Module information on this degree can be found below, separated by year of study.

The module information below applies for the current academic year. The academic year runs from August to July; the 'current year' switches over at the end of July.

Students select optional courses subject to rules specified in the Mechanical Engineering Student Handbook,  for example at most three Design and Business courses. Please note that numbers are limited on some optional courses and selection criteria will apply.

Future Clean Transport Technology

Module aims

 To provide:

·      A basic understanding of the design features of reciprocating internal combustion engines and the underlying engineering science, with particular reference to the fluid flow, thermodynamics and combustion processes of spark- and compression-ignition engines.

·      An awareness of the means by which the need for reduced CO2 and pollutant emissions is met.

·      A basic understanding of the design features of hybrid, electric and fuel cell powered vehicles and the underlying engineering science, with particular reference to system design of battery packs and fuel cell systems.

·      A basic understanding of how the technologies compare to each other and how they fit into the bigger picture of the whole transport/energy system.

A practical, industrial context for the above knowledge through talks from visiting industry experts.

Learning outcomes

 On successfully completing this module, students will be able to:

  • Discuss, using appropriate technical terminology, the drivers for development in vehicle propulsion and the extent to which available technologies provide appropriate solutions
  • Construct simple physical and computational models of a selection of processes occurring in conventional and advanced reciprocating IC engines, including combustion
  • Assess the likely future of the internal combustion engine in the land transport sector
  • Demonstrate organisational, information gathering, problem solving and information technology skills within small group projects
