Data Source: ARAI Emissions Handbook ©pManifold EV Academy 11 Tailpipe GHG Emissions of IC Engines Every fossil fuel and even most of the bio fuels are hydrocarbons. Combustion chemical reaction of any hydrocarbon fuel is given by the following generic equation… CmHn + (m + n/4)O2 = mCO2 + n/2H2O Emission of carbon dioxide is inevitable part of IC engines (except for hydrogen IC engine) Carbon dioxide in atmosphere reflects back the heat radiated by earth, consequently trapping it in the atmosphere and causing global warming At higher ambient temperatures, the solubility of carbon dioxide in seawater is also high, turning the oceans more and more acidic, thereby endangering aquatic life Aquatic life is one of the primary source of atmospheric oxygen ©pManifold EV Academy 12 Tailpipe GHG Emissions: Regulations Evolution Each manufacturer has its individual annual target, calculated based on the number of vehicles sold in the region to which regulation applies. The following formula prescribed to calculate the CO2 targets… Specific emissions of CO2 = E0 + a x (M – M0) E0 is reference mass vehicle max CO2 emissions = 95 g/km M is the average mass of the manufacturer’s fleet (kg) M0 is the reference mass = 1379.88 kg a is 0.0457 Corporate average CO2 targets will soon become unrealistic to meet without electric vehicles in the portfolio ©pManifold EV Academy 13
