Abstract
The utility model discloses a digital electronic speed regulator system control device of a fuel injection pump. Signals of a water temperature sensor, an oil pressure sensor, an air inlet temperature sensor, an air inlet pressure sensor of a diesel engine pass through protection function wiring harnesses, signals of a rotating speed sensor pass through electronic speed regulator connection wiring harnesses and are respectively connected with a digital electronic speed regulator electronic control unit, signals of a relation MAP of the position of a fuel injection pump rack rod which is calibrated on a fuel injection pump test stand rack and the circulation fuel injection amount can be input to the digital electronic speed regulator electronic control unit through a calibrating wiring harness by a calibrating tool, a feedback signal of the digital electronic speed regulator electronic control unit can be sent to a digital electronic speed regulator actuator which is arranged on a fuel injection pump component through the digital electronic speed regulator connection wiring harnesses, and the digital electronic speed regulator electronic control unit is in communication through an integrated wiring harness bus. According to the digital electronic speed regulator system control device disclosed by the utility model, the operation is very convenient, the installation of the fuel injection pump of the diesel engine cannot be affected, the matching of an original fuel system also cannot be changed, and the dynamic property and the economic efficiency of using the diesel engine are better optimized.
Description
Technical field
The utility model relates to a kind of conventional diesel engine Injection Pump and joins the digital electronic governor system controller, and particularly a kind of in-line fuel injection pump is joined the digital electronic governor system controller.
Background technique
The conventional diesel engine Injection Pump is joined the mechanical governor system controller, be according to diesel engine under difference running operating mode, by the mechanical governor system that is formed by a series of component such as flying iron, spring, connecting rod, governor lever, bolt, control Injection Pump ratch position, the fuel injection quantity of Injection Pump is regulated in realization.This mechanical governor control system, because complex structure, processing cost height not only, and mechanical failure takes place easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Injection Pump digital electronic governor system controller, change the mechanical governor parts of conventional diesel engine jetting pump speed regulating machine assembly into digital electronic governor, keeping under the constant prerequisite of former injection pump plunger structural parameter, adopt Injection Pump ratch position and the relation of controlling electric current, realized the precise figures chemical control system of Injection Pump oil mass.Combination as traditional hydraulic injection pump and hyundai electronics control technique is used for realizing the control of the multiple mode of operation of diesel engine.
The utility model is to realize like this; Injection Pump digital electronic governor system controller; the cooling-water temperature sensor of diesel engine; oil pressure sensor; intake air temperature sensor; the signal of air inlet pressure sensor is by the protective function wire harness; the signal of speed probe is by the electronic speed regulator rat tail; be connected with the digital electronic governor electronic control unit respectively; the signal that calibration tool concerns MAP figure with the Injection Pump ratch position demarcated on the fuel injection pump tester frame and circulating fuel injection quantity; by demarcating the pre-input digit electronic speed regulator of wire harness electronic control unit; digital electronic governor electronic control unit feedback signal sends to the numeral electricity that is installed on the Injection Pump parts by the digital electronic governor rat tail and transfers final controlling element, and the digital electronic governor electronic control unit communicates contact by integrated linear speed bus.
Because this device adopts in-line fuel injection pump, so adapted digital electronic speed regulator is easy to operate, does not influence the installation of diesel injection pump, does not also change the coupling of former oil-fired system, power character and Economy that diesel engine uses have been optimized better.
Description of drawings
Fig. 1 is diesel injection pump digital electronic governor system controller working principle schematic representation.
Among the figure, 1 is diesel engine, and 2 is the Injection Pump parts; 3 is that the numeral electricity is transferred final controlling element, and 4 is the digital electronic governor rat tail, and 5 is the digital electronic governor electronic control unit; 6 is the protective function wire harness; 7 for demarcating wire harness, and 8 is calibration tool, and 9 is speed probe; 10 is oil pressure sensor; 11 is cooling-water temperature sensor, and 12 is intake air temperature sensor, and 13 is air inlet pressure sensor.
Specific embodiment
As shown in Figure 1; Injection Pump digital electronic governor system controller; diesel engine 1; cooling-water temperature sensor 11; oil pressure sensor 10; intake air temperature sensor 12; the signal of air inlet pressure sensor 13 is by protective function wire harness 6; the signal of speed probe 9 is by digital electronic governor rat tail 4; respectively with digital electronic governor electronic control unit 5(ECU-Electronic Control Unit) be connected; calibration tool 8 will concern that the signal of MAP figure is input to digital electronic governor electronic control unit 5 in advance by demarcating wire harness 7 by the Injection Pump ratch position under the different rotating speeds of demarcating on the fuel injection pump tester frame and circulating fuel injection quantity; digital electronic governor electronic control unit 5 feedback signals send to the numeral electricity that is installed on the Injection Pump parts 2 by digital electronic governor rat tail 4 and transfer final controlling element 3; digital electronic governor electronic control unit 5 communicates contact by harness-integrated CAN bus; during work; digital electronic governor electronic control unit 5 is collected speed probe 9; cooling-water temperature sensor 11; oil pressure sensor 10; intake air temperature sensor 12; feedback signals such as air inlet pressure sensor 13; Injection Pump ratch position and circulating fuel injection quantity according to pre-input digit electronic speed regulator electronic control unit 5 concern MAP figure; feedback signal is transferred final controlling element 3 by the numeral electricity that digital electronic governor rat tail 4 is sent on the Injection Pump parts 2, in order to the diesel engine external characteristics of control under different operating conditions; various mode of operations such as governor control characteristics desired Injection Pump ratch position or fuel injection quantity.Calibration tool 8 and demarcation wire harness 7 also can be realized work monitoring and the fault diagnosis functions under the diesel engine operating condition.
Because this device adopts the diesel engine in-line fuel injection pump, adapted digital electronic speed regulator system control gear does not influence the assembling of diesel engine, can not change the coupling of former oil-fired system yet, optimized power character and Economy that diesel engine uses better, Operation and maintenance are very convenient.
