4 Stroke Diesel Engine Sectional Working Model

Demonstration engine model is mounted on metal base with printed diagram. Ignition is shown by means of miniature bulb. Carburetor and fuel supply are sectioned. With a crank handle for manual operation.

The Stirling engine was invented by Robert Stirling, a Scottish minister, in 1816. A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work.

The model demonstrates the principle, operation. It is cutaway to show the internal constructional details. Unlike other engines the rotary piston engine avoids reciprocating parts. The power pistons an arch like triangular rotor which on rotating generates an epitrochoid. Mounted on metal base with printed diagrams.
