1. 31. High temperature corrosion in exhaust application for heavy-duty trucks

   University essay from KTH/Materialvetenskap

   Author : Alice Moya; [2019]
   Keywords : high temperature corrosion; austenitic steel; cast iron; cast steel; oxidation; exhaust gas; engine; heavy-duty trucks;

   Abstract : Increasing awareness of environmental protection has made both governments and the industry aim for lowering carbon dioxide emissions. For the transport industry this means increasing engine efficiency, replacing fossil fuels with bio-based fuels or full electrification. READ MORE

3. 32. Sensitivity and Uncertainty Analysis of Building Parameters integrating energy, daylight and thermal comfort

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Tian Tan; Magdalena Szumanska; [2019]
   Keywords : Sensitivity analysis; Uncertainty analysis; Multidisciplinary analysis; Building parameters; Energy consumption; Daylight; Thermal comfort; Optimization; Technology and Engineering;

   Abstract : The objective of this thesis was to perform multidisciplinary sensitivity and uncertainty analysis of the building parameters integrating thermal comfort, energy and daylight. The case study of a Danish office building was used for performing the simulations. READ MORE

4. 33. Experimental Study to Reduce CO Emissions in Skellefteå Kraft's 16 MW Bubbling Fluidized Bed Boiler

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : William Johansson; [2019]
   Keywords : ;

   Abstract : Skellefteå Kraft has had high CO emissions problems in a bubbling fluidized bed (BFB) boiler in Malå.Statistical emissions data from 2013 to 2019 shows plant average emissions of 1230 ppm. Thisexceeds the recommended 440 ppm (6 % O2) that Naturvårdsverket proposes (Naturvårdsverket,2005). READ MORE

5. 34. Knock model evaluation - Gas engine

   University essay from KTH/Förbränningsmotorteknik

   Author : Nishchay Sharma; [2018]
   Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering;

   Abstract : Knack i en förbränningsmotor är en typ av onormal förbränning. Det är ett komplicerat fenomen som beror på flera fysiska faktorer och resulterar i högfrekventa tryckoscillationer inuti förbränningskammaren. Dessa oscillationer kan skada motorn och fenomenet hämmar motorns effektivitet. READ MORE

6. 35. Analysis of the South Korean Procedure for the Fuel Consumption and CO2 Emissions from Heavy Duty Vehicles. Sensitivity Analysis of the Fuel Consumption Deviation in Transient Cycles over Steady State Conditions.

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Swarna Manjari Ayyalasomayajula; [2018]
   Keywords : ;

   Abstract : To meet the demands to reduce national energy consumption and greenhouse gas emission targets based on environmental policy, the Ministry of Trade, Industry, and Energy of Korea formed a research consortium consisting of government agencies and academic research institutions to establish the first fuel efficiency standards for Heavy-duty commercial vehicles (HDV). The standards are expected to be introduced at the earliest in 2020 as Phase 1 of the plan. READ MORE
