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

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:
