4-stroke, 4-cylinder petrol (gasoline) engine with a 2000 cm³ displacement and a twin overhead camshaft driven by a toothed belt. It includes a 5-speed gearbox with reverse, a differential with a hypoid crown wheel and pinion, and a dual braking circuit with front disc and rear drum brakes. The engine utilizes electronic ignition and operates electrically at 220 volts (110V US), running at reduced speed to facilitate detailed observation of its mechanical functions. The cutaway design, with chromium-plated and galvanized components, reveals critical systems including lubrication, fuel, and cooling for comprehensive educational use.
