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.

International consortium working on new sensor technology to measure real-world, in-use vehicle emissions

Green Car Congress

As part of the Horizon 2020 research project CARES (City Air Remote Emission Sensing), an international research consortium is working on new contactless exhaust measurement methods that will enable municipalities to take emission-reducing measures. The aim is to detect the exhaust class of each individual vehicle using these measurements.

BP awards Colorado State University $5M to research technology for oil recovery from watered-out wells

Green Car Congress

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. Typically, wells are abandoned after they are no longer producing oil or gas at a rate that is economically viable. Bill Bailey et al. 2000) Water Control.

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

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. Taking IRENA’s REmap scenario as a reference, renewable hydrogen could deliver 5% of total final energy demand in 2050.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

Now, researchers at Kumamoto University in Japan, led by Professor Masato Machida, have developed a new composite material—a CeO 2 -grafted MnFeO y (CeO 2 /MnFeO y ) as a substitute for the conventional CeO 2 material in three-way catalysts. wt% Pd/A2O3, and the reference catalyst was a mixture of 1 wt% Rh/CeO 2 and Pd/A 2 O 3.

New study finds that ship emissions from HFO and diesel adversely affect pulmonary macrophages

Green Car Congress

Often referred to as scavenger cells, they absorb and engulf microorganisms. Since macrophages also play a key role in lung diseases such as COPD (chronic obstructive pulmonary disease), the new study is important for understanding the health risks of ship exhausts. Their open access paper is published in the journal PLOS ONE.
