This unit will build on learners’ understanding of polytropic expansion/compression processes, the first law of thermodynamics and the concepts of closed and open thermodynamic systems. Learners are then introduced to the second law of thermodynamics and its application in the measurement and evaluation of internal combustion engine performance. This is followed by measurement and evaluation of air compressor performance. Finally, learners will develop an understanding of the layout and operation of steam and gas turbine power plants.

This unit will provide learners with an advanced understanding of vehicle fault diagnosis and will
enhance their ability to diagnose faults and select appropriate equipment from given data in a
number of disciplines. They will also learn about techniques of measurement when determining
the performance of a vehicle system.
Learning outcome 1 will enable learners to increase their knowledge of fault diagnostic
techniques and the interpretation of fault symptoms. Learning outcome 2 considers the principles
of measurement and testing to determine the performance of vehicle systems. Learning outcome
3 is concerned with the evaluation and presentation of test results and the production of a fault
location guide for a given vehicle.

This unit will develop learners’ knowledge of electronic power steering systems and active
suspension control systems. Learners are then introduced to anti-locking braking systems,
traction control systems and integrated dynamic stability control systems.
Learning outcome 3 is concerned with advanced central locking and security systems, integrated
heating and air conditioning and driver and passenger impact protection. Finally learners will
carry out and record the results of practical fault diagnosis tests on advanced vehicle power
steering, suspension and central body systems. This will also require them to interpret the results
from the fault diagnosis tests and evaluate the serviceability of a system and its components.

This unit will develop learners’ understanding of complex loading systems and will provide an introduction to the concept of volumetric strain and the relationship between elastic constants. The expressions derived for linear and volumetric strain then form a basis for determining dimensional changes in loaded cylinders. The unit will build upon learners’ existing knowledge of the relationship between the distribution of shear force and bending moment in loaded beams, to include the relationship between bending moment, slope and deflection. Learners will analyse the use of mechanical power transmission systems, both individually and in the combinations that are used in practical situations. Learners’ knowledge of rotating system elements is further extended through an investigation of the dynamic characteristics of the slidercrank and four-bar linkage. The balancing of rotating systems is also investigated, together with the determination of flywheel mass and size to give sufficiently smooth operating conditions
