Abstract: The project focuses on reducing harmful automobile emissions through a water injection system integrated into the exhaust manifold. The proposed setup consists of a water tank, control valve, heat- resistant pipes, honeycomb pads, and nozzles. Water is sprayed onto the heated honeycomb pads, reducing exhaust gas temperature and converting toxic gases such as NOx, CO, and HC into less harmful forms. This simple, cost- effective modification shows significant emission reduction while maintaining system efficiency. Experimental results demonstrate notable decreases in exhaust temperature and emission concentration, making it an eco- friendly and retrofit-compatible solution for small engines.

Keywords: Emission Control, Exhaust Manifold, Water Injection, Honeycomb Pad, Pollution Reduction.
