Optimized Exhaust After-Treatment System Solution for Indian Heavy Duty City Bus Application - The Challenges Involved and the Right Approach to Meet Future BS VI Emission Legislations and Real World Driving Emissions
The vehicular pollution and emission levels are alarmingly increasing in India. The metro and urban cities are worst hit by the gaseous and particulate emissions produced by internal combustion engine powered vehicles. Following the trend from other developed countries, Government of India (GOI) has decided to migrate from existing BS IV legislation directly to BS VI legislation from April 2020 all across India. This migration in emission legislation took almost 10 years to be implemented in European Union (EU) countries. However, for India, the targeted implementation time is just 3 years, making it an uphill challenge for all the vehicle manufacturers. City bus is one such applications, which run mostly within the city and currently are powered by conventional Diesel engines. The vehicle manufacturers should focus on finding an optimized solution for meeting the future emission legislation in true sense.
