Study the effects of dimethyl carbonate as a fuel cetane improver on diesel engine emissions
AbstractIn this work, diesel engine emissions are studied by adding a cetane improver to the engine fuel. Dimethyl carbonate (DMC) additive is used as a cetane improver. A single-cylinder, four-stroke diesel engine is used to test the fuels. Three fuels are selected to run the engine, namely, biodiesel derived from neem oil  + 1 vol% DMC (BD100 + 1DMC), BD100, and diesel. BD100 + 1DMC fuel emits a reduced amount of carbon monoxide and unburnt hydrocarbons compared to diesel under the same operating conditions of engine. The level of nitrogen oxides emission for BD100 + 1DMC is slightly higher compared to diese l a...

Experimental investigation on sucrose/alumina catalyst coated converter in gasoline engine exhaust gas
In this study, a modified catalytic converter was employed to treat the harmful exhaust gas pollutants of a twin-cylinder, four-stroke spark-ignition engine. This research mainly focuses on the emission reduction of unburnt hydrocarbons, carbon monoxide, and nitrogen oxides at low light-off temperatures. A sucrolite catalyst (sucrolite) was coated over the metallic substrate present inside the catalytic converter, and exhaust gas was allowed to pass through it. A scanning electron microscope, X-ray diffraction, and Fourier transform infrared spectroscopy were used to investigate the changes in morphology, chemical compound...

Association of short-term exposure to air pollution with recurrent ischemic cerebrovascular events in older adults
Int J Hyg Environ Health. 2022 Jan 16;240:113925. doi: 10.1016/j.ijheh.2022.113925. Online ahead of print.ABSTRACTThe acute effects of ambient air pollution on recurrence of ischemic cerebrovascular events (ICEs) remains largely unknown. We therefore conducted a time-stratified case-crossover study of 43,896 patients who were 60 years or older and were admitted to hospital for recurrent ICEs including ischemic stroke and transient ischemic attack in Guangzhou, China during 2016-2019. Based on each patient's home address and pollutant data from its neighboring air quality monitoring stations, we used an inverse distance wei...

Association between exposure to ambient air pollution and hospital admission, incidence, and mortality of stroke: an updated systematic review and meta-analysis of more than 23 million participants
ConclusionsExposure to air pollution was positively associated with an increased risk of stroke hospital admission (PM2.5, PM10, SO2, NO2, CO, and O3), incidence (PM2.5, SO2, and NO2), and mortality (PM2.5, PM10, SO2, and NO2). Our study would provide a more comprehensive evidence of air pollution and stroke, especially SO2 and NO2.

IJERPH, Vol. 17, Pages 3896: Environment-Friendly Biodiesel/Diesel Blends for Improving the Exhaust Emission and Engine Performance to Reduce the Pollutants Emitted from Transportation Fleets
In this study, various biodiesel blends (Chlorella vulgaris, Jatropha curcus, and Calophyllum inophyllum) were investigated for fuel characteristics, and engine performance with exhaust emission compared to diesel. Chlorella vulgaris, Jatropha curcus, and Calophyllum inophyllum biodiesel were synthesized by the acid–base transesterification approach in a microwave reactor and blended with conventional diesel fuel by volume. The fuel blends were denoted as MB10 (90% diesel + 10% microalgae biodiesel), MB20 (80% diesel + 20% microalgae biodiesel), JB10 (90% diesel + 10% jatropha biodiesel), JB20 (80% diesel + 2...

Numerical evaluation of pollutant emissions of a two-stroke linear engine.
This study introduced a green engine called free-piston linear engine (FPLE), and performed an evaluation on the pollutant emissions of a diesel FPLE by comparison with a corresponding conventional crankshaft engine (CCE). The combustion reaction and pollutant formation were described by a comprehensive model which considers the special operation mechanism of the FPLE. The effect of dynamic and fuel quantity on the unclean combustion products of the FPLE and the CCE was compared. Results indicate that in the case of the fuel quantity of 7.1 mg condition, the pollutant forming in the FPLE is generally later than that in CC...
