In this research work, experimental studies have been carried out on emission and performance characteristics of a pre-mixed charge compression ignition (PCCI) setup using cotton seed bio-diesel blends. Port fuel injection strategy is the basic concept of PCCI engine. Bio-diesel was used in PCCI engine for further reduction in emissions. Bio-diesel was produced by trans-esterification process. Cottonseed oil (CSO) was selected for biodiesel production. The experiment was conducted with PCCI setup using diesel-diesel, blends of bio-diesel with varying percentage from 10% to 30% by volume. The experiments were conducted in PCCI setup with bio-diesel blends and compared with conventional diesel mode of operation. The experimental results showed that there was decrease in carbon monoxide (CO), nitrogen-oxide (NOx) and increased hydrocarbon (HC) emissions. There was a reduction in smoke emission and increase in brake specific fuel consumption (BSFC) with increase in blends of bio-diesel in PCCI modes.
