Electric spray engine speed change working condition calibration and execution system

Abstract

The invention relates to an electric spray engine speed change working condition calibration and execution system, used for quantitative calibration of non-loaded / loaded transition and accelerating and decelerating modes of electric spray engine. The system comprises a throttle body, a computer, a motion control card and an actuating mechanism; wherein the throttle body changes the aperture of a throttle, so as to change the working condition of the engine; the computer acquires corresponding working condition signals of the throttle body and an electric control unit and records the aperture of the throttle and engine parameters at corresponding time; the actuating mechanism is connected with the throttle body, the motion control card issues a control instruction, and the actuating mechanism drives the throttle body to change working condition according to the instruction of the motion control card, thus accurately and flexibly controlling turning angle and angular velocity of the throttle and ensuring consistency of every operation, so that calibration result of engine is more consistent with the actual condition of the engine.

Description

technical field [0001] The invention relates to the technical field of electronic fuel injection engine calibration, specifically an electric fuel injection engine that precisely controls the rotation angle and angular velocity of the throttle body through a motion control card and an actuator, and at the same time ensures the consistency of each throttle body action under the same condition. Engine calibration system. Background technique [0002] In the face of increasingly stringent emission regulations, it is imperative to use EFI technology to reduce fuel consumption and exhaust pollution. The application of EFI technology can simultaneously reduce the emission of harmful substances in the engine exhaust, improve the economy of engine operation, and improve the performance of the engine. On the premise that the software and hardware modes of the electronic control system are basically determined, whether the engine can exert the best overall performance depends on the ...

AI Technical Summary

Problems solved by technology

Usually, the acceleration and deceleration calibration of the EFI engine is realized by manually turning the throttle valve. Every control action of the human body cannot be fully replicated, so it is difficult to make each rotation of the throttle body consistent, resulting in There is a large error between the calibration result and the actual engine working state, and the accuracy of the calibration result cannot be guaranteed
