New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As testament to the filtration efficiency of the latest gasoline particulate filters (GPFs), tailpipe mass emissions are now as low as 0.02

European Commission proposes Euro 7 standards

Green Car Congress

The European Commission presented its proposal for Euro 7 standards to reduce air pollution from new motor vehicles sold in the EU. The Euro 7 standards rules bring emission limits for all motor vehicles, i.e., cars, vans, buses and lorries under a single set of rules. These rules will apply to all vehicles, including electric ones.

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.

UC Riverside team wins EPA design contest with lawnmower exhaust aftertreatment device

Green Car Congress

A team of University of California, Riverside Bourns College of Engineering students have won an EPA student design contest for developing an exhaust aftertreatment device that cuts CO, NO x and PM emissions from lawnmowers. Then, an ultra-fine spray of urea solution is dispersed into the exhaust stream for catalytic NO x reduction.

Promising Delphi 1st-gen Gasoline Direct Injection Compression Ignition engine meeting ultra fuel efficient program targets

Green Car Congress

GDCI engine was significantly better than advanced production spark injection gasoline engines, and comparable to very efficient hybrid vehicle engines at their best efficiency conditions (214 g/kWh). This early work established that gasoline-like fuels with high resistance to autoignition are preferred for PPCI. 35% (PFI baseline).

ExxonMobil, Corning and Toyota develop onboard membrane system to separate gasoline into octane fractions to optimize engine efficiency and performance

Green Car Congress

ExxonMobil, Corning and Toyota have collaborated to develop an Onboard Separation System (OBS) to optimize gasoline engine efficiency and performance. The novel polymer-ceramic composite monolith membrane has been demonstrated to be stable to E10 gasoline, and typically provides 20% yield of ?100 —Partridge et al. The OBS system.
