A model of four stroke water - cooled diesel engine ..
This is of the chain-driven overhead camshaft type and all functional components like camshaft, rock - arms,. tappets etc. are clearly demonstrated. The functioning of fuel injection system is also represented. Ignition is shown by means of a miniature bulb. Mounted on base.
Represents a typical air cooled, side-valve four-stroke petrol engine with the operation of the valves clearly evident, cams being driven by a gear train from rear of the main crank. As with the two-stroke model, simulated spark plug uses a small lamp to indicate the firing point. Screw terminals are provided for connection to 3 Volts battery. Cross-section of carburetter is shown. Mounted on base
