  1. 1. Chemistry of Combustion Products Investigation of Combustion Chamber Deposits Formed in a Gasoline Direct Injection Stratified Charge SI Engine

    Författare :Farshid Owrang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gasoline fuels; SI engine; gasoline direct injection; stratified charge; combustion chamber deposits; engine oil; oxidation; in situ measurement; thermal desorption; GC MS; fast neutron activation analysis; spin-lattice relaxation constant; NMR;

    Sammanfattning : The aim of this work was to characterize deposits formed in the combustion chambers of a gasoline direct injection stratified charge SI engine. The engine was run with several types of gasoline fuels and a special reference engine oil. LÄS MER

  3. 2. Optical Diagnostics for Engine Efficiency in Gasoline Compression Ignition

    Författare :Miao Zhang; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PPC; Optical engine; Engine Eciency; Multiple-injection strategies; Thermodynamic analysis;

    Sammanfattning : The internal combustion engine has played a significant role in a vast number of applications from small cars to giant tankers, setting people free from geographical barriers and heavy labor. However, it has also generated many tons of harmful emissions and CO2that damage to humans and the environment. LÄS MER
