AI Technical Summary

Technical Problem

The high integration of the throttle valve in existing aero-piston engines leads to complex installation procedures, requiring assembly before testing. Field maintenance relies on experience to diagnose faults, lacks portable testing devices, and the components are easily damaged.

Method used

A test tool was designed, comprising a power supply module, an RS232 communication module, a four-channel sensor signal conditioning module, a two-channel motor drive module, a microcontroller module, and a quick-release onboard connector. It achieves power supply and communication through a USB Type-C interface, supports the detection of throttle position, temperature, and fuel injectors, uses a PID algorithm to control the throttle opening, and is equipped with a host computer interface for self-testing and fault diagnosis.

Benefits of technology

It enables portable testing and maintenance of throttle bodies, reduces the learning cost for assembly workers, improves assembly efficiency, supports field testing, simplifies break-in and durability testing, and improves fault location and maintenance efficiency.
