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

It is used to study the motion under the effect of gravity of two mass systems connected through a lightweight cord, one on either side of a simple pulley. This apparatus comprises 2 long metals rods, one rod having a well-balanced 10cm pulley mounted at its one end on near-frictionless bearings and threads at other end for attaching it to the second rod to get a total working length of 245cm. A scale 0- 245cm continues from the top of rod with pulley to the bottom of the second rod.
Complete set includes electromagnetic release arrangement, set of 2 pairs of masses, Loading Masses – 1g, 2g, 1g, table/ring brackets, wall mounting clamps and lightweight cord..
