1. 1. Come Fly with Me (Sustainably) : Pathways to Sustainable General Aviation and Private Pilot Training

   University essay from Högskolan i Gävle/Miljövetenskap

   Author : Michael Stiebe; [2022]
   Keywords : General Aviation; Sustainable Aviation; Sustainable Development; Electric Aviation; Noise Pollution; Leaded Fuel; AVGAS 100LL; Tetraethyl Lead Phaseout; Pilot Training; Recreational Aviation; Switzerland;

   Abstract : Whereas commercial aviation is attempting to achieve the reduction of its substantial carbon footprint, general aviation’s (GA) climate change contribution is negligibly small, which is why the sector is facing other sustainability challenges mainly entailing the operation of dated technology and aircraft, increasing regulatory constraints, rising costs, noise emissions, and popular discontent, as well as remaining the last mobility sector in the world to still use leaded fuels. Throughout recent years, there have been remarkable sustainability trends in GA as well as heightened efforts to improve its emissions profile (noise, pollutants, CO2) and environmental reputation, for instance by the increased use of electric aircraft, especially for private pilot training.

4. 3. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
   Keywords : ;

   Abstract : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. READ MORE

5. 4. IC-Engine Source Characterisation and exhaust system simulations

   University essay from KTH/Marcus Wallenberg Laboratoriet MWL

   Author : Pontus Gräsberg; [2021]
   Keywords : IC-engine; source characteristics; Multiload method; one-port source; exhaust system; Bränslemotor; källkarakterisering; avgassystem;

   Abstract : To be able to predict the sound pressure level emitted by a exhaust system one must be able to describe the source. The source in the form of an engine can linearly be described as a source strength and a source impedance. An IC-engine can acoustically have a non-linear part meaning that the source characteristics have a dependency on the load. READ MORE

6. 5. Parameter setting on catalytic controller : Using Design of Experiments and Scanning Electron Microscope Analysis

   University essay from Högskolan i Jönköping/JTH, Produktutveckling

   Author : Unnikrishnan Asan Janardhanan Pillai; Dharani Shanmugavel; [2017]
   Keywords : Design of Experiments; Catalytic converter; Catalyst deactivation; Engine emission control; Scanning Electron Microscope;

   Abstract : This thesis work has been conducted in the Handheld Laboratory at Husqvarna AB with the purpose of finding the parameters responsible for the performance of the catalytic converters used in the test rig. The catalytic converters are used in the test rig during the long term testing of the chain saws to reduce the hydrocarbon content from the exhaust before it enters into the environment. READ MORE
