The aims of this unit are to:
* describe the technical requirements of a performance engine;
* illustrate practically and theoretically the demands placed on an engine when used in competition;
* demonstrate the importance of test procedures with regard to engine performance and longevity.
On completion of the unit the student should be able to:
* demonstrate a knowledge and understanding of the dynamic and thermal processes that occur during an internal combustion engine cycle with regard to the preparation, combustion and emission of the air/fuel mixture;
* understand the design requirements of competition engines for different motor sport disciplines;
* understand the performance limitations when modifying a production based engine for competition;
* demonstrate a detailed appreciation of the design of existing competition engines.
During the unit students should gain the following skills:
* rationalising engine design and modification within given constraints (T,A)
* interpreting regulations where they apply to engine design and modification (F)
* producing and comparing performance data using appropriate engine testing equipment (T,A)
* evaluating engine performance against given criteria (T,A)
* working with a range of engine designs and modifications (F)
* understanding the performance requirements of a competition engine and how they might be achieved (F,A).
This unit concentrates on:
* engine performance characteristics and boundaries to include petrol, diesel and alternative fuels;
* high performance road engine design criteria, to include legislation / emission requirements;
* competition engine design criteria, to include technical regulations and end use;
* cylinder head and valve train design;
* engine component design and testing;
* engine management systems with regard to fuel systems and combustion control;
* materials technology in engine design;
* the engine interface with the transmission and chassis as a component of the competition vehicle package;
* engine test and development procedures including simulation and dynamometer testing;
* life cycle of engine components.
