Part II

Safety Precautions

The same as outline in Part 1.

Drawing

The following additional factors shall be taught by the sue of geometrical instruments, producing drawings in first and third angle projections, isometric and oblique pictorial projections.

Occupational Information

The following additional areas shall be given:

(a) Apprenticeship and technician program; and information regarding vocational training institutes.

(b) Employment opportunities in selected careers.

Tools

Specialized re-assembling tools, presses and hand tools.

Engine Power

(a) Petrol Engines: Basic operation of two-stroke and four-stroke petrol and diesel engines.

(b) Concepts of In-Take, Compression, Ignition Power and Exhaust Strokes

(c) Diesel Engines: Basic operation of the diesel engine; advantages and disadvantages of diesel engines as compared to petrol engines.

Power Transfer

Students should be able to:

(a) change clutches and gears;

(b) know the application of gear systems, transmission/differential. Differential (propeller shaft, rear axle and side gears, drive pinion, etc.).

(c) know the conversion of mechanical energy into electrical energy.

Hydraulics

Students should describe the application of and be able to do, simple calculations with reference to:

(a) Pascal's law in the hydraulics braking system, presses and jacks.

(b) Bernoulli's principle in carburetion (pressure difference effects).

(c) Concept of fluid power.

Drive Transfer and Brake System

The mechanisms listed below are dealt with, leaving out calculations with the exception in case of rpm ration with respect to wheel diameter in cases of linked wheels:

(a) flat belt drive,

(b) chain drive,

(c) piston and crank shaft,

(d) automatic transmission,

(e) universal joint,

(f) clutch,

(g) splines,

(h) drum brake, and

(i) disc brake.

Engine System

The students are expected to know the principles and operation of:

(a) fuel system,

(b) ignition (battery, switch, coil, spark plug, generator, etc.).

(c) cooling system.

Trouble Shooting

Students will study problems and complete corrective procedures with regards to:

(a) faulty ignition systems,

(b) faulty carburetion,

(c) faulty valve gaps,

(d) faulty brake systems.
