is controlled; Also can be designed to manual control mode controls; When being designed to manual control mode, this control gear should be installed in the operator cabin of automobile, can make things convenient for driver to operate like this.
