  1. 1. On the Combustion Characteristics of Closely-Coupled LD Diesel Injection Strategies

    Author : Michael Denny; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel combustion; Closely-Coupled Pilot; Closely-Spaced Pilot; Combustion Noise; Heat release rate shaping; Multiple-injection strategy; Formaldehyde PLIF;

    Abstract : Multiple-pilot injection strategies with both moderate and short time separations (dwells) are investigated in a light-duty diesel engine. Both conventional and optical engine experiments are performed. READ MORE

  2. 2. Alcohol Flexible Dual-Fuel Direct Injection Engine

    Author : Michael Saccullo; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel spray; Dual-fuel; Dual-direct injection; E85; Ethanol; Heavy duty engine; Diffusion combustion; Methanol;

    Abstract : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. READ MORE

  3. 3. Design and Optimization of In-Cycle Closed-Loop Combustion Control with Multiple Injections

    Author : Carlos Jorques Moreno; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Combustion; Pilot-Main Injection; Pilot Mass Estimation; Cylinder Volume Estimation; Bayesian Estimation; In-Cycle Combustion Controllability; In-Cycle Combustion Control; Model Predictive Combustion Control; Stochastic Combustion Optimization; Hardware Quantification;

    Abstract : With the increasing demand of transportation, biofuels play a fundamental role in the transition to sustainable powertrains. For the increased uncertainty of biofuel combustion properties, advanced combustion control systems have the potential to operate the engine with high flexibility while maintaining a high efficiency and robustness.

  4. 4. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion

    Author : Pablo Garcia; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual Fuel; Diesel; Natural Gas; Pilot Injection; Combustion Efficiency; Methane; Nitrogen Oxides; Lean operation; Ignition;

    Abstract : Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. READ MORE

  5. 5. Optical and laser diagnostics : The versatility of Imaging

    Author : Alexios Matamis; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; methanol; COMBUSTION; diesel; schlieren; spray; imaging; pilot-injection; high-speed imaging; Fysicumarkivet A:2021:Matamis;

    Abstract : Optical and laser diagnostics is a field where optical techniques are developed that offer remote, non-intrusive measurements in order to characterise a system. Imaging is a big part of this field and the versatility it offers makes it a great tool in the hands of researchers and in practical applications. READ MORE
