Internal combustion engines – theory for the application of conventional and renewable fuels

• Calculate basic parameters that are important to characterize the operation of an engine and analyze the effect of varying them on the performance and fuel economy.
• Simulate engine operation through the use of ideal air cycle models, ideal air exchange models, fuel air processes with chemical equilibrium, as well as dynamic models of heat transfer and combustion.
• Use simple models to describe the combustion processes for convetional and sustainable fuels in spark ignition and compression ignition engines.
• Calculate the friction for selected engine components and for the entire engine.
• Calculate the operating conditions for pressure charging machinery, such as compressors and turbocharges, and determine the effect of pressure charging on the performance and fuel economy of engines.
• Calculate the consequences of using different conventional and renewable fuels on the performance and economy of engines, as well as the dimensions for fuel systems for spark ignition and compression ignition engines.
• Calculate the relationship between fuel air ratio and exhaust emissions for different conventional and sustainable fuels, and calculate the emissions of air pollutants on the basis of engine output or the characteristics of a vehicle.
• Evaluate which fuels can be relevant in future applications of combustion engines
