Description
Content:
The module will develop a good understanding of the thermodynamic, design and operating principles of diesel engines including four- and two-stroke naturally aspirated and turbocharged units. Students will gain an appreciation of diesel engine environmental pollutants and their mitigation.
Although many students will have studied thermodynamics material (i.e. basic Carnot, Rankine Cycle) at undergraduate level, the module is designed to cover more practical aspects on modern aspects of power generation and propulsion cycles system design and evaluation, as well as additional topics on sustainable fuels and pollutants.
The recent developments in diesel engine systems are discussed is some detail. The impact of diesel engines toxic emissions on the environment is explained and technologies to mitigate the emission of toxic pollutants are discussed. The importance of thermal efficiency in reducing CO2 emission to the atmosphere is emphasised.
A significant part of this module addresses the latest development and practice in modern combustion engines in the context of land, air and sea applications.
An understanding of concepts relevant to the discipline, some from outside engineering, and the ability to critically evaluate and apply them effectively is developed in the coursework element. Environmental pollution-restricting legislation for diesel engines is discussed at several points during the course.
Teaching Delivery:
Usually a 2-hour lecture per week.
Indicative Topics:
Topics covered in this module include:
- Internal combustion engines
- Fuels and combustion
Module Objectives:
Upon completion of this module students will be able to:
- Use basic thermodynamic cycles to identify the main variables affecting spark and compression ignition engine efficiency.
- Understand and describe the gas exchange and combustion processes in diesel engines.
- Describe basic models to represent various gas dynamic and thermodynamic processes in diesel engines
- Analyse the performance of two stroke diesel engines, including large displacement slow speed engines used for marine propulsion and stationary power generation.
- Analyse and evaluate the performance of naturally aspirated and turbocharged diesel engines, including the compressor and turbine power requirements and the enhancement in engine power output and efficiency
- Gain an appreciation of a wider range of topics on fuels and combustion in reciprocating engines via coursework and student presentations.
