  1. 1. Characterization of an Electrical Sensor for Combustion Diagnostics

    Detta är en avhandling från Combustion Physics, Lund Institute of Technology

    Författare :Axel Franke; Lund University.; Lunds universitet.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

    Sammanfattning : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. LÄS MER
