Electricity is a key energy source today, with rising household use of heavy loads like ACs and washing machines. Unlike industrial loads, which are balanced and follow fixed patterns, household loads are increasingly non-linear due to electronic devices and inverter technology. This leads to harmonic disturbances in the power system. The proposed system aims to implement a Shunt Active Power Filter using the PI technique to mitigate harmonics and noise from non-linear, unbalanced, and mixed loads.

Diesel engines are playing a vital role in the field of transportation and power generation. In the present world, much research is going on in the field of renewable energy to replace conventional sources of energy. But it is not very easy to replace diesel engines with other engines when power and reliability are the factors that matter. The emissions from diesel engines are very harmful to the environment and to human health. The major emissions are NOx and smoke which need to be controlled in an effective manner. This experimental investigation was carried out to find out suitable additives for reduced emissions without altering the performance of diesel engines. For that purpose, detailed experiments were conducted with different sets of nitromethane-n-butanol-diesel blends.
