About this topic

This topic provides a mechanical foundation for understanding farm machinery. Learners will describe the principles of the internal combustion engine, examine and relate the functions of key components (piston, cylinder, crankshaft, valves, etc.), and compare two-stroke and four-stroke cycles as well as petrol and diesel engines. This technical knowledge is a core competence in the CBC's mechanization strand. It is crucial for ECZ examination questions that require labeling engine diagrams, explaining engine operation, and understanding the basic mechanics behind tractors and other motorized farm equipment.
