2. 1. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

   Author : Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

   Abstract :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. READ MORE

4. 2. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine

   Author : Monica Larsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Alternative Fuels; Fischer-Tropsch; GTL;

   Abstract : Alternative fuels for Diesel engines include ester-based fuels (derived from sources such as rapeseed, soybeans and palm oil), dimethyl ether, and various synthetic fuels. Use of these fuels could contribute to a cleaner environment, reduce global warming and improve the human health by reducing levels of harmful emissions. READ MORE

5. 3. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

   Author : Lars Christian Riis Johansen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

   Abstract : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. READ MORE

6. 4. Fischer-Tropsch and FAME Fuels as Alternatives for Diesel Engines; an Experimental Study

   Author : Monica Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emissions; SME; Fischer-Tropsch; NOx; Combustion; Alternative fuels; Soot; Biodiesel; RME; FAME; GTL; PME;

   Abstract : Research into alternative fuels is necessitated by our heavy reliance on limited oil reserves and increasingly strict emissions legislation. The studies reported in this thesis involved conducting engine tests using alternatives to fossil Diesel fuel in both heavy-duty and light-duty single cylinder engines. READ MORE

7. 5. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions

   Author : Anna Lif; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx; microemulsion; combustion; diffusometry; alternative fuels; emission; emulsion; Fischer-Tropsch; MFC; PM; microfibrillated cellulose; NMR; surfactant; soot; diesel;

   Abstract : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. READ MORE
