A review on performance and emission characteristics of a diesel engine fueled with gaseous & liquid fuels

Abstract

There is a growing need for alternative fuels because of growing concerns about the environmental harm caused by the usage of fossil fuels. In an effort to reduce energy use, a number of research have been conducted. It is widely accepted that biofuels derived from biomass are a viable alternative to petroleum-based fuels. Biogas, a biomass-derived fuel, is suitable for use in internal combustion engines due to its superior air mixing ability and clean burning qualities. In comparison to other secondary fuels, biogas is less costly and emits fewer pollutants because of anaerobic digestion of a variety of organic materials like kitchen trash, agricultural waste, municipal solid waste and so on, being the process through which it is produced. As part of this investigation, biogas usage is reviewed in case of dual fuel engines. Diesel & biogas dual fuel diesel engines have been proven to emit less hydrocarbons (HC), smoke and particulate matter than conventional diesel engines. A complete literature study is conducted for establishing emission, combustion & performance characteristics for biogas combustion for CI engines.
