Idle air valve dissected model

Product Overview:

This product is a cross-sectional anatomical teaching model developed for teaching and practical training in automotive engine idle speed control. It uses the same idle speed valve structure as the real vehicle, machined at a 1:1 scale, fully preserving the internal mechanical structure, moving parts, and air passages. It can intuitively demonstrate the entire process of idle air regulation, stepper motor drive, and valve opening and closing. It is suitable for practical training in engine electronic control systems in vocational schools, technical colleges, and training institutions.

Features:

1. 1:1 Real Vehicle Structure Reproduction: Made using a universal stepper motor-type idle speed valve prototype, the installation dimensions and internal structure are consistent with the real vehicle, making the teaching scenario highly similar to actual maintenance practice.

2. Full Cross-Sectional Visibility Design: The housing is longitudinally cut with windows, intuitively displaying the internal structure of the stepper motor, gear set, valve stem, valve core, bypass air passages, etc., allowing for clear viewing of the working path without disassembly.

3. Dynamic Demonstration of Principles:

4. Supports manual push-pull valve core and external power supply drive, clearly demonstrating:
Stepper motor forward and reverse rotation driving valve core extension and retraction
By changes in bypass air passage opening
Correspondence between opening and idle speed

5. Observable and Testable Components: Key components are exposed and visible, allowing for teaching and explanation of typical failure modes such as wear, jamming, carbon buildup, and gear damage, facilitating fault phenomenon recognition and analysis.

6. Compatible with Electronic Control Training Platforms:
Can be connected to engine electronic control training platforms for signal power supply and action simulation, supporting idle speed control circuit and actuator testing training.

7. Durable, Teaching-Grade Structure: Smoothly polished cut surfaces, reinforced key components, drop-proof, wear-resistant, and corrosion-resistant, suitable for long-term repeated teaching demonstrations and practical training.

8. Intuitive and Easy-to-Understand Teaching: The logic of "electronic control signal → mechanical action → air flow → idle speed" is presented completely, significantly reducing the difficulty of teaching idle speed control systems.
