1. This training aid is used for understanding the structure and working principle of the five mechanisms and two systems, by regionally dissecting the air cylinder engine, then treating with different colors to visually demonstrate the structure and working principle of the internal parts. 2. Driven by AC220v variable-frequency and variable-speed motor, it is clearer in dynamic demonstration. 3. All the dissection parts are dust proof and need no oiling.
The following teaching and practicing items can be performed: 1. Knowledge of entire components of engine; 2. Knowledge of peripheral appurtenances of engine; 3. Knowledge of crank-link mechanism of engine; 4. Knowledge of valve mechanism of engine.
