Course Contents | Four stroke cycle: SI engines and CI engines theory and operation Two stroke cycle: Theory and operation Engine output and efficiency: torque, brake power, friction power, indicated power Performance characteristics: speed, fuel consumption, volumetric efficiency, thermal efficiency, exhaust emissions, brake power, performance maps Factors influencing performance: size of cylinder, speed, load, ignition timing, compression ratio, air-fuel ratio, fuel injection, engine cooling, supercharging Real cycles and the air standard cycle: air standard cycles, fuel-air cycles, actual cycles and their losses Properties of fuels and combustion process: fuels for SI engines, knock rating of SI engines, Octane number requirement, Diesel fuels, Cetane number requirement, combustion process and flame development Alternative forms of IC engines: the Wankel rotary combustion engine, the variable compression ratio engine Developments in IC engines: fuel injection, supercharging Laboratory Work: Individual or small group experiments performed with the use of common vehicle engines and or single cylinder engines under certain loading conditions will be investigated. These results will be compared with engines manufacturer specifications and/or theoretical performance data. A selection from the following experiments is performed during the course: Air and fuel consumption in ICE and estimation of the volumetric efficiency and air-fuel ratio. Measurements of cylinder pressure history of ICE and construction of p-V and p-? engine diagrams Measurements of brake power and indicated power and estimation of the mechanical efficiency and thermal efficiency of an ICE Cylinder pressure and torque measurements of an ICE and construction of performance graphs and consumption loop Emissions measurements of a SI ICE engine Emissions measurements of a Diesel ICE engine Demonstration of dynamometer for ICE of light vehicles | ||||||||||
