Petrol Engine, Four Stroke

Demonstration Engine Models This Series Of Engine Models Illustrates Theory Of Operation And Other Functiolity Aspects Of The Principle Types Of Interl Combustion Engine. The Engines Shown Here Are Sections Cut For Clear Observation And Understanding Of Their Functioning By Viewing All Moving Parts Clearly. All The Models Are Made Of Cast Alloy And Are Mounted On Stable Base. These Models Are Not Functiol In True Sense But All The Working Parts Moves In Correct Relationship To One Another. Wherever Possible, The Models Are Provided With Printed Diagram Of The Engine With A Key Depicting Critical Components. Represents A Typical Air Cooled, Side-Valve, Four Stroke Petrol Engine With The Operation Of The Valves Clearly Evident. Cam Operated Inlet And Exhaust Valves Being Driven By A Gear Train From Rear Of The Main Crank. As With The Two-Stroke Model, Spark Plug Simulated Through A Small Lamp To Indicate The Firing Point. A Pair Of 4Mm Socket Termil For Electrical Supply. Cross-Section Of Carburetor Is Also Shown. (Mounted On Plastic Base)
