Control of emissions in an internal combustion engine: first approach for sustainable design

Abstract

A mathematical model of emissions was developed in a Twingo D7F engine. The effects of variations in compression ratio, fuel/air equivalence ratio, spark advanced and combustion duration under pollutant emissions were studied. Analysis and data collection were performed in an engine bank using a data acquisition system integrated to an Interactive Engineering Environment. A control strategy was implemented to guarantee emissions reduction.

Experimental Study of Exhaust Manifold Water Injection on Emission of CI Engine Fueled with Madhuca Longifolia and Diesel Blends

“…NOx emissions were reducing as water injection flow rate increases and the trend line of the same is almost linear in behavior. Same trend of NOx emission reduction with increase in water injection flow rate has been observed for all the blends (B10, B20, B30), CR (15,16,17,18) and for both the loading conditions (75% and 100%). ii.…”

“…When excessive concentrations of nitrogen-containing fuel additives contribute reaction than only fuel NOx is produced [16]. As NOx emissions are so harmful restrictions limiting the quantity of these gases can be emitted are becoming stronger through governing rules [17]. Earth surface-level ozone generation, smog and Acid precipitation are the events which initiated by NOx emissions [15].…”

Impact of Internal Combustion Engine on Energy Supplyand its Emission Reduction via Sustainable Fuel Source

“…Table 6 shows an average global everyday requirement for vehicle fuels and the third quarter of 2018. Amaya et al 80) added sources of Hydrocarbons emissions as oxides of nitrogen (NOx), nonstoichiometric air-fuel ratio, incomplete combustion, oils on combustion chamber walls, crevice volumes, deposits on combustion chamber walls, and Carbon monoxide emissions. Ting et al 81) scientifically uncovered GHG Emission inventories of selected eight urban sectors which include; residential land-use, commercial and uses, institutional land uses, industrial land uses (energy usage), industrial emission from the fugitive, transportation land use from vehicles, rail-way, from waterways, agricultural land uses and related waste disposal together with treatment land-fills are in the inventory.…”

“…Andres, Adalberto et al 80) and Lestari et al 83) academically stated that fuel combustion results in environmental pollution which has direct effects on climate change through acid rain, global warming, smog, odors, and all related to respiratory tract infection together with diseases. Scientifically indicates major causes of emission to include dissociation of nitrogen, nonstoichiometric combustion related conditions, impurities present in the fuel and air together with other motor processing factors.…”

“…Scientifically indicates major causes of emission to include dissociation of nitrogen, nonstoichiometric combustion related conditions, impurities present in the fuel and air together with other motor processing factors. Hydrocarbons (HC), carbon monoxide CO, nitrogen oxides (NOx), sulfur, and solid carbon entities are major concerns because of their adverse influence on both an individual's wellbeing and the environment (Amaya et al ) 80) .Bright, Festus et al 84) covered the global warming issues as the major predicament to most economies particularly that of Emerging 7 (E7) economies. The E7 nations set-asides CO2 emission mitigating policies through cutting down the CO2 emission with the trajectory of the economies.…”
