Working miniature water cooled IC engine model made from brass and stainless steel. This compact desktop model demonstrates the structure and motion of a real internal combustion engine while offering an attractive metal finish and durable construction. Key benefits Real working model: Operates as an internal combustion, water cooled engine so you can see and feel how components move in a functioning machine. Clear, handson learning: Ideal for visualizing engine cycles, cooling systems, and mechanical linkages. Attractive display and durable build: Brass and stainless steel parts give a classic retro look and longlasting performance. Features and important attributes Cooling and function: Water cooled design that reduces heat as the engine rotates, illustrating practical cooling principles. Materials: Brass and stainless steel construction for a metal, retro appearance and robust operation. Starting options: Two start methods offered — external force using an electric drill or manual starting by hand. Base and connections: Mounted on a wooden base with visible wiring and pipeline connections for setup and inspection. Power requirement: Requires one AA battery for ignition circuitry or related functions. Battery not included. Fuel and operation: Requires fuel to run; follow safe handling steps before operation. How to start 1. Inspect the wiring on the wooden base. 2. Connect the pipeline and fill the engine with fuel. 3. Install an AA battery if needed for ignition or circuit functions. Battery not included. 4. Turn the right side flywheel clockwise several turns to start, or use an electric drill for external starting. Refer to the included instruction sheet for full details. Safety notes Suitable for ages 16 and older only. Be careful when adding fuel and during operation. Do not touch the engine surface while running to avoid burns. Practical use scenarios Educational demonstration: Use in classrooms or workshops to show how an internal combustion engine and water cooling work in real time. Desk model for hobbyists: Display on a desk or shelf as a working conversation piece and mechanical toy. Gift for model enthusiasts: A handson present for collectors and anyone interested in engines and mechanical models. This model combines authentic mechanical motion, an educational focus, and a retro metal appearance to provide a practical and engaging miniature engine experience.
