Tula presenting diesel Dynamic Skip Fire technology at Future Diesel Powertrain Summit in Shanghai

Green Car Congress

Tula Technology is presenting its diesel Dynamic Skip Fire (dDSF) technology ( earlier post ) at the 4 th Future Diesel Powertrain Summit China 2020 on 24-25 September 2020 in Shanghai, China. Cylinder deactivation also reduces excess engine airflow, increasing exhaust temperatures. dDSF Simulation Project.

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. Organic matter in water accelerates deterioration of asphalt pavements.

Audi presents latest SQ5 TDI diesel; 48V MHEV & electric compressor

Green Car Congress

Audi has introduced the latest version of the SQ5 TDI diesel. The SQ5 TDI was first introduced in the fall of 2012 as the first Audi S model powered by a diesel engine. An actuator in the exhaust system, as fitted to the first SQ5 TDI, gives the V6 a sonorous sound. lb-ft) of torque. Many details of the V6 3.0 liters (0.2

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards.

SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Southwest Research Institute (SwRI) is helping a client develop a simple post-refinery treatment process that reduces exhaust emissions from diesel engines by overcoming the soot/nitrogen oxides (NO x ) reduction trade-off that has plagued engine researchers for decades.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

Diesel-powered commuter trains may expose their passengers to elevated levels of certain black carbon and ultrafine particles, especially in the coach directly behind the locomotive, according to a new study from researchers at the University of Toronto. A paper on the study is published in the journal Atmospheric Environment.

Study identifies combustion-derived nanoparticles in diesel exhaust as the predominant mediator for adverse cardiovascular events

Green Car Congress

A European study lead by scientists at the University of Edinburgh (UK) has found that the combustion-derived ultrafine particles from diesel fuel are the predominant mediators of the adverse effects—harming blood vessels and increasing the chances of blood clots forming in arteries, leading to a heart attack or stroke.
