Electronic throttle valve body for electronic control fuel injection

Abstract

The invention discloses an electronic throttle valve body for electronic control fuel injection, and relates to the technical field of electronic control fuel injection, the electronic throttle valve body comprises a main body assembly, a valve driving assembly is arranged at the top of the main body assembly, a first side cover is connected to the side face of the main body assembly and located outside the valve driving assembly, and an atomization assembly is arranged at the bottom of the main body assembly; the exterior of the main body assembly is connected with a master control assembly, a first injection assembly and a second injection assembly, the first injection assembly and the second injection assembly are the same in structure, the valve driving assembly comprises a servo motor, a connecting rod and a rotating shaft, and by collecting real-time signals of an angle sensor, an ECU controls the servo motor to drive the rotating shaft to rotate; the rotating shaft drives the butterfly valve to rotate so as to adjust the amount of air entering the engine, accurate control over the amount of air entering the engine is achieved, compared with a traditional mechanical stay wire, quicker responsiveness is achieved, the quicker responsiveness is specifically shown as quicker vehicle acceleration performance on an automobile, and torque control and cruise control functions are further achieved.

Description

technical field [0001] The invention relates to the technical field of electronically controlled fuel injection, in particular to an electronic throttle body for electronically controlled fuel injection. Background technique [0002] The existing published patent electronically controlled fuel injection throttle body (publication number: CN105041536A) includes a body, the middle part of the body is provided with several groups of horizontally arranged cavities with openings at the upper and lower ends, and the upper end of the body is provided with an oil circuit , Each cavity is connected with an oil inlet atomization channel, the oil inlet atomization channel is connected with the oil circuit, and the oil inlet atomization channel is provided with a nozzle for controlling the oil inlet, and the lower end of the body is provided with a nozzle for controlling the amount of oil and gas delivered to the engine The valve mechanism is provided with a valve plate matched with eac...

Problems solved by technology

[0003] The above-mentioned patent is a mechanical structure. The angle of the throttle opening and the amount of air entering the engine can only be controlled by the operator. The ECU cannot automatically adjust the opening of the throttle body. At the same time, a stepping motor is used. , throttle position sensor, intake pressure sensor and other components, the overall structure is cumbersome and the integration level is low.
