Optimal exergy-based control of internal combustion engines

Transient combustion control of internal combustion engines

This thesis addresses the problem of combustion control for automotive engines. A method is proposed to complement existing controllers, which use lookup tables based on steady-state operation. During transients, the new control method adjusts fast control variables (ignition or injection time) to compensate for deviations in the cylinder initial conditions from their optimal values due to the ...

Model and Observer Based Control of Internal Combustion Engines

Much progress has been made in the area of electronic engine controls since their introduction in the 1980’s. This progress has included significant improvements in fuel economy and emissions reductions. Nevertheless current ECU’s (Engine Control Units) are much less advanced than those which can be found in the literature. These advanced controllers are most often model based and include nonli...

Ethanol Internal Combustion Engines

Ethanol Internal Combustion Engines HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – The use of biofuels (e.g. bio-ethanol and biodiesel) in the transport sector can save significant amounts of fossil fuels and greenhouse gas (GHG) emissions. Internal combustion engines (ICEs) can run on bio-ethanol manufactured from biomass or waste through biochemical processes. Agricultural feedstock such as sugar...
