Abstract
The utility model relates to an electronic-control fuel injection system. An actuator is installed in a speed regulator of an injection pump, an electronic-control unit ECU is connected with the speed regulator, a fuel preliminary filter and a fuel fine filter in a fuel tank are connected with a pipe of the electronic-control injection pump, and an electronic-control fuel injector is connected with a high-pressure fuel pipe. The utility model has the advantages of low investment, simple method of installation, achievement of dynamic control and capacity of reaching the best working state of an engine part.
Description
Technical field:
The utility model relates to a kind of electronic-controlled injection system, is mainly used in diesel engine.
Background technique:
At present, along with automobile emission regulation requires more and more stricter, advanced country has begun to widely apply electric-control diesel engine in the world, and the key that realizes electric-control diesel engine is the employing of electronic control injection system, mainly contains automatically controlled VE pump, electrically-controlled pump nozzle, electronically controlled unit pump, heui fuel injection system and co-rail oil injection system etc. at present in the world.But China's diesel engine only just developed rapidly at nearly 10 years, the motor that belongs to low-cost low technical content, along with China's entry into the WTO, automotive industry is faced with serious challenge, especially as the diesel engine of power assembly, to integrate with international advanced technology, injection system technology as the diesel engine heart must integrate with the world in advance, this just requires diesel engine using electronic control injection system, and above-mentioned external electronic control injection system is fit to be applied on the motor newly developed, the cost height has high input like this, and it is long to produce setup time.
Summary of the invention:
The purpose of this utility model is to provide a kind of electronic-controlled injection system, drops into very for a short time, and mounting type is constant.Realize dynamic control, can realize Flexible Control, can satisfy the best requirement of each performance of operating condition of motor; Can realize that fuel injection beginning time and end of injection time dynamically controls.
The technical solution of the utility model is achieved in that electronic-controlled injection system, form by the various sensors of fuel tank, low pressure line, fuel preliminary filter, fuel oil fine cleaner, electrical control oil spray pump, pressure duct, electric-controlled fuel injector, oil sprayer and Injection Pump return tube, motor, ECU (Electrical Control Unit) etc., it is characterized in that: final controlling element is installed in the jetting pump speed regulating machine, ECU (Electrical Control Unit) ECU links to each other with speed regulator, fuel preliminary filter in the fuel tank links to each other with the pipeline of electrical control oil spray pump with the fuel oil fine cleaner, is connected with high-pressure oil pipe on the electric-controlled fuel injector.
Good effect of the present utility model is: drop into very for a short time, mounting type is simple; And realized dynamic control, can make the engine section operating mode reach optimum Working.
Description of drawings:
Fig. 1 is a fundamental diagram of the present utility model;
Fig. 2 is the structural representation of oil sprayer of the present utility model.
Concrete mode of execution:
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, electronic-controlled injection system, by fuel tank 1, low pressure line, fuel preliminary filter 2, fuel oil fine cleaner 3, electrical control oil spray pump 4, pressure duct 5, electric-controlled fuel injector 6, oil sprayer and Injection Pump return tube, the various sensors 7 of motor, ECU (Electrical Control Unit) 8 compositions such as grade, it is characterized in that: final controlling element is installed in the jetting pump speed regulating machine 9, ECU (Electrical Control Unit) ECU8 links to each other with speed regulator 9, fuel preliminary filter 2 in the fuel tank 1 links to each other with the pipeline of fuel oil fine cleaner 3 with electrical control oil spray pump 4, is connected with high-pressure oil pipe 5 on the electric-controlled fuel injector 6.
System passes through the fuel oil oil inlet pipe with fuel oil from fuel tank 1 under the oil transfer pump effect of Injection Pump, fuel preliminary filter 2, enter Injection Pump 4 low pressure oil pockets behind the fuel oil fine cleaner 3, work through Injection Pump 4 is compressed into high pressure oil by high-pressure oil pipe 5 arrival electric-controlled fuel injectors 6 with low pressure oil, pass to ECU (Electrical Control Unit) 8 according to the needs of Under Different Work Condition of Engine and with the data that the various sensors 7 of motor are gathered then, handle the back by ECU (Electrical Control Unit) 8 and send instruction to electrical control oil spray pump 4, adjust the needed fuel injection quantity of motor by automatically controlled speed regulator 9, ECU (Electrical Control Unit) is sent to instruct and is made oil sprayer determine the fuel injection beginning time according to the requirement (being motor injection system matching and calibration arteries and veins spectrogram) of engine operating condition for electric-controlled fuel injector 6 simultaneously, the end of injection time, reasonably mate adjustment by electronic control system and mechanical system like this, make the requirement of motor, realize optimum Working according to each operating mode.
