Two-Stroke Engine Cutaway – Technical Teaching Model – 1960s–1970s – Industrial Demonstrator
A vintage mechanical teaching model demonstrating the working principle of a two-stroke internal combustion engine, manufactured in the mid-20th century for use in technical schools and engineering institutes.

This cast-metal display features a cutaway cylinder, piston, connecting rod and crank assembly, allowing students to observe the full cycle of a two-stroke engine. When the crank is rotated, the piston moves inside the cylinder, clearly illustrating compression, scavenging and exhaust processes.

The model is finished in industrial blue and aluminium, typical for instructional aids from the period. Its simplified, clean construction makes it ideal not only as a learning tool, but also as a striking decorative object for workshops, studios, or collectors of mechanical artefacts.
