Engine, Diesel, 4 Stroke
Engine, Diesel, 4 Stroke (Product Code: SLE/PHY/170) is a hand-cranked working model used to demonstrate how a four-stroke diesel engine operates in physics and automotive training classrooms. Turning the main shaft by hand drives the crankshaft, cam, valves, piston and fuel pump through every stage of diesel firing, and a 6 V supply lights the ignition light and glow plug. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the 4 Stroke Diesel Engine Model Used For?
Teachers crank the model slowly to walk students through intake, compression, power and exhaust, pointing out how the cam, push rods and rocker arms open each valve at the right moment and how the injection pump and nozzle deliver fuel. Because a diesel engine ignites fuel by the heat of compression rather than a spark, the model is also a good way to explain why a glow plug helps with cold starts.
Its long list of identifiable parts makes it a ready labelling exercise for mechanics lab equipment in India used in physics, ITI and automotive courses. Crank gently without forcing the mechanism, keep moving parts free of dust, and switch off the 6 V supply after the lesson.
What to Specify When Ordering
- Whether you need a 6 V power supply for the ignition light and glow plug, or already have one.
- The number of models required for demonstration or group work.
- Any parts your syllabus asks students to identify, so we can check them against the list above.
