This 4-stroke, 4-cylinder inline engine includes advanced components such as a turbo-supercharger, common rail direct injection system with electro-injectors, and a high-pressure pump capable of reaching 1,350 bar. It operates at a reduced speed of 220V (110V) for clear observation of mechanical functions, including a complete lubrication system with a gear pump and cartridge filter, as well as a cooling circuit with a water/oil exchanger. The engine’s internal parts are meticulously sectioned and painted for educational clarity, making it an invaluable tool for technical training.
