“…Reducing exhaust emissions is essential in addressing pollution and climate change [11]. Many great efforts to decarbonize the transportation sector have been made [12][13][14][15] and are continually being studied [16][17][18]. Thus, the reduction of unwanted exhaust gases is indispensable in developing high-performance automobile engines.…”

Temporally and spatially resolved laser-induced breakdown spectroscopy (LIBS) was applied to a four-stroke, single-cylinder test engine’s cyclic exhaust gas to demonstrate engine performance. The LIBS technique provided quantitative air-to-fuel ratio (A/F) measurements by generating localized breakdown plasma during the compression and exhaust strokes. The results showed that the timing and duration settings of the emission energy ionization and molecular spectra affect the intensity peaks. Optimum measurements performed between 200 ns and 10 ms after breakdown resulted in observed atomic spectra of CI (248 nm), Hβ (485 nm), Hα (656 nm), NI (745, 824 nm), and OI (777, 844 nm). The intensities of CI (248 nm) and Hα (656 nm) decreased with increasing A/F, whereas the intensity ratios of NI and OI remained constant. A decrease in the intensity ratio of C/O and Hα/O was observed as the A/F increased. This study is a major step toward defining a means of using LIBS to control the A/F ratio in gasoline engines by focusing on the exhaust gas rather than the flame.

Biorenewable energy resources can be crucial in neutralizing the transportation sector's greenhouse gas emissions. However, the direct use of biorenewable fuels in existing gasoline engines is challenging and requires several modifications. On the contrary, blending compatible biorenewable fuels in limited amounts as an additive in conventional gasoline does not necessarily require any modifications in the engine. Thus, the present review critically asses the physiochemical and fuel properties of biomass‐derived oxygenates such as alcohols, ether, furans, glycerine derivatives, alkyl levulinates, bio‐oils, and esters to understand their full potential as a gasoline additive. Properties such as research octane number (RON), motor octane number (MON), density, volatility characteristics, calorific value, and viscosity of the bio‐based oxygenates have been discussed. Moreover, emission characteristics such as NOx, CO, unburnt, HC, and CO2 of oxygenates reformulated gasoline have been discussed.
