2. 1. The Influence of Multiple Injections on Combustion : an Experimental Investigation

   Author : Rickard Ehleskog; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple injections; direct injected DI diesel engines; diesel sprays; emissions; Internal combustion engines; diesel combustion;

   Abstract : The high fuel efficiency and torque of the diesel engine has made it the obvious choice for heavy duty applications for a long time. In addition, these characteristics of the modern super-charged HSDI diesel engine also make it very suitable and popular for car applications. READ MORE

4. 2. Spray combustion with multiple-injection in modern engine conditions

   Author : Ahmad Hadadpour; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spray combustion; Multiple-injection; Internal combustion engine; LES; FGM; ESF;

   Abstract : Combustion of fuel in diesel engines emits substances harmful to the environment such as soot. These emissions can be reduced by either in-cylinder treatments or after-treatments. One of the common in-cylinder treatments is multiple-injection, which divides a single fuel injection to multiple smaller injections. READ MORE

5. 3. Separation of Pharmaceuticals by Capillary Electrophoresis using Partial Filling and Multiple-injections

   Author : Henrik Lodén; Curt Pettersson; Torbjörn Arvidsson; Ahmad Amini; Morgan Stefansson; Uppsala universitet; []
   Keywords : Capillary Coating; Chiral Separation; Enantiomers; Mass-spectrometric Detection; Method Validation; Multiple-injection Capillary Zone Electrophoresis; Non-aqueous Capillary Electrophoresis; Organic Solvents; Pharmaceutical Analysis; Quantitative Analysis;

   Abstract : Different multiple-injection methodologies and the partial filling technique (PFT) have been utilized for separation of pharmaceuticals by capillary elec-trophoresis. In multiple-injection capillary zone electrophoresis (MICZE), the samples and all standards, used for construction of the calibration curve, are analyzed within a single run. READ MORE

6. 4. Injection Strategies for Heavy Duty DI Diesel Engines
