ENGINEKITOR Transparent Cylinder Single-Cylinder 4-Stroke Engine Model – Full Metal Visible Internal Combustion Engine for STEM Learning, Teaching, and Collector Display

Experience the power of real mechanics with this visible-cylinder ethanol engine model. It features a transparent combustion chamber, precision-machined metal parts, and a functional ignition system that runs on alcohol fuel — perfect for STEM learning, mechanical demonstrations, and collector display.

🔧 Key Features

• Real 4-Stroke Cycle: Watch every stage of the engine’s cycle — intake, compression, combustion, and exhaust — through a fully transparent cylinder.
• Authentic Ignition and Operation: Fueled by ethanol for true combustion and realistic motion.
• Visible Water-Cooling System: Circulating loop for stable heat control and continuous operation.
• Educational Value: Demonstrates energy conversion and mechanical dynamics in an easy-to-understand visual form.
• Premium Build: CNC aluminum alloy, brass fittings, acrylic cylinder, and a solid wooden base for lasting quality and display appeal.

⚙️ Upgraded Design Highlights

1. Transparent combustion chamber window for real-time observation.
2. Visible circulating water-cooling channel for efficient heat dissipation.
3. Belt and gear synchronization system showcasing real mechanical transmission.
4. Offset cam and valve structure for authentic timing simulation.
5. Sealed bottom oil chamber to promote smooth lubrication.
6. Precision spark ignition system with stable performance.
7. Silver-contact power switch for safety and durability.
8. Quick water circulation with efficient thermal balance.

🧭 Startup Instructions

1. Install the spark plug, connect the ignition system, and attach the water-cooling tubes.
2. Check compression and ignition before fueling.
3. If the room temperature is below 25°C, preheat the cylinder with warm circulating water for 5 minutes.
4. Turn off the power, cover the air inlet, and rotate the flywheel clockwise until you see fuel enter the cylinder.
5. Turn on the power, set the throttle at about 70°, and spin the flywheel to start the engine.

Note: Difficulty starting in extreme temperatures is normal due to fuel characteristics. Repeat steps 4–5 if needed. For stronger performance, an upgraded carburetor or intake system can be used (recommended for experienced users only).

⚠️ Safety & Maintenance

• Do not touch moving gears, the flywheel, or exhaust pipe during operation.
• Avoid contact with high-voltage ignition components; ensure proper grounding to prevent electric shock.
• Do not run the engine for more than 2 minutes without water cooling.
• Minors must operate under adult supervision.

🎓 Educational & Display Value

This transparent ethanol-powered engine vividly demonstrates the mechanical structure and thermal principles of a real internal combustion engine. Ideal for students, educators, engineers, and collectors, it serves as a perfect visual aid for teaching thermodynamics, mechanics, and energy transformation.
