Performance analysis of a 4-stroke SI engine using CNG as an alternative fuel

The research on alternative fuels has become essential due to depletion of petroleum products and its major contribution for pollutants. In the present work, Compressed Natural Gas (CNG) has been introduced as an alternative fuel to overcome the above problems. Of the higher compression ratio, higher octane number, the CNG is used to allow the combustion without knocking. The emission characteristics of HC and CO are better for CNG compared to petrol. In this work experimental investigations have been carried out pertaining to the engine performance and exhaust emissions of a single cylinder 4-stroke air cooled type Bajaj-Kawasaki engine
