A. TRANSPORTATION TECHNOLOGY FUNDAMENTALS
OVERALL EXPECTATIONS
By the end of this course, students will:
A1. demonstrate an understanding of the fundamental principles of engines and their service, repair, and maintenance;
A2. demonstrate an understanding of basic electrical and electronic circuits and their components;
A3. identify the function and explain the operation of the major systems and components of vehicles,
aircraft, and/or watercraft;
A4. demonstrate accurate and appropriate use of technical and mathematical knowledge and skills in the study of transportation technology.
SPECIFIC EXPECTATIONS
A1. Understanding Engines
By the end of this course, students will:
A1.1 explain terminology describing internal combustion engines (e.g., top dead centre, over- head camshaft), cylinder configurations (e.g., V6, in-line), and types of measurement (e.g., bore, stroke, cylinder displacement) in terms of engine operation;
A1.2 describe the design and construction of various components of an internal combustion engine (e.g., camshafts, pistons, crankshafts, rotors, valves, turbines);
A1.3 describe the service procedures required to rebuild, repair, and maintain engines (e.g., use of correct torque procedures, use of plastigauge to check bearing clearance, use of feeler gauges and micrometers to check clearances, use of chemical compounds [sealants, thread-locking compounds]);
A1.4 explain the principles on which the opera- tion of fuel, lubrication, and coolant systems is based (e.g., fuel: volatility; lubrication: viscosity; coolant: heat transfer);
A1.5 explain how engine timing (e.g., ignition tim- ing, valve timing, mechanical fuel injection timing) is used to achieve optimal engine performance;
A1.6 describe the parts, operation, and care of a variety of precision measuring tools (e.g., micrometer, vernier caliper, torque wrench, dial indicator, bore gauge) and demonstrate proper use of these tools;
A1.7 describe common procedures for inspecting engine components for wear and faults (e.g., check cylinder for taper, check cylinder head for warpage) and demonstrate accurate use of these procedures.
By the end of this course, students will:
A2.1 describe the fundamental concepts and laws related to the flow of electricity (e.g., flow of electrons, magnetic fields, Ohm’s law, Kirchhoff’s laws) that underlie the electrical components and systems found in vehicles, craft, and powered equipment;
A2.2 define electrical units of measure (e.g., volts, amps, ohms) and demonstrate the ability to read wiring schematics (e.g., wire size and colour, symbols);
A2.3 define the fundamentals of electronic circuits and components (e.g., on-board computers, diodes, transistors, light-emitting diodes [LEDs]);
A2.4 explain the consequences of open, short, ground, and unintentional ground circuits (e.g., electrical surges, voltage drop, voltage spike);
A2.5 describe basic procedures involved in circuit repair (e.g., use of heat shrink, use of solder and solderless connections);
