About this topic

This topic covers the demonstration of engine operation including describing internal combustion engines, examining main parts (piston, valves, cylinder head, cylinder, crankshaft, spark plug, connecting rod, cam shaft, injector nozzles), and relating parts to their functions. You will compare petrol and diesel engines and demonstrate two-stroke and four-stroke engine operations using models. These technical skills are essential for ECZ examinations and competence-based learning in farm mechanization.
