Secondary revision · Agriculture Science Form 4
Engines
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.

Outcomes
If you passGreat work! You have grasped the fundamental workings of internal combustion engines, providing a solid technical base for questions on farm mechanization in the ECZ exam.
If you don't pass yetFocus on the names and functions of the main engine parts. Practice drawing and labeling a simple engine diagram and understand the sequence of events in a four-stroke cycle.
