Learning Outcomes of the course unitBy the end of the course, the students should be able to:
  1. Explain the flow rate through valves and effects of valves lift and timing on volumetric efficiency. Describe the flow pattern related with the valves motion and positions. Analyse the inlet and exhaust valves opening overlap for various engine operating conditions. Assess the effects of manifold components characteristics on engine performance. Describe aspects for exhaust manifold design and exhaust gas recirculation strategies.
  2. Describe the various injection systems integrated with the inlet manifolds and inlet valves (carburetors, indirect injection systems) for SI engines. Explain the direct injection systems and injection strategies for SI and Diesel engines and assess their effects on the inducted charge and in-cylinder gas motion.
  3. Describe the general requirements for engine cooling via water or air cooling systems. Compare the differences between water or air cooling systems and identify the appropriate cooling systems for various engine applications. Describe the requirements and properties of the cooling agent and learn the characteristics and capacity of the cooling system components. Calculate engine heat transfer to the coolant and the cooling system components using heat transfer methodology.
  4. List the general requirements for lubrication of the various engine components. Describe the types of lubrication and explain where these types occur in engines. Describe the lubricant characteristics for various engine operating conditions. Describe piston and rings assembly and their functions in engine operation. Distinguish different piston types and geometries and explain the corresponding induced in-cylinder gas flow.
  5. Describe the different materials used for the cylinder block, engine head and pistons. Relate the imposed design constraints with the high temperatures taking place in engines. Describe the assembly of connecting rods, crankshaft and the distribution of power to auxiliary engine components. List the various mechanisms of camshafts and valves and explain their operation.
  6. Describe the single-phase and two-phase flow conservation equations and their coupling for simulation of the fuel injection and air/fuel mixture preparation and combustion process taking place is SI and Diesel engines. Analyse the burn rate and explain the heat release rate history estimated from CFD engine simulations. Simulate induction and spray processes with Computational Fluid Dynamics (CFD) code.
  7. Describe experimental measurement techniques and facilities for ICE engine measurements. Describe the engine test bed facilities used for ICE testing and characterization.
  8. Apply exhaust gas measurement techniques. Explain the oxygen and air/fuel ratio analysis, the exhaust gases composition, smoke and particulates emitted by SI and Diesel engines and explain the corresponding engine behaviour and performance with varying engine performance parameters.
