Mechanical and Automotive 10, A20, B20, A30, B30
Explain multi-cylinder engine construction and operation.
Indicators for this outcome
| (a) | Explain the construction and function of major engine sub-assemblies (e.g., cooling, exhaust, lubrication systems) in multi-cylinder engines. |
| (b) | Differentiate between common automotive engine configurations (e.g., inline, V-type and opposed). |
| (c) | Differentiate between common automotive valve train configurations (e.g., cam in block, single overhead camshaft and dual overhead camshaft) in multi-cylinder engines. |
| (d) | Describe how the events of combustion change with different fuel sources (e.g., diesel, varying octane gasoline and compressed natural gas [CNG]). |
| (e) | Compare the air flow of naturally aspirated and forced air (e.g., supercharged and turbocharged) engines. |
| (f) | Explain the purpose and operation of internal engine components (e.g., camshaft, crankshaft and pistons) and variations (e.g., cam lift, piston shape and ring design) of each component. |
| (g) | Define and determine engine measurements such as displacement, compression ratio and clearance. |
