Society relies on IC engines for transportation, commerce and power generation. ICEs power the 600 million passenger cars and other vehicles on our roads today. Moreover 70% of the roughly 86 million barrels of crude oil consumed daily worldwide is used in IC engines for transportation resulting in 37 billion tons of CO2 (6 tons each for each person in the world) from fossil fuels/yr, plus other emissions, including nitric oxides (NOx) and particulates (soot). As CO2 emissions are linked to fuel efficiency contributes to Green House Gases (GHG), implicated in climate change drastic reductions in fuel usage are required to make appreciable changes in GHG. Nowadays governments are imposing stringent vehicle emissions regulations pushing engine developers to big challenges towards modern engine technologies. This course has the objective to provide students insight in new engine technologies, green fuels and emission after treatment systems to improve efficiency of gasoline and diesels and reduce emissions.
- SUBJECT 1: Principles of operation of modern engines and combustion in Otto and diesel engines.
- SUBJECT 2: Thermodynamic and gas dynamic study of piston engines: theoretical cycles of normally aspirated engines, actual circuit, pressure waves in the intake and exhaust of piston engines, heat transfer, indicators.
- SUBJECT 3: Friction, lubrication and mechanical efficiency.
- SUBJECT 4: Fuels: their properties and the criteria for assessing fuels. Why green fuels? EU targets, CO2 emission, including heavy duty vehicles in and outside Europe.
- SUBJECT 5: Biodiesel and fuels in liquid form, hydrogen and fuel cells, LPG, CNG, LNG. Emission standards for EU, US and Asia.
- SUBJECT 6: Second generation biofuels, effect on diesel engines, effect of ethanol on the ICE.
- SUBJECT 7: Mechanisms of origin of exhaust components.
- SUBJECT 8: New technologies and exhaust gas treatment systems for gasoline and diesel engines.
- SUBJECT 9: Trends in engine technologies: downsizing, turbo charging, HCCI.
