  1. 1. Okt. 2022 · Although the natural luminance of the fuel film flame shows no significant difference from the conventional impingement spray, it burns quietly and lasts nearly 100ms, which is much longer The ...

  2. 26. Feb. 2018 · This study shows fuel film measurements in a spark-ignited direct injection engine using refractive index matching (RIM). The RIM technique is applied to measure the fuel impingement of a high research octane number gasoline fuel with 30 vol% ethanol content at two intake pressures and coolant temperatures. Measurements are conducted for an alkylate fuel at one operating case, as well. It is ...

  3. 11. Okt. 2001 · 1. Introduction. The fuel/air mixing processes in spark ignition (SI) engines are important to maximise efficiency and reduce emissions. During preparation for combustion, the fuel flow exists in several streams, these being vapour, liquid droplets and liquid wall film. As the fuel moves towards the cylinders, a continuous exchange of mass ...

  4. 25. Aug. 2022 · High performances of thin-film-solid oxide fuel cells with direct ammonia fuel Three cells were first tested with wet H 2 fuel (3% H 2 O) to verify the integrity of each cell and compare its performance with that of the ammonia fuel.

  5. 15. Dez. 2022 · Because suspended droplets above deposited fuel film would distribute the LIF signal, the transient states of deposited fuel film were difficult to capture [31]. In the measurement process, the high-speed camera records the deposited film image with a 5 ms delay after the end of injection to ensure the reliability of fluorescence signal. In the PDA experiment, only the main impingement regions ...

  6. 25. Jan. 2023 · Fuel film combustion and its effect on wall heat load in diesel engines are studied. • Fuel film is ignited by acetylene premixed flame, confirming wall-attached burning. • Fuel film flame is flat on the wall and burns quietly but lasts for as long as 100 ms. • Fuel film burning exerts great heat load on the wall, with peak heat flux of ...
