Description
Technical field
The present invention relates to a kind of fuel delivery control system on flat fuel tank.
Background technology
Along with China's automotive technology level improves constantly, and the fast development of urban highway, low floor low entry automobile can improve safety of getting on or off the bus, and improves passenger getting on/off speed, is convenient to disabled person by bus; Particularly low floor low entry city bus will have larger development space, and low floor low entry city bus is a direction of city bus development from now on.
But the constructional feature lower due to low floor low entry car chassis vehicle frame distance ground and sufficient fuel tank capacity demand, fuel tank layout adopts 2 ~ 3 highly relatively short flat fuel tanks more.At automobile up slope, descending or when accelerating anxious deceleration at automobile emergency, the technical barrier that the oil suction dish of flat fuel tank easily sucks air needs solution badly.
Summary of the invention
The present invention seeks to: a kind of fuel delivery control system on flat fuel tank is provided, be intended to solve adopt the automobile of flat fuel tank going up a slope, descending or accelerate anxious deceleration at automobile emergency time, the oil suction dish of flat fuel tank easily sucks the technical barrier of air.
Technical scheme of the present invention is: a kind of fuel delivery control system on flat fuel tank, comprise several the flat fuel tanks be arranged on automobile, the oil-feed port of each flat fuel tank is all connected with oil suction dish, and be connected by fuel feed pipe between oil suction dish and the engine installation of automobile, be provided with in each fuel tank near the oil-feed port being positioned at this fuel tank, for detecting the fuel sensor of oil-feed port place amount of fuel, fuel feed pipe is provided with oil pipe Controlling solenoid valve, and described fuel sensor and oil pipe Controlling solenoid valve are all electrically connected with an oil circuit Management Controller.
As preferably, described oil circuit Management Controller is connected with a fuel gage by CAN.
Advantage of the present invention is: control logic relation of the present invention is simple, and cost of development is relatively low; When efficiently solving at automobile up slope, descending or accelerate anxious deceleration at automobile emergency, the oil suction dish of flat fuel tank easily sucks the technical barrier of air;
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
The structural representation that Fig. 1 is the embodiment of the present invention;
Wherein: the flat fuel tank of 1-, 2-fuel feed pipe, 3-fuel sensor, 4-fuel gage, 5-oil pipe Controlling solenoid valve, 6-oil return pipe, 7-engine installation, 8-T-pipe joint, 9-oil circuit Management Controller.
Detailed description of the invention
Fig. 1 illustrates a specific embodiment of the fuel delivery control system of the present embodiment on flat fuel tank, it comprise in several the flat fuel tank 1(figure be arranged on automobile illustrate two), the oil-feed port of each flat fuel tank 1 is all established and is connected with oil suction dish (not shown), and the engine installation 7(of oil suction dish and automobile is as automotive engine) between be connected by fuel feed pipe 2.Be provided with in each fuel tank 1 near the oil-feed port being positioned at this fuel tank, for detecting the fuel sensor 3 of oil-feed port place amount of fuel, fuel feed pipe 2 is provided with oil pipe Controlling solenoid valve 5, and described fuel sensor 3 and oil pipe Controlling solenoid valve 5 are all HG6142 with an oil circuit Management Controller 9(model) be electrically connected.
The principle of work of the present embodiment is as follows:
When each fuel sensor 3 detects that the oil-feed port place of each flat fuel tank 1 all has enough amount of fuels, when determining that oil suction dish can both be drawn onto fuel oil, the oil pipe Controlling solenoid valve 5 that oil circuit Management Controller 9 can control on each fuel feed pipe 2 is respectively opened, fuel oil sends engine installation 7 to after oil pipe T-pipe joint 8 collects, and part fuel oil is along oil return pipe 6 oil return in one of them flat fuel tank.
When a certain fuel sensor 3 detects the fuel oil at a certain flat fuel tank 1 oil-feed port place less (reaching the alarm set point of setting), the oil suction dish corresponding with this fuel tank has when inhaling less than fuel oil dangerous, oil pipe Controlling solenoid valve 5 on oil circuit Management Controller 9 meeting control oil pipe 2 is closed, this oil suction dish stops oil suction, all the other oil suction dishes work on, supply the energy to engine installation 7, part fuel oil is along oil return pipe 6 oil return in one of them flat fuel tank.
In addition, in the present embodiment, described oil circuit Management Controller 9 is also connected with a fuel gage 4 by CAN.When each fuel sensor 3 all detects that the fuel oil in fuel tank is less, reach the alarm set point of setting, each oil suction dish has when inhaling less than fuel oil dangerous, and oil circuit Management Controller 9 provides information by CAN to fuel gage 4, and fuel gage 4 sends alerting signal.
Fuel sensor 3 provides fuel tank fuel quantity signal and oil starvation alarm message to oil circuit Management Controller 9, oil circuit Management Controller 9 provides the working power of oil pipe Controlling solenoid valve 5, the information that oil circuit Management Controller 9 provides according to fuel sensor 3, the opening and closing of control oil pipe Controlling solenoid valve 5.
Oil circuit Management Controller 9 provides oil mass information in fuel tank and oil starvation alarm message by CAN to fuel gage 4, and wherein oil mass information takes from each fuel sensor 3 aviation value; When oil starvation alarm message only has all fuel sensors 3 to send warning simultaneously, oil circuit Management Controller 9 is just supplied to fuel gage 4 oil starvation alarm message.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
