Pollution has become\na big problem and it is rising every second. There is a diverse set of factors\nbehind this. Still, the primary reason is the exhaust released by the\nautomobiles after several chemical reactions in the engine to power the\nvehicle. It contains multifarious harmful fumes such as oxides of nitrogen,\nsulfur dioxide, carbon monoxide, and particulate matter that is exceptionally damaging\nto the human body when inhaled regularly. Also, it gives rise to global warming,\nwhich is a worldwide concern in the modern world.<\/p>\n\n\n\n

Factors that determine vehicle emission are vehicular technology, fuel quality, regular inspection and maintenance, and last but not the least, traffic and road management. To deal with this vehicular pollution, governments need to enforce emission standards so that the increasing level of harmful fumes can be prevented. As far as the vehicular technology is concerned, automobile manufacturers need to use new technologies in their vehicles to comply with the emission regulations. The Indian government is very is taking steps to tackle the pollution level, particularly for environmental contamination due to the increase in the number of on-road vehicles and the exhaust gases released by them. Indian emission laws follow the pathways of the European Union regulatory. <\/p>\n\n\n\n

The first norms\nof emission in India were implemented in 1991 and 1992 for petrol and diesel\nvehicles, respectively. To reduce the toxic gases and pollutants in the exhaust gas, \na catalytic converter was made mandatory. The government had implemented Bharat\nstage (BS) IV norms starting April 2017 after BS-I, BS-II, BS-III in the past.  To comply with the BS-IV norms, 2 and 3 wheeler manufacturing\ncompanies had to install an evaporative emission control unit to reduce the\namount of fuel that is evaporated when the bike is parked. In the commercial\nvehicle segment, it became necessary for the OEMs to meet the BS-IV standards\nby using a Selective Catalytic Reduction (SCR) & Exhaust Gas Recirculation\n(EGR) technologies in their vehicles. Generally, SCR and EGR technologies are\nused in high horsepower and low horsepower generating vehicles, respectively.\nSeveral other methods are used to decrease the level of harmful contaminations\nfrom the exhaust gases.<\/p>\n\n\n\n

In\nIndia\u2019s 67 years old automobile history, the year 2020 will add a crucial\nchapter as the Indian market will see the sale of BS-VI compliant vehicles. As\nper the honorable Supreme Court\u2019s order, the automobile manufacturing firms\nwill take a gigantic leap forward and shift to BS-VI standards, which are in\nparity with those in Japan, the US, and the European Union. <\/p>\n\n\n\n

BS-VI rules will demand a lot of modifications in the motor vehicle\u2019s technologies, from which the most significant one being the implementation of a mandatory feature for all vehicles, which is known as on-board diagnostics (OBD). An OBD device provides information to the vehicle\u2019s owner or the repair technician about the efficiency of the systems in the car. In India, It was first introduced in April 2010 for light-duty vehicles of all types, and updated thresholds were introduced with the BS-IV emission norms in April 2013. OBD requirements of BS-VI will be introduced in two stages, with BS- VI-1 OBD (preliminary OBD thresholds) applicable for all vehicles manufactured on or after April 1, 2020, as well as final thresholds (BS- VI-2 OBD) applicable from April 1, 2023. Values of the proposed threshold for BS- VI-1 OBD as well as BS- VI-2 OBD are analogous to preliminary as well as final Euro 6 threshold limits, respectively.<\/p>\n\n\n\n

The execution of advanced norms in India is a vital step as India, the third-largest emitter in the world after US and China, is a signatory to Conference of Parties (CoP) protocol on combating climate change according to which, by the year 2030, India has to decrease its carbon footprint by 33-35% from the level that is in 2005. The obligations carbon footprints have forced the country to shift directly to BS-VI norms by skipping the BS-V norms.<\/p>\n\n\n\n

The\nlevel of sulfur is the significant dissimilarity between BS-1V & BS-VI\nnorms. BS-IV grade fuels have 50 parts per million (ppm) sulfur; the BS-VI fuel\nsolely has 10 ppm sulfur. BS-VI can bring down PM by 80% in diesel cars. The\nnew norms will decrease the oxides of nitrogen by 70% from diesel cars as well\nas by 20% in petrol cars. DPF (Diesel Particulate Filter) is required to expel\nparticulate matters from the engine exhaust in heavy-duty engines. Hydrocarbon\nemissions from two-wheelers with gasoline engines are further controlled\nthrough the tightening of the evaporative emissions limit. Under the BS-VI\nnorms, all gasoline vehicle models are required to fulfill a 1.5 g\/test\nevaporative emissions limit, and no provisions of flexibility are included for\nmeeting tailpipe as well as evaporative emission limits. These steps will help\nto decrease total vehicle HC emissions.  <\/p>\n\n\n\n

DE102018108525A1<\/a> titled \u201cSystem for increasing the\ntemperature in an exhaust after-treatment system\u201d assigned to Ford Motor Co. discloses\na device for selective catalytic reduction (SCR) for the treatment of exhaust\ngas to reduce harmful emissions and decrease pollutants such as unburned\nhydrocarbons, oxides of nitrogen, carbon monoxide and particulate matter. This\nis done by increasing the rate of heating of exhaust gas flow by using the\ncomponent having an adherent ceramic coating on it that is exposed to the\nstream of exhaust gases and acts as a catalyst.<\/p>\n\n\n\n

US20180154897A1<\/a> titled \u201cMethod for reducing nitrogen oxide emissions of a diesel vehicle\u201d assigned to Robert Bosch GmbH discloses a method for decreasing oxides of nitrogen in diesel vehicles with the assistance of sensors and arithmetic unit that automatically finds out the required vehicle torque so as to prevent the exceeding of the threshold by the nitrogen oxides emission. In a nutshell, the automakers play a significant role in reducing the pollutants level from a vehicle with the applications of new technologies and inventions along with the optimization of engine\u2019s overall operation that is followed by the increase in vehicle\u2019s efficiency. Hopefully, the BS-VI vehicles will bring a drastic change and will play a crucial role in saving the environment which is eventually the actual purpose of the enforcement. <\/p>\n","protected":false},"excerpt":{"rendered":"
