- Engineering measurements: Identify importance of measurements in engineering design and manufacturing. Classify the types of errors in measurements and the sources of errors. Distinguish between units in metric and imperial system and show how the conversions between the two systems is performed. Show how the measurement of linear dimensions and line graduated instruments is accurately performed using: Machinist’s rule, vernier caliper, micrometer (mechanic & digital) and gauge blocks. Analyse the way measurement of angular dimensions is performed. This will include units, subdivisions, conversions, instruments and measuring methods (sine bar, sinus and tangent method, angle gauge blocks, bevel protractor, combination square) Understand the function and usage of comparative length-measuring instruments such the Dial indicator. Understand form measurement (i.e. perpendicularity, flatness, etc). Analysis of dimensional tolerances which will include basic size, deviation and tolerance for a shaft and a hole according to ISO system. Also classification of types of fit, features of dimensional relationships between mating parts (allowance, clearance, interference, limit dimensions etc) are going to be defined. Finally surface texture and properties are to be discussed and will included mainly surface roughness.
- Internal Combustion Engines: Analysis of main features and controls of internal combustion engines, including cooling system, lubrication system, valve train, crankshaft mechanism, etc. Disassembly and rebuilt of an engine with various measurements and calculations taken out of the internal components. Analysis of the Electronic fuel and ignition system with measurements to be taken off various sensors using a series of tools like fuel pressure gauge, multimeters and oscilloscopes. Understanding functions of electric system (alternator, battery and starter) and some measurements to be taken off using tools like ammeter, voltmeter, tester light and hydrometer.
- Gas Analyzer: Understanding the main pollutants associated with vehicle exhaust emission and using a gas analyzer to measure them in live engine using either petrol or diesel fuels.
- Visit to workshops of industry: Visit to modern workshops of local industry to observe and gain knowledge of facilities and work environment.
