  It covers the following strands and sub-strands:

  • 4.0 Engines
    • 4.1 Introduction to Engines
      • Defining engine concepts, energy transformation principles, and daily applications
      • Identifying major structural parts of a single-cylinder engine model
      • Defining Top Dead Centre (TDC) and Bottom Dead Centre (BDC) piston limits
      • Explaining cylinder bore diameter, stroke length, cubic capacity, and horsepower
      • Measuring bore diameter and stroke length practically using vernier callipers and depth gauges
      • Calculating total engine displacement capacity mathematically using formulas
    • 4.2 Classifications of Engines
      • Outlining parameters used to classify internal combustion engines
      • Comparing internal versus external combustion processes and efficiencies
      • Categorizing engines by physical size and power output ratings (small, medium, large)
      • Comparing fuel types (petrol, diesel, alternative fuels) and ignition methods
      • Comparing air-cooled fin systems with liquid-cooled radiator circuits
      • Observing real-world engine classes during local power mechanics workshop visits
    • 4.3 Types of Engines
      • Comparing combustion engine cycles and working fluids in steam vs. gasoline engines
      • Describing single-cylinder vs. multi-cylinder engines and power delivery smoothness
      • Describing cylinder configurations (inline, V-type, rotary, opposed) and technical sketching
      • Explaining engine operating speed classifications (low, medium, high RPM)
      • Explaining four-stroke engine cycle principles (induction, compression, power, exhaust) and valve timing
      • Explaining two-stroke engine cycle principles (transfer and exhaust port operations)
      • Comparing two-stroke and four-stroke fuel efficiency, emissions, and machinery applications
    • 4.4 Engine Components
      • Categorizing stationary structural components and moving engine mechanisms
      • Inspecting cylinder block, cylinder head, crankcase, oil sump, and rocker cover construction
      • Inspecting moving parts: piston assembly, connecting rod, gudgeon pin, crankshaft, camshaft, and valves
      • Sketching and labeling stationary and moving internal combustion engine components
      • Measuring cylinder bore wear (taper/ovality), crankshaft journals, and piston ring end gaps against service limits
