THE ONTARIO CURRICULUM, GRADES 9 AND 10 | Technological Education
SPECIFIC EXPECTATIONS
By the end of this course, students will:
A1.1 identify the function and describe the construction and operation of the major parts of an engine (e.g., piston, crankshaft, connecting rod, camshaft);
A1.2 explain how power is produced in the course of an engine cycle (e.g., four-stroke cycle, two-stroke cycle, rotary cycle);
A1.3 identify the function and describe the liquid or air pathways and maintenance requirements of various engine cooling systems;
A1.4 identify the function and describe the con- struction and maintenance requirements of an engine lubrication system;
A1.5 identify the function and describe the con- struction and maintenance requirements of an engine fuel system.
By the end of this course, students will:
A2.1 describe the various types of drivetrains (e.g., direct, gear to gear, gear and chain, continu- ously variable systems);
A2.2 identify the function and describe the operation of major drivetrain components (e.g., transmission, clutch, differential);
A2.3 describe the power flow from engine to final drive (e.g., engine to wheels, engine to propeller, engine to track) in various types of drivetrains.
By the end of this course, students will:
A3.1 identify and describe the function of various types of steering/control systems and their components (e.g., systems: rack and pinion, recirculating ball, fly-by-wire; components:
rack, pitman arm);
A3.2 identify and describe the function of various types of suspension systems and their compo- nents (e.g., systems: coil spring, leaf spring, tor- sion; components: coil, leaf, torsion bar);
A3.3 identify and describe the function of various types of brake systems and their components (e.g., systems: mechanical, hydraulic, electric, pneumatic; components: emergency cable, wheel cylinder, magnet, brake chamber);
A3.4 identify and describe the function of the electrical system and its components (e.g., battery, fuses, starter);
A3.5.identify and describe major body, hull, and/or fuselage system components
(e.g., fender, keel, fairing).
