Acquiring basic knowledge of IC engine's influence on environment. Knowledge of pollutants origin in exhaust of IC engines and the ways of their reduction. Understanding of legal obligations and emission standards. Pollution by hybrid and electric vehicles and their impact on the natural environment. Vehicles with zero exhaust emissions. Acquiring basic knowledge of noise sources in IC engines and the methods of noise reduction. Construction of an after-treatment system for exhaust gases.

Understanding the influence of human activities on environment, especially of harmful ones. Knowledge of pollutants formation chemistry, the greenhouse gases effects on global climate change, and noise of IC engines. Ability to apply solutions for pollutants and noise reduction.

1. Impact of IC engines on environment - general view (pollutants in exhaust, emission of greenhouse gases, engine noise). 2. Chemistry of pollutants formation in exhaust emissions of spark-ignition and compression-ignition engines, and the ways of their reduction. 3. Law regulations of the engine exhaust pollutants emissions. 4. NEDC (New European Driving Cycle) test and new WLTP (Wordwide Harmonised Light Vehicle Test Procedure )test. The purpose of the WLTP lab test and the way it works. 5. Greenhouse gases emission and their impact on global warming. 6. Engine noise, sources, standards, ways of reduction. 7. Engine exhaust emission regulations. 8. Alternative power system emission and electric-powered vehicles emission. 9.Impact of engine design on pollutants emissions and engine noise. 10.Construction solutions for the after-treatment system of exhaust gases, the principle of operation and type.

a) Classroom sessions: 1. Numerical examples. 2. Review and analysis of in-cylinder and after-treatment solutions for pollutant exhaust gases reduction: EGR, three-way catalyst, catalyst after-treatment of diesel engine exhaust emission. 3. Review and analysis of engine design solutions for engine noise reduction. b) Laboratory sessions: 1. Measurements of engine exhaust emissions with and without EGR.

Mandatory: passed exam Еngine Working Processes.
