Today, nations are in the path of low-emission transformation mandating stricter emission norms with periodic revisions. With the expected introduction of Bharath Stage VI (BS VI) for two wheelers in India by 2020, limitation in primary pollutants namely - Carbon Monoxide (CO), Total Hydro-Carbons (THC) and Nitrogen Oxides (NOx) are reduced by 50%, 75% and 85% respectively in comparison to the existing Bharath Stage IV. The original equipment manufacturers (OEMs) are identifying measures to improve the overall efficiency and raw emissions from the engine through strategies like multi-spark configurations, improved charge induction concepts, liquid cooling, lean combustion etc. With end user demands for performance, low end torque, high power to displacement ratio, quick acceleration and fuel efficiency, the balance with the emission regulation is expected to be challenging.
