Over the period of time, emission standards
have become stricter and stricter. The adverse effect of
greenhouse gases generated by not only industries but
also automobiles have become a major concern for
addressing as it produces ill health to all human beings.
The tremendous growth in the automobiles and related
industries have reached to an alarming level and
necessitates engineers to work harder and harder to
devise systems which can reduce harmful emissions to
an acceptable level. Pre-Mixed Charge compression
ignition (PCCI) is one of the technological methods of
achieving complete combustion in an internal
combustion engine which contribute further in reducing
emissions. PCCI engine has been proved as a better
choice in the present scenario where emission standards
are degrading day by day making the environment
dangerous for sustenance of life.
