Experimental Study on Effect of Water Ingestion into Inlet Manifold on Performance and Emissions in Compression Ignition Engine

Rajmohan.N , Dr. Swaminathan M. R

The performance of a diesel engine depends mainly on mixing of the fuel and air in the combustion chamber. The diesel engine suffer from significant generation of nitric oxide and particulate matter emission due incomplete combustion. As the fuel is injected directly into the combustion chamber in conventional diesel engines, spatial distributions of air-fuel ratio vary widely from rich to lean in combustion chamber. The NOx is formed in stoichiometric zone and smoke is generated during diffusion combustion period where the combustion rate becomes slower. One of the effective method to reduce oxides of nitrogen and particulate matter emissions simultaneously is to reduce the intake charge temperature in diesel engine. Therefore in the present study, the effect of water injection into intake air on performance and emission characteristic of single cylinder CI engine are carried out at different load and constant speed, with variable water to diesel ratio by mass. The water is injected into intake air by an elementary carburettor.
