FourStroke SingleCylinder Engine Model for Teaching and Demonstration Overview This assembled engine model clearly demonstrates the structure and working principles of a fourstroke singlecylinder engine. Made from plastic and metal components, the model is compact and ready to use out of the box for classroom demonstrations, handson learning, and technical training. Key benefits Clear visual demonstration of intake, compression, power, and exhaust strokes to help students and trainees understand internal combustion engine operation. Ready to use and portable design simplifies setup and classroom management. Dual operation options allow manual operation or connection to a power source for consistent demonstrations. Durable mix of plastic and metal parts balances visibility of moving components with longterm use. Battery powered operation uses two 1.5V AA batteries (not included), enabling demonstrations without external wiring when preferred. Specifications Material: Plastic and metal Power: 2 x 1.5V AA batteries required, not included Base length: approx. 17 cm / 6.69 inch Width: approx. 11 cm / 4.33 inch Height: approx. 30.5 cm / 12 inch Weight: approx. 766 g Package includes: 1 engine model, fully assembled How it solves common teaching needs Makes abstract engine cycles tangible by showing moving parts and timing relationships. Reduces preparation time with a preassembled model that can be used immediately. Supports varied demonstration styles by allowing hand cranking or powered operation for repeatable results. Use scenarios Classroom demonstration in junior or school physics to illustrate the fourstroke cycle and basic mechanical components. Technical training or vocational workshops where students practice identifying parts and observing timing and valve action. STEM or hobby projects where a compact, working model is needed to explain engine principles during presentations or science fairs. What stands out Fully assembled and compact for easy storage and transport. Built with visible moving parts to reinforce learning through observation. Dual operation modes for flexible demonstration approaches. This engine model is a practical teaching tool for educators, trainers, and hobbyists who need a reliable, easy to use visual aid to explain the fundamentals of a fourstroke singlecylinder engine.
