Study on promotion of lean combustion by oxygen enrichment using a rapid compression expansion machine

open access: yesNihon Kikai Gakkai ronbunshu, 2021
While lean combustion in SI engine is one of the promising methods to increase the thermal efficiency and reduce the pollutant emissions, it causes instability of ignition and combustion due to the low burning velocity.

Broadband dual-frequency comb spectroscopy in a rapid compression machine

open access: yesOptics Express, 2019
We demonstrate fiber mode-locked dual frequency comb spectroscopy for broadband, high resolution measurements in a rapid compression machine (RCM). We apply an apodization technique to improve the short-term signal-to-noise-ratio (SNR), which enables broadband spectroscopy at combustion-relevant timescales. We measure the absorption on 24345 individual

Development of a diesel surrogate for improved autoignition prediction: Methodology and detailed chemical kinetic modeling

open access: yesApplications in Energy and Combustion Science, 2023
While the surrogate fuel approach has been successfully applied to the simulation of the combustion behaviors of complex gasoline and jet fuels, its application to diesel fuels has been challenging.
