The DOHC Petrol Engine Training Stand features a sectioned cutaway of a modern engine, providing full visibility of the crankshaft, pistons, connecting rods, camshafts, valves, rocker arms, timing chain, lubrication, and cooling system. Manual crank rotation allows learners to observe synchronized movement of all components, while the integrated auxiliary drive system—including belt, tensioner, pulleys, alternator, water pump, and AC compressor—demonstrates real-world operation. The trainer supports over 30 practical exercises, including belt removal, auxiliary component replacement, timing service, TDC setting, and camshaft alignment, making it an ideal hands-on tool for technical and vocational automotive education.
