  4. 2. Simplified models for emission formation in diesel engines during transient operation

    Author : Anders Westlund; Hans-Erik Ångström; Martti Larmi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; emission modeling; transient operation; NOx; Soot; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : The work presented in this thesis is the result of the KTH CICERO project “Dynamic Engine Performance” in which the main objective was to develop simple models foremission formation. The demand for such models is increasing, mainly due to the tightening emission legislation for diesel engines which has lead to more complex engines and thereby more laborious development and calibration processes.

  5. 3. Evaluation of a Variable Nozzle Turbine Turbocharger on a Diesel Engine under Steady and Transient Conditions

    Author : Ralf Barkhage; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; diesel engine; emissions; transient operation; control system; fuel economy; variable geometry turbocharging; engine performance; variable nozzle turbine; supercharging;

    Abstract : The growing global call for reduced emissions and fuel consumption together with the market call for engines with higher power density and application-oriented torque curves can be met using turbochargers with variable geometry turbines (VGT). The second generation of VGT turbochargers is currently being developed and is starting to appear on the market. READ MORE

  7. 5. Measuring and Predicting Transient Diesel Engine Emissions

    Author : Anders Westlund; Hans-Erik Ångström; Rolf Egnell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emission modelling; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract :   Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organs around the world that gradually have made the manufacturers transform their engines to today’s complex high-tech products. READ MORE
