  "brief": "The canvas displays a dynamic, cross-sectional cutaway of a running internal combustion engine. Pistons are shown moving up and down inside their respective cylinders, powered by the rotation of the crankshaft. The visualization highlights the timing mechanism: the intake and exhaust valves are clearly visible and open and close with precise timing, demonstrating their relationship to the piston's position. The overall composition uses mechanical shapes and colored elements to illustrate the continuous, cyclical process of combustion.",

  "statement": "This sketch visualizes a dynamic, cross-sectional cutaway of a running internal combustion engine. It shows pistons moving up and down within their cylinders, driven by the rotation of a crankshaft. The timing mechanism is highlighted through clearly visible intake and exhaust valves that open and close in precise synchronization with the piston's position. Mechanical shapes and colored elements illustrate the continuous, cyclical process of combustion, emphasizing how the engine operates as a coordinated system of moving parts.",
