Technical Specifications
| Specification | Value |
|---|---|
| Model type | Sectional cut-away |
| Engine type | Four-stroke, spark ignition (Otto cycle) |
| Operation | Manual hand crank |
| Ignition display | Miniature light timed to spark plug firing |
| Parts shown | Piston, connecting rod, crankshaft, cams, valves |
How It Is Used
Turning the handle takes the engine through suction, compression, power and exhaust. Students see the inlet and exhaust valves open in turn, the piston compress the charge, and the light flash at the spark plug to start the power stroke, which makes valve timing easy to explain.
