  2. 1. Operating cycle representations for road vehicles

    Author : Pär Pettersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; full vehicle simulation; energy usage; transport operation description; road format; CO2 emissions;

    Abstract : This thesis discusses different ways to represent road transport operations mathematically. The intention is to make more realistic predictions of longitudinal performance measures for road vehicles, such as the CO2 emissions. READ MORE

  4. 2. The operating cycle representation of road transport missions

    Author : Luigi Romano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating cycle; transport application; road mission; probability distributions; stochastic processes; energy estimation;

    Abstract : The difficulties that conventionally road vehicles are facing in meeting regulation standards require ad-hoc solutions. Moreover, the impellent shift of paradigm towards full electrification and partial automation is posing great challenges to the automotive industry, which has set a zero-emissions target to be reached within a short time horizon.

  5. 3. Mathematical modelling of operating cycles for road vehicles

    Author : Luigi Romano; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy estimation; transport application; operating cycle; autoregressive models; road mission; stochastic models;

    Abstract : Difficulties that commercial vehicles are facing in meeting regulation standards require ad-hoc solutions. Emissions can be dramatically lowered if the characteristics of the transport application are known in advance. READ MORE

  6. 4. Waste Heat Recovery in Heavy Duty Diesel Engines

    Author : Jelmer Johannes Rijpkema; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Flash Cycle; Heavy Duty Diesel Engine; Organic Rankine Cycle; Trilateral Flash Cycle; Transcritical Rankine Cycle; Internal Combustion Engines; Waste Heat Recovery;

    Abstract : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). READ MORE

  7. 5. Road Design for Future Maintenance : Life-cycle Cost Analyses for Road Barriers

    Author : Hawzheen Karim; Björn Birgisson; Ulf Isacsson; Rolf Magnusson; Robert Thomson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road maintenance; road management; road planning; road design; life-cycle cost; road barrier; guardrails; cable barrier; road traffic injuries; barrier collisions and barrier repair costs.; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Vägprojektering för minskade drift- och underhållskostnader;

    Abstract : The cost of a road construction over its service life is a function of design, quality of construction as well as maintenance strategies and operations. An optimal life-cycle cost for a road requires evaluations of the above mentioned components. READ MORE
