Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

opposed-piston (OP) heavy-duty diesel engine achieved Ultralow NO x (ULNO x ) performance results. In that mode, Achates was able to reduce NO x below the original target and increase exhaust temperatures further. Post-turbine exhaust gas temperature was between 284 °C and 328 °C everywhere between 25% load and 100% load.

Study links exposure to diesel exhaust particles to pneumococcal disease susceptibility

Green Car Congress

Researchers from the University of Liverpool, Queen Mary University, London and Trinity College Dublin have linked exposure to diesel exhaust particles (DEPs) to susceptibility to pneumococcal disease. Many of these fatalities have been linked to exposure to high levels of airborne particulates, such as diesel exhaust particles (DEPs).

Study suggests particulates from brake dust may have same harmful effects on immune cells as diesel exhaust

Green Car Congress

Metal particles from the abrasion of brake pads (brake abrasion dust, BAD) may cause inflammation and reduce the ability of immune cells to kill bacteria, similarly to particles derived from diesel exhaust particles (DEP), according to a new study led by researchers at King’s College London. It is estimated that only 7% of PM 2.5

Japan, China researchers develop plasma-assisted MnO2 filter that produces zero-NO2, -SO2 diesel exhaust

Green Car Congress

This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. 2018.12.077. 2018.12.077.

Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

The engine was also equipped with an electrically driven volumetric pump in the exhaust gas recirculation (EGR) path which gives the freedom to set any desired EGR rate, independently from the pressure ratios across the turbocharger. The common rail pump was externally lubricated by engine oil so that it can handle the low fuel lubricity.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

The scientists showed that there are a number of organic molecules from diverse sources present in modern concrete structures and asphalt pavements: phthalates, diesel exhaust particulates, surfactants, and windshield washer fluids.

Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

TDI diesel for Euro 6d; SCR twin-dosing. Volkswagen continues to refine its most important diesel engine, the 2.0-liter With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company.
