Output device for test of electronic-controlled engine

Abstract

The invention discloses an output device for a test of an electronic-controlled engine. The output device for the test of the electronic-controlled engine is characterized by comprising a signal panel, a damper assembly, a supporting shaft and a spline sleeve, wherein the signal panel is of a circular structure, induction protruding blocks are arranged at the periphery of the circle of the signal panel, a knuckle bearing installing hole is formed in the center of the signal panel, a damper installing hole is formed in the middle of the signal panel, the damper assembly is installed in the damper installing hole, the signal panel is installed at one end of the supporting shaft through a knuckle bearing, one end of the spline sleeve is used in cooperation with the other end of the supporting shaft, and the spline sleeve is fixedly connected with the damper assembly. When the test is carried out, the other end of the spline sleeve is used in cooperation with a spline shaft on a test platform. When the output device for the test of the electronic-controlled engine is used, the coaxiality of the test is high, vibration is low, and information of the rotating speed of a crankshaft can be accurately collected.

Description

Technical field [0001] The invention relates to the field of engine bench testing, in particular to an electronic control engine test output device. Background technique [0002] At present, as national emission standards are becoming more and more stringent, the market demand for electronically controlled engines is increasing. In order to ensure the quality of electronically controlled engines, bench tests are generally performed on engines before they leave the factory. The most fundamental difference between an electronic control engine and a traditional engine is that the electronic control engine uses electronic control technology. For example, in the fuel supply process, in general, the electronic control engine must use sensors to collect power output information from the engine crankshaft. It is different that traditional engines are controlled by mechanical systems. [0003] In the bench test of electronically controlled engines, the requirements for the engine test outp...

AI Technical Summary

Problems solved by technology

[0003] When the electronically controlled engine is tested on the bench, the requirements for the engine test output device are high, and the direct use of the traditional engine test connection tooling has poor coaxiality, is prone to large vibrations, and deviations in the power output process, and there is no corresponding crankshaft sensor. The induction device will cause the data collected by the electronically controlled engine to be distorted or the corresponding data cannot be collected, which will bring obstacles to the test of the electronically controlled engine. Therefore, it is necessary to design an electronically controlled engine test output device that can collect crankshaft speed information
