1. 1. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

   University essay from Linköpings universitet/Fordonssystem

   Author : Jonatan Gustafsson; [2021]
   Keywords : MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

   Abstract : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. READ MORE

3. 2. A GENeric Internal Combustion Engine model : LiU-Genie

   University essay from Linköpings universitet/Fordonssystem

   Author : Oskar Lind Jonsson; [2021]
   Keywords : ;

   Abstract : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. READ MORE

4. 3. Impact of Pressure Pulsations on Diesel Air Path Control and Compensation Measures

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : NISHANT DHANORE; [2019]
   Keywords : ;

   Abstract : Stricter pollution norms have led to increased efforts to achieve lower emissions. Exhaust Gas Re-circulation (EGR) is a well known measure to reduce NOx internally in the engine. In order to achieve better performance of an engine in terms of emissions it is very essential to control the flow of exhaust gases through EGR valve. READ MORE

5. 4. The Miller Cycle on Single-Cylinder and Serial Configurations of a Heavy-Duty Engine

   University essay from KTH/Förbränningsmotorteknik

   Author : Varun Venkataraman; [2018]
   Keywords : Two-stage turbocharging; modelling and simulation; GT-Power; performance; Miller cycle; heavy-duty diesel engine; Tvåstegs turboladdning; modellering och simulering; GT-Power; prestanda; Miller-cykel; lastbils dieselmotor;

   Abstract : I jämförelse med sina föregångare, har moderna lastbilsmotorer genomgått en betydandeutveckling och har utvecklats till effektiva kraftmaskiner med låga utsläpp genom införandet avavancerade avgasbehandlingssystem. Trots att de framsteg som gjorts under utvecklingen av lastbilsmotorer har varit betydande, så framhäver de framtida förväntningarna vad gällerprestanda, bränsleförbrukning och emissioner behovet av snabba samt storskaliga förbättringar av dessa parametrar för att förbränningsmotorn ska fortsätta att vara konkurrenskraftig och hållbar.

6. 5. Compressible Flow Modeling with Combustion Engine Applications

   University essay from Linköpings universitet/Fordonssystem

   Author : Carl Vilhelmsson; [2017]
   Keywords : Compressible; Flow; Modeling; Combustion; Engine; Throttle; EGR; Wastegate; Valves; Gas;

   Abstract : The high demands on low fuel consumption and low emissions on the combustion engines of both today, and the future, is highly dependent on advanced control systems in order to fulfill these demands. The control systems and strategies are based on models which describe the physical system. READ MORE
