This module introduces the learner to the fundamental concepts and practical applications of engineering science in automotive technology and is intended to suit students with no previous knowledge or experience of the topic matter. The relevant engineering science will include topics in both Heat Engines and Applied Mechanics. Through the use of bespoke class-notes learners will be helped to understand the scientific principles involved and their application in motor vehicles and transport in general. The student’s learning experience will be enhanced by providing practical demonstrations and facilitating experiments in our Automotive Science Laboratory.
