No data was available to compare trends in ΔPM 2.5 between the two periods.
Additionally, LNG engines are tuned to either emit low nitrogen oxide (NO x ) emissions—at the cost of higher methane emissions in some cases—or to incorporate NO x reduction technologies such as exhaust gas recirculation (EGR) or selective catalytic reduction (SCR).
It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution. Everything else—pistons, porting and crankcase, bearings, exhaust, etc.—were Lubrication proved to be an issue.

Under this funding, EPA anticipates awarding between 10 and 20 assistance agreements.
Previous studies have shown that it is possible to operate diesel engines with 100% DME, but that this requires significant effort (injection components, combustion process, exhaust gas aftertreatment, tank system) in terms of conversion. Ideally, the conventional system components already installed in the vehicle are retained.
Exposure to these pollutants was most elevated in the coach located closest to the locomotive: geometric means were 126,000# cm -3 for UFP, 249 μm 2 cm −3 for LDSA, and 17,800 ng m −3 of BC; these concentrations are much higher than those previously reported for other modes of public transportation. Preliminary results are positive.

Their study is publishedin the ACS journal Environmental Science & Technology.
Stuart Grange works in Empa’s Air Pollution/Environmental Technology Laboratory and also at the Wolfson Atmospheric Chemistry Laboratories at the University of York. Together with his colleagues, he used a special instrument to examine the exhaust plumes of 23,000 passing cars and analyzed the levels of NO x and CO 2.
Engineers focused on improving thermal efficiency and reducing friction of the engine’s internal moving parts, especially during warm-up—the time when an engine emits higher levels of CO 2 and other pollutants. An exhaust manifold cast into the cylinder head. The one-piece assembly lowers the temperature of the exhaust gases.
demonstrates that mandatory upgrades to diesel truck fleets serving the Port of Oakland are responsible for significant reductions in two major air pollutants. Pollutant concentrations were measured at high time resolution in the exhaust plumes of more than a thousand drayage trucks as they drove toward the Port on a major access road.

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants. Older models don’t even have the emission-control features that newer ones do.
At a February 2018 meeting, an IMO-subcommittee announced a proposal to ban the carriage of non-compliant bunker fuel (fuel that exceeds the 0.50% sulfur limit) aboard ships that have not installed on-board ship scrubbers (exhaust gas cleaning systems), Barrow said. As of August 2017, approximately 360 ships had installed scrubbers.
