Welcome to the "Mastering the Science of Internal Combustion Engine Emission" course.Are you interested in understanding how engine emissions contribute to air pollution and how to control them? If so, this course is for you!In this course, you will learn about the various types of pollutants emitted by internal combustion engines, including carbon monoxide, nitrogen oxides, and hydrocarbons. You will also learn about the differences between gasoline and diesel engines, and how their emissions affect the environment.You will learn about the negative impacts of engine emissions on public health, including respiratory diseases like asthma and eye irritation. You will also learn about the contribution of engine emissions to acid rain and climate change.But it's not all bad news! This course will also provide you with strategies for reducing engine emissions and improving air quality. You will learn about different technologies and methods for controlling emissions, such as catalytic converters and exhaust gas recirculation systems. You will also learn about the importance of proper fuel consumption and maintenance to reduce emissions.Throughout the course, you will have the opportunity to apply your knowledge through interactive quizzes and hands-on exercises. You will also have access to a variety of learning resources, including video lectures, readings, and online simulations.Join us on this important journey as we explore the world of engine emissions and learn how to control them for a healthier, cleaner environment!COURSE OUTLINEAir Pollution due to IC EngineEuro Norms / European Emission Standards of IC Engine Emissions Classification of Engine Emissions (Exhaust and Non-Exhaust Emissions)Causes of Hydrocarbon EmissionIncomplete CombustionCrevice Volumes and Flow in CrevicesLeakage past the Exhaust ValvesValve OverlapDeposits on WallsOil on Combustion Chamber WallsType of Engine EmissionsHydrocarbon Emissions from SI and CI EngineCarbon Monoxide (CO) EmissionsOxides of Nitrogen (NOx) EmissionsPhotochemical SmogParticulates EmissionAldehydes and Lead EmissionOxides of Sulfur (SOx) EmissionsHow to Control IC Engine Emissions in the following ways.Modification in Engine Design & Operating ParametersCombustion Chamber Configuration Lower Compression RatioModified Induction SystemIgnition TimingReduced Valve OverlapEmissions Control by Exhaust Gas OxidationThermal ConvertersCatalytic ConvertersExhaust Manifold ReactorExhaust Gas RecirculationParticulate TrapsCrankcase BlowbyEmission Control by Modification of Fuels
