  2. 1. Centrifugal pendulum vibration absorbers in heavy-duty truck powertrains : Modelling, simulation and experimental investigations

    Author : Erik Gomez; Leif Kari; Ines Lopez Arteaga; Ole Balling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; centrifugal pendulum vibration absorber CPVA ; powertrain; heavy-duty truck; driveline; transmission; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The heavy-duty vehicle industry is facing big challenges to reduce CO2 emissions. Although electrification is on the rise, the combustion engine will used for some time to come. READ MORE

  4. 2. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation

    Author : Jakob Sjöstrand; Leif Kari; Ines Lopez Arteaga; Per Erik Austrell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dry clutch system; Engagement; Disengagement; Dry-friction; LuGre friction model; Heavy-truck powertrain; Teknisk mekanik; Engineering Mechanics;

    Abstract : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. READ MORE

  5. 3. On integrated modularization in heavy-duty truck architecting

    Author : David Williamsson; Ulf Sellgren; Anders Söderberg; Johan Malmqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modularization; Module; Product Architecture; Cyber-Physical System; Machine Design; Maskinkonstruktion;

    Abstract : Road transports face increasing challenges with respect to safety, legislations on lower emissions and traffic congestion, as well as numerous business challenges related to paradigm shifts in technology, tightened delivery times and cost constraints. Combination of truck electrification and automation may be utilized to address some of these issues. READ MORE

  6. 4. Deactivation of emission control catalysts for heavy-duty vehicles : Impact of biofuel and lube oil-derived contaminants

    Author : Sandra Dahlin; Lars Pettersson; Isabella Nova; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; catalyst deactivation; diesel oxidation catalyst; sulfur; phosphorus; biodiesel; heavy-duty; emission control; regeneration; alkali metals; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; katalysatordeaktivering; dieseloxidationskatalysator; svavel; fosfor; biodiesel; tunga dieselmotorer; avgasrening; regenerering; alkalimetaller; Chemical Engineering; Kemiteknik;

    Abstract : Catalytic emission control is used to reduce the negative impact of pollutants from diesel exhausts on our health and on the environment. For a heavy-duty truck, such a system consists of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), a selective catalytic reduction (SCR) catalyst, and an ammonia slip catalyst (ASC).

  7. 5. Methods to quantify and qualify truck driver performance

    Author : Iulian Carpatorea; Slawomir Nowaczyk; Thorsteinn Rögnvaldsson; Wahde Mattias; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Driver performance; heavy-duty vehicle; fuel economy; fuel consumption; fuel prediction; truck driver;

    Abstract : Fuel consumption is a major economical component of vehicles, particularly for heavy-duty vehicles. It is dependent on many factors, such as driver and environment, and control over some factors is present, e.g. route, and we can try to optimize others, e. READ MORE
