AI Technical Summary

Technical Problem

The existing engine performance testing methods cannot effectively monitor the entire branch flow resistance of the engine, and there are safety hazards when drilling holes in the engine, which may lead to oil leakage or engine scrapping.

Method used

An engine flow resistance test device is designed without drilling holes in the engine and without changing the oil channel. It uses an ultrasonic flow sensor and processor to install sensors on the main oil channel and branch oil channel of the engine through the installation mechanism to perform flow resistance test. , combine the positioning mechanism and rotary adjustment bolt to achieve precise positioning and stable installation.

Benefits of technology

The test of the flow resistance of the entire engine branch is realized, avoiding the inconvenience and safety hazards of oil passage changes and hole drilling, and providing a simple and safe test method, which can obtain the real data of the flow of each engine oil passage and guide the optimization of engine performance.

Abstract

The present invention discloses an engine flow resistance test device and a test method, including an ultrasonic flow sensor, a mounting mechanism for mounting the ultrasonic flow sensor on the engine, a processor for processing and collecting information, and a display. The ultrasonic flow sensor is connected to the processor via a data line I, and the processor is connected to the display via a data line II. The mounting mechanism includes a mounting bracket, a sensor mounting chamber, and a positioning mechanism. The sensor mounting chamber is connected to the mounting bracket, the ultrasonic flow sensor is mounted in the sensor mounting chamber, and the positioning mechanism is arranged on the mounting bracket. A track is provided on the mounting bracket, and the mounting chamber I is slidably connected to the track, so that the entire sensor mounting chamber can move along the track, and the ultrasonic flow sensor can be fine-tuned in a horizontal plane. By using the test device and the test method of the present invention to test the flow of each oil channel of the engine, the real data and performance of the flow resistance (i.e., fuel consumption) of each oil channel of the engine can be essentially understood.
