4 cylinder diesel engine cutaway is an electrically driven training unit designed for automotive education. It features a 4-stroke inline-4 engine with indirect injection, equipped with a Bosch VE-type rotary injection pump, overhead camshaft (OHC), and toothed belt-driven timing system. The model includes a thermostatic valve, alternator, and a water-cooling system. The engine runs on 220V (110V US) electric power at reduced speed for safe observation of internal mechanical movements. All mechanical systems, including lubrication, injection, and cooling circuits, are sectioned, color-coded, and surface-treated for extended durability in classroom environments.
