The flange surface has a idling channel, a idling control valve, a position sensor, a inlet pressure sensor, a inlet temperature sensor, and an electric control unit ECU, while said position sensor, inlet pressure sensor and inlet temperature sensor can directly transmit the signal to the ECU via pins, while the ECU can directly transmit the control signal via pins to the idling control valve. The invention combines the electric control unit, several sensors and idling control valve on the air-saving gate as air-saving gate integration to improve the anti-disturb ability of electric control unit, solve he compatibility of air-saving gate with 50-250cc motorcycle electric-injection system and reduce the cost.
Description
One, technical field
The present invention relates to the electrospray throttle valve control unit that motor car engine is used, particularly the electrospray throttle valve control unit of 50-250cc motorcycle and MPV (Multi-Purpose Vehicle) (ATV).
Two, background technique
Because technology and cost mainly are the factors of cost, motorcycle electric spraying system is lower in medium and small discharge capacities such as 50-250cc, price, fail to be applied on the motorcycle of output and recoverable amount maximum always.Along with the growing interest of the whole world to environment, beginning in Europe that motorcycle was implemented Europe III in 2006 discharges, 2008 begin motorcycle is implemented to be equivalent to the state III discharging of Europe III in China, and each motorcycle producer falls over each other to adopt electric jet technology to become the incontrovertible fact to satisfy following emission request.
Its structural configuration of electric injection system that present stage is used for big discharge capacity motorcycle all is a distributing, the throttle body that system has, ECU, various sensor and control valve are arranged apart on motor and vehicle body, position transducer, IACV (Idle Air Control Valve) and some other mechanical parts often only are housed on the throttle body, and the core component electronic control unit (ECU) that is used for engine operation is controlled comprehensively is not installed in throttle body.On the one hand, because each part all needs special protection more than arranged apart the making of ECU, sensor, control valve, increased cost; On the other hand, along with the difference of engine model, throttle body mounting structure difference, the motorcycle electric spraying system of different model can not be compatible, makes the development cost of motorcycle electric spraying system increase; At last, because ECU and throttle body are arranged apart, then a large amount of real-time data signals of the sensor on ECU and the throttle body, control valve have to exchange by the lead transmission, cause antijamming capability to reduce.
Three, summary of the invention
The objective of the invention is the problem and shortage part that exists at prior art and a kind of strong anti-interference performance that provides, to compatible good, the electrospray throttle valve control unit assembly for motorcycle that cost is low of the motorcycle electric spraying system of different model.
The object of the present invention is achieved like this: a kind of electrospray throttle valve control unit assembly for motorcycle, comprise body, throttle plate pin, throttle blade, swing frame assembly parts, torsion spring, it is characterized in that, the integrated flanged surface that is provided with offers the idling passage on the described body on the flanged surface, and IACV (Idle Air Control Valve), position transducer, air inlet pressure sensor and intake air temperature sensor are installed; Also be fixed with electronic control unit ECU on the flanged surface; Above-mentioned position transducer, air inlet pressure sensor and intake air temperature sensor directly reach ECU with signal by pin.
Described swing frame assembly parts is two R swing frame assembly parties: its swing frame is provided with two acceleration cable mounting holes not equidistant with its center of rotation; Described body is provided with four structure hole for the support installation, and these four structure hole are with the rectangular layout of the center of rotation of swing frame.
Described throttle blade diameter is 16-34mm.
Than prior art, the outstanding feature and the beneficial effect of technical solution of the present invention are:
The present invention with IACV (Idle Air Control Valve), electronic control unit ECU and multiple sensors (position transducer, air inlet pressure sensor, intake air temperature sensor etc.) thus the flanged surface all by a unified size is integrated in forms throttle valve control unit assembly on the tb.Multiple sensors directly reaches ECU with signal by pin.Like this, cancelled original connection lead first and changed the distribution form that dispersion is provided with, thereby reduced cost; Second sensor pin directly is connected with ECU, has improved the antijamming capability of ECU system; Adopt the flanged surface of a unified size, can be adaptive at random with the motorcycle electric spraying system of different model; In the 16-34mm scope, select closure bore (being the throttle blade diameter), make the present invention can be applicable to 50-250cc motorcycle ATV car electric injection system; Owing to adopt two R swing frame assembly parties that two different backguy mounting points are arranged on it, therefore, all can satisfy the requirement that the swing frame assembly parts is rotated on prescribed direction for the motorcycle electric spraying system of different mounting points; Support optionally is installed on a plurality of different direction of center of rotation of swing frame, thereby guaranteed electric injection system throttle valve unit working in any direction.
