Study Notes

BS-VI Implementation in India

  • BS-VI will be implemented in two stages in India:
  • Stage 1: Applicable for all vehicles on or after 11th April 2020
  • Stage 2: Applicable for all vehicles on or after 1st April 2023
  • Introduction of On-Board Diagnostics (OBD) - Stage 1:
  • O2 sensor
  • Engine Oil Temp Sensor
  • Malfunction Indicator Lamp
  • Introduction of Fuel Injection (FI)
  • Introduction of On-Board Diagnostics (OBD) - Stage 2:
  • Misfire Detection
  • O2 Sensor deterioration Detection
  • Catalytic converter monitor

Fuel Injection System

  • Basic Fuel Injection System:
  • ENGINE CONTROL UNIT - ECU
  • To calculate fuel injection volume and timing
  • Real Time Mileage Indicator –RTMI
  • Fuel Pump: To pressurise fuel
  • Pressure Regulator: To adjust fuel pressure
  • Fuel Injector: To inject fuel in throttle body
  • Sensors:
  • Throttle Position Sensor - TPS
  • Manifold Absolute Pressure Sensor - MAP
  • Intake Air Temperature Sensor - IAT
  • Crank Position Sensor - CPS
  • Engine Oil Temperature Sensor - EOT
  • Vehicle Speed Sensor - VSS

Emission System

  • Process:
  • Fuel + Air → Useful energy and Undesirable emissions
  • Emission Equation:
  • C8H18 + 12.5 (O2+3.76N2) → 8CO2 + 9H2O + 47N2
  • Air to Fuel Ratio:
  • Chemically correct ratio: 15.05:1
  • Actual ratio: 14.7:1
  • Effects of varying oxygen levels:
  • Less oxygen: CO and HC increase
  • Higher oxygen at higher temperature: NOx increases
  • Pollutants:
  • CO
  • HC
  • NOx
  • Particulate Matter (PM)
  • Evaporative Emissions

Automobile Pollution

  • Major Pollutants:
  • CO
  • HC
  • NOx
  • PM
  • Classifications for 2-wheeler emissions:
  • Exhaust Emissions
  • Evaporative Emissions

Chronology of EMISSION NORMS

  • Indian Emission Standards for Vehicles:
  • Euro 1 (2000)
  • Euro 2 (2005)
  • Euro 3 (2010)
  • Euro 4 (2017)
  • Euro 5 (skipped)
  • Euro 5 (2020)
  • BS-VI:
  • Introduced in 2020
  • Significant reduction in HC and NOx limits
  • NMHC introduced
  • Misfire detection and O2 Sensor monitoring introduced
  • Catalytic converter monitoring introduced

BS VI Emission Spec Details

  • Pollutants:
  • CO
