  1. 1. Contributions to the Development of Automobile Electrical Power System

    Author : Urban Kristiansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical power system; battery state of charge; automobile; start system; battery; alternator; generator; starter;

    Abstract : Development trends for the Automobile Electrical Power System (AEPS) are discussed. Two systems are compared with respect to cost, weight, number of components, reliability and noise. READ MORE

  2. 2. Comparison of Different Electrical Machines for Belt-driven Alternator and Starter

    Author : Dan Hagstedt; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Belt-driven Alternator and Starter; Permanently Magnetised Synchronous Machine; Electrically Magnetised Synchronous Machine; Series Magnetisation Synchronous Machine; Hybrid Magnetised Synchronous Machine;

    Abstract : This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. READ MORE

  3. 3. Belt Driven Alternator and Starter with a Series Magnetized Synchronous Machine Drive

    Author : Tomas Bergh; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. READ MORE

  4. 4. Modeling of a Free Piston Energy Converter

    Author : Jakob Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Free piston engine; detailed chemistry; variable compression; computational fluid dynamics CFD ; combustion;

    Abstract : ABSTRACTThe Free Piston Energy Converter (FPEC) is a new type of automotive prime mover, offering high efficiency in conjunction with low emissions. The FPEC essentially consists of two opposing cylinders with a linear alternator incorporated in-between that produces electric power directly. READ MORE

  5. 5. Hydrogen generation from dimethyl ether by autothermal reforming

    Author : Marita Nilsson; Lars Pettersson; Ann Cornell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; dimethyl ether; fuel cell; hydrogen; palladium; reforming catalyst; temperature-programmed reduction; truck idling; X-ray diffraction; zinc; Chemical engineering; Kemiteknik;

    Abstract : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. READ MORE
