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...

Performance and environmental impact assessment of diesel engine operating on high viscous punnai oil-diesel blends
Environ Sci Pollut Res Int. 2022 Apr 14. doi: 10.1007/s11356-022-20211-3. Online ahead of print.ABSTRACTThe increasing demand for energy consumption because of the growing population and environmental concerns has motivated the researchers to ponder about alternative fuel that could replace diesel fuel. A new fuel should be cheaply available, clean, efficient, and environmentally friendly. In this paper, the engine operated with neat punnai oil blends with diesel was investigated at various engine load conditions, keeping neat punnai oil and diesel as base fuels. The performance indicators such as brake specific energy con...

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...

Investigation on methanol –gasoline–aluminum oxyhydroxide nanoparticle blends on the emission characteristics of an SI engine
AbstractExperiments were carried out to reduce the harmful exhaust emissions from the engine through various in ‐cylinder techniques such as nanoparticles blended fuel. In this present investigation, the effect of methanol‐gasoline fuel blends (M10, M30, and M50) and neat gasoline (G100) on a single‐cylinder four‐stroke SI engine was studied under idle throttle operating conditions to obtain the chara cteristics of total fuel consumption and exhaust emissions. The fuel‐borne nanoparticles such as aluminum oxyhydroxide [AlO(OH)] from 50 to 150 ppm were mixed with methanol gasoline blends. AlO(OH) behaves like a f...

Effect Of n-amyl alcohol/biodiesel blended nano additives on the performance, combustion and emission characteristics of CRDi diesel engine
Environ Sci Pollut Res Int. 2021 Mar 6. doi: 10.1007/s11356-021-13165-5. Online ahead of print.ABSTRACTThis paper deals with the study on the influence of the effects of iron oxide nanoparticle additives when added to ternary fuel (diesel + mahua methyl ester + pentanol) on the emission, combustion, and performance characteristics of a four stroke, single cylinder, common rail direct injection diesel engine working at a constant speed and varying operating scenarios. Doping is done in various proportions to the nanoparticle additives with the help of a homogenizer and ultrasonicator where the cationic surfactant used is CT...

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...

Influence of antioxidant additives on performance and emission characteristics of beef tallow biodiesel-fuelled C.I engine.
Abstract This work analyses the performance and emission characteristics of biofuelled compression ignition (C.I) engine with the implementation of an antioxidant. Using the transesterification process with sodium hydroxide as a catalyst, the beef tallow methyl ester (BTME) was obtained from the beef tallow oil. Poor physical properties of biodiesel (beef tallow oil (BTO)) namely high viscosity and density cause atomization problems leading to higher smoke, hydrocarbon and carbon monoxide emissions. The purpose of this work is to enhance the performance aspects, to limit smoke emissions from BTO operation and to e...

Performance and emission reduction characteristics of cerium oxide nanoparticle-water emulsion biofuel in diesel engine with modified coated piston.
Abstract In the present scenario, the utilization of petroleum fuel is expanding forcefully worldwide in the vitality store and plays a highly hazardous role in the ecological system. Biofuel stands out among the most tenable keys for this issue. The lemongrass oil is used as a biofuel because of low density and viscosity when compared with diesel. The lemongrass oil is extracted by steam distillation process. In the present investigation, partially stabilized zirconium, due to its higher thermal conductivity, is selected as coating material. The top surface of the piston and the inlet and exhaust valves are coate...
