Product Training Fuel Injection & Emission Basic Fuel Injectio n Emissio System n Fuel Injection System BS-VI 2 Emission System Process Input Out put Fuel + Air -Useful -Undesirable Fuel=C8H18 Fuel Air Air=O2+3.76N2 Emission Throttle Electrical SI ENGINE Body. Power POWER TO DRIVE MOTORCYCLE Fuel Injection System BS-VI 3 Emission System C8H18 +(O2+3.76N2) CO2+H2O+N2 C8H18 + 12.5 (O2+3.76N2) 8CO2+9H2O+47 N2 Molecular Weight of Carbon=12 , C8=96 Molecular Weight of Hydrogen =1 , H18=18 Total Molecular weight of fuel=96+18=114 Molecular Weight of O=16 , 02=32 Molecular Weight of Nitrogen =14 so N2=28 Hence Molecular weight of air= 12.5 (O2+3.76N2)=12.5(32+3.76*28)=1716 Hence the chemically correct ratio of Air to Fuel=1716/114=15.05:1 As Fuel also includes some other additives hence it is 14.7:1 In case of less oxygen in input –CO & HC will more in output In case of Higher oxygen at higher temperature –NOX Less methane in fuel- NMHC (Non Methane hydrocarbon) Unburnt particles =pm(Particulate Matter) From Fuel Tank & breather tube –Evaporative Emission Fuel Injection System BS-VI 4 AUTOMOBILE POLLUTION Gasoline vehicles : -Major Pollutants : CO, HC, NOx Vehicles with lean burn engines : -Major Pollutants : NOx Diesel Driven Vehicles : -Major Pollutants : PM, Nox “Particulate Matter : Main Concerns” Major classifications for 2-wheeler emissions are as follows: Exhaust Emissions Muffler Evaporative Emissions From Fuel Tank Carburetor Fuel Injection System BS-VI 5 Chronology of EMISSION NORMS Indian Emission Standards For Vehicles Standard Reference Year Region Emission Details India 2000 Euro 1 2000 Nationwide Mandatory Catalytic Converter , Introduce Unleaded fuel in market 2001 NCR : Mumbai As the number of vehicles Kolkata : Chennai 2003.04 NCR:13 Cities increased, BS2 introduced Bharat Stage II Euro 2 2005.04 different emission standards for Petrol & Diesel Engines with Nationwide reduced acceptable limits 2005.04 NCR:13 Cities Introduced separate HC & NOx level for Bharat Stage III 2010.04 Nationwide Euro 3 Petrol Engines and separate NOx for Diesel Engines 2010.04 NCR:13 Cities Introduced evaporative emission norms Bharat Stage IV Euro 4 2017.04 Nationwide , significant reduction in limits Bharat Stage V Euro 5 2019.04 Skip Skipped Bharat Stage Euro 5 2020.04 Entire Country Significant reduction in HC & NOx , VI-OBD1 (proposed) NMHC introduced Bharat Stage Misfire detection , O2 Sensor & 2023.04 VI-OBD2 Euro 5 (proposed) Entire Country Catalytic converter Monitoring introduced 13 Cities:-Mumbai,Kolkata,Chennai,Bengaluru,Hyderabad,Ahemdabad,pune,Surat,kanpur,Lucknow Sholapur, Jamshedpur and Agra Fuel Injection System BS-VI 6 India to SKIP BS-V India is a nation with 10 most polluted urban cities of the world. Origin of NOx, SO2 & particulate is inflicting significant damage on individual’s wellbeing. Ex- In Delhi in 2014, the PM2.5 level is more than 6 times the endorsed levels by WHO. Being part of the Paris Climate Agreement held in Oct’16, India committed to cut down carbon impression by 33-35%. This justified the requirement for a “STRICTER STANDARDS” that could diminish the outflows significant to aligned with PCA. BS-VI is inline with Euro-V standard.
