Pre-requisite Courses and Assumed Knowledge and Capabilities
This course builds on your studies in thermodynamics and fluid mechanics to give you fundamental knowledge and skills required of practicing engineers in the discipline of Vehicle Power Systems. This course provides you with the understanding of the fundamentals of piston engine performance analysis, dynamics of the two and four stoke engine, and elements of its design.
Under these major headings, the course will cover the following general topics:
- Piston engine classification, Engine indicated work, pressure and indicated power. Mean effective pressure, brake effective power
- Combustion and efficiencies; knock and its detection, consequences and elimination, effect of fuels, additives and octane ratings Engine performance characteristic and engine operating regimes:-Steady, transient and unsteady; Continuous and intermittent regimes.
- Engine load and speed characteristics. Fuel air ratios: Lambda/equivalency ratio influence on engine performance
- Super- and turbo-charging the engine: Impact of super and turbo-charging the engine. Arrangement of supercharger and turbo-chargers. Fuel injection in spark ignition and compression ignition engines.
- Principles of operation ignition systems: ignition timing
- Properties of exhaust gases: pollution and emission control treatments
- Engine dynamics, design analysis, principal dimensional analysis and specific parameters.
