Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al. PAHs have a dark side, too. Zagidullin, Valeriy N. Mebel, Ralf I.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This study incorporates the near-term global warming potential of methane leakage emissions of natural gas and natural gas-derived hydrogen pathways. Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either.

Green Motorsports: IndyCar Switches to Cleaner Cars & Fuel

Clean Fleet Report

IndyCar will make the switch to hybrid gasoline-electric engines with the 2024 race season, joining F1 and IMSA , two race series that already use hybrid systems. Shell says this new race fuel “enables at least 60% greenhouse gas emissions reduction compared to fossil-based gasoline” on a lifecycle basis compared to the current fuel.
