Title:I.C. ENGINE - PRINCIPLES OF THE INTERNAL COMBUSTION ENGINE [Main Title]
Film Number:AMY 223
Summary: Detailed instructional film focusing on the principes of the internal combustion engine.
Description: Reel 1: “In 1862 the first 4 stroke internal combustion engine was made. Since then, civilization has become dependent upon its applications.” Description of the workings of a IC engine. “Heat and Work” - basic demos of how heat expands air. “The 4-Stroke Cycle” - animated diagram explaining how 4-stroke engine works.
Reel 2: “Elements of the 4-Stroke Engine” Cutaway model of engine used to demonstrate workings of engine and valves. Workings of carburettor. “Mechanical Construction” - 9 cylinder aero engine cutaway model used for demonstration of the parts of the engine working in unison
Reel 3: “Valve Timing” - as title, “Valve Timing Effect of The Weight of the Mixture”, mixture lag explained. Valve timing explained. “Valve Operation Time-Lag”, “Valve Timing – Inlet Opens”, “Inlet Closes”, “Exhaust Opens”, “Exhaust Closes”, “Circular Timing Diagram”,
Reel 4: “Carburation” - MkI Hurricane ground running. Basic carburettor explained. “The Float Chamber” - explanation of the workings of the float chamber. “The Choke Tube” - Venturi Effect demonstrated on an induction pipe.
