The control device of the electric fuel pump is arranged between the electric fuel pump and an automobile engine; an oil supply pipeline and an oil return pipeline are connected between the engine and an automobile oil tank; the electric fuel pump is connected to the oil supply pipeline; the control device includes a flow controller and an oil return flow detector; the flow controller is connected with the electric fuel pump; the oil return flow detector is arranged in the oil return pipeline and connected with the flow controller; and the flow controller receives the signals transmitted by the oil return flow detector, so as to adjust the output flow rate of the electric fuel pump. The utility model has the advantages that the control device of the electric fuel pump can meet the fuel demand of an engine under different working environments, and at the same time avoids increasing fuel consumption due to overmuch fuel conveying.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of control gear of electric fuel punp.
Background technique
Automobile is a part indispensable during people live as a kind of the most frequently used means of transportation, yet along with the continuous increase of automobile pollution, automobile also increases day by day to the consumption of fuel oil.At present, fuel resource is comparatively limited, and how reducing automobile as much as possible is the problem that people pay close attention to the consumption of fuel oil.
Automobile is the power that fuel delivery is provided by oil pump to the consumption of fuel oil, and fuel oil is burnt in fuel tank is transported to the motor of automobile.For satisfying the fuel demand of automobile at various working environments, the output flow of oil pump of the prior art is firm discharge and is designed to the peak rate of flow that motor consumption can reach.
Though this design can make motor all can obtain enough fuel oils under various operating conditions,, the required fuel flow of automobile real work is in a lower level mostly, reaches the required peak rate of flow of motor far away.Oil pump often makes most of fuel oil flow back into once again in the fuel tank for motor provides the fuel oil of peak rate of flow constantly, causes the fuel molecule activity to strengthen, and causes oil pump to flog a dead horse, and has accelerated the consumption of fuel oil indirectly.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, and having proposed a kind ofly can provide the control gear of the electric fuel punp of suitable amount of fuel for it according to the real work demand of motor.
The purpose of this utility model can realize by following technical proposal: a kind of control gear of electric fuel punp, be located between electric fuel punp and the motor car engine, be connected with oil feed line and return line between motor and the automotive oil tank, above-mentioned electric fuel punp is connected in the oil feed line, it is characterized in that, this control gear comprises a flow dontroller and an oil return flow detector, described flow dontroller and described electric fuel punp link, described oil return flow detector is located in the described return line and described oil return flow detector and flow dontroller link, and described flow dontroller receives signal that the oil return flow detector passed and adjusts the output flow size of described electric fuel punp with this.
Be provided for detecting the oil return flow detector of return line intermediate fuel oil flow in the return line of the control gear of this electric fuel punp between motor car engine and fuel tank, unnecessary amount of fuel also sends to flow dontroller with this information after the detection of engine fuel consumption constantly, flow dontroller is judged the fuel oil situation that the motor real work is required according to the represented oil return flow of this information and is controlled electric fuel punp and regulate its output flow, satisfies the fuel demand of the actual use of automobile.
In the control gear of above-mentioned a kind of electric fuel punp, also be connected with control circuit between described flow dontroller and the electric fuel punp, described flow dontroller can be controlled the working power of electric fuel punp by control circuit.
In the control gear of above-mentioned a kind of electric fuel punp, described oil return flow detector is a flow transducer.
In the control gear of above-mentioned a kind of electric fuel punp, described oil return flow detector is an electronic flowmeter.
Compared with prior art, the control gear of this electric fuel punp by the mode of closed loop control gather between motor and the fuel tank recirculating oil quantity and according to the working power of the different adjustment electric fuel punp of recirculating oil quantity, can satisfy the fuel demand of motor under the different operating environment, can avoid again causing the situation of fuel consume aggravation to occur because of the fuel delivery amount is excessive.
Description of drawings
Fig. 1 is the structural representation of the control gear of this electric fuel punp.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the control gear of this electric fuel punp comprises flow dontroller and oil return flow detector, be arranged between motor car engine, electric fuel punp and the automotive oil tank, motor car engine, automotive oil tank and electric fuel punp connect successively by pipeline and form loop.Wherein, electric fuel punp also is connected with the car load power supply by the contact of a FP Fuel Pump Relay, and the coil of this FP Fuel Pump Relay and electronic control unit ECU link.In the present embodiment, be connected with oil feed line and return line between motor car engine and the automotive oil tank, electric fuel punp is connected in the oil feed line; Flow dontroller links by control circuit and electric fuel punp and can control the working power of electric fuel punp, and the oil return flow detector is a flow transducer, is arranged on the return line between motor and the fuel tank and with flow dontroller to link.
When the car owner turns to the ON shelves by car key with ignition switch, electronic control unit ECU collects this signal and controls the coil electricity of FP Fuel Pump Relay, at this moment, and the make contact of FP Fuel Pump Relay, the car load power supply begins to make the car load oil pressure reach setting value in 2 seconds in advance to the electric fuel punp power supply.Then, FP Fuel Pump Relay disconnects.When automobile starting, the contact of FP Fuel Pump Relay is closed again, and electric fuel punp is accepted the continued power of car load power supply and fuel oil is transported to motor from the fuel tank place, and after motor consumed the part fuel oil, remaining fuel oil was then got back in the fuel tank by pipeline.
At this moment, being arranged at flow transducer between motor and the fuel tank detects the oil return flow in the pipeline and flow information is sent to flow dontroller, flow dontroller is judged the required amount of fuel of motor real work according to this flow information and is regulated the working power of electric fuel punp by control circuit, make the amount of fuel that refluxes in the pipeline between motor and the fuel tank remain on a lower steady state value, the needs of motor real work had both been satisfied, reduce the idle work that electric oil pump is done again, reduced fuel consume.In addition, how much the fuel flow returns amount can adjust freely according to the difference of automobile.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
