Construction and Design
The Section Model Of Four-Stroke Diesel Engine Torquemaster-37 is built as a 4-stroke diesel engine with 100 cc displacement and 6 hp power rating. The engine features a camshaft located in the crankcase with overhead valves for efficient operation. Indirect injection is used with a cam operated jerk pump, diaphragm injection nozzle, pre-chamber, and preheating glow plug. An oil pump provides lubrication, and a complete cooling system with distribution circuit is included. The model includes an RPM regulator, carburetor, air filter, silencer, and fuel tank. A 3-volt bulb shows the firing point of the engine, glowing at the correct point in the cycle through an electrical contact system. A small bulb lights up during the expansion phase to simulate the active stage of the cycle. The cutaway model is professionally painted with different colours to differentiate various parts, cross-sections, lubricating circuits, fuel system, and cooling system, with many parts chromium plated and galvanized for durability. Operation is manual through a crank handle.
