Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050. There is no immediate concern for copper resources, but the average ore grade is declining as higher grade deposits become exhausted. According to the IEA, less than 0.1%

UCL, BP team study on combustion and emissions characteristics of a range of fuel molecules from lignocellulosic biomass

Green Car Congress

The researchers suggested that their results can be used to aid in selecting at what stage lignocellulose should be chemically modified so as to produce a viable biofuel molecule with optimal combustion characteristics and exhaust gas emissions. Their paper is published in the ACS journal Energy & Fuels. Injection timing was kept fixed at 7.5

2025 Hyundai Ioniq 5 N Review – Shockingly Spicy

The Truth About Cars

The brakes were stout and consistent with no fade – for reference my session was mid-morning on a warm day, and I had three consecutive three-lap runs with a cooldown lap each time and a few minutes break in between. That means fake exhaust sounds, paddle shifting for the “gears”, the whole works.
