ABSTRACT
The advent of stringent emission norms and depletion of fossil fuel resources led the engineers to work out new combustion technologies to substantially reduce harmful emission and to improve the overall efficiency of an IC Engine. In this experiment we analyze the performance and emission characteristics of HCCI engine operating in premixed charge compression ignition (PCCI) mode assisted with a secondary pilot injector as combustion initiator. Homogenous charge compression ignition (HCCI) is a clean and efficient combustion process. Experiments were conducted in a modified single cylinder water-cooled diesel engine, employing our conceptual system known as transient state fuel induction provided by Southern Argo Engine Private Limited, Chennai. Here we use diesel, petrol and bio-diesel (Jatropha) as the fuel at different mixing ratios. Variable valve actuation (VVA) has been proven to extend the HCCI operating region by giving finer control over the temperature-pressure-time history within the combustion chamber. The observations are proved to have increased in brake thermal efficiency with reduced emissions.
