Demonstrational Section Working Model of 4 Stroke Petrol Engine
A cut-section working model of a 4-stroke petrol engine to demonstrate valve timing and piston action.
Overview
The Demonstrational Section Working Model of the 4 Stroke Petrol Engine is a transparent or colour-coded cut-section model that visually displays all internal components and their sequenced operation. The model rotates slowly via an electric motor so students can clearly observe each of the four strokes: suction, compression, power, and exhaust, along with valve timing and ignition events. This model is ideal for classroom and lab demonstrations, providing a concrete visual understanding of engine kinematics, valve train operation, and the thermodynamic cycle of a spark-ignition engine before students proceed to performance testing on live engine test rigs.
