A clear glass display case encloses a cutaway model of a four-cylinder internal combustion engine, showcasing its internal workings. The engine model is primarily silver and green, with orange and blue accents highlighting the cylinder heads and valves. Four pistons are visible within their cylinders, connected to a crankshaft at the bottom. Above the cylinders, a complex arrangement of valves and springs is visible. In front of the display case, two informational cards are placed on a wooden surface. One card is a diagram with labels in French, and the other is a larger card with text in both French and English describing "The four-beat valve" and its function in the engine's operation. A person's shoulder and arm are visible on the right side of the frame, suggesting they are standing near the display. In the background, a blurred figure of a person is visible through a reflective surface, possibly a window or another glass partition. The overall environment appears to be a museum or exhibition space, with wooden flooring and walls.
