## Description

- description: "We have developed a time-resolved Compton-scattering imaging technique
    for visualizing gas behaviours in operating internal combustion engines. This
    technique employs a digital processing system to record both the pulse height
    and the timing of detected X-rays, enabling the derivation of Compton-scattered
    X-ray spectra for each crank angle, which corresponds to the piston position.
    The observed crank-angle dependency of Compton-scattered X-ray intensity allowed
    us to successfully capture the density changes of the gas in the combustion chamber
    associated with piston motion and combustion. In addition, the capability of temperature
    estimation is discussed with a combination of X-ray Compton-scattering experiments
    and pressure measurements. This study demonstrates that time-resolved Compton-scattering
    imaging is a powerful and unique technique for characterizing gas behaviours in
    an operating internal\r\ncombustion engine."
