Performance And Emissions Characteristics Of Water Ingestion Into Inlet Manifold In CI Dl Engine

摘要

The objective of this work is to analyze the effect of water ingestion through a simple carburettor on the performance and emission parameters of a four stroke single cylinder constant speed diesel engine. Experimental work is carried out in a diesel engine running at a speed of 1500 rpm with varying water to diesel ratio (W/D) of 0.2, 0.3 and 0.4. The result indicated a significant reduction in NOx and smoke emissions. Emissions from diesel engines play a significant role in human health and environmental ecological balance. The result of the project indicates a reduction in NOx by 60% and smoke by 22% with water to diesel ratio of 0.4 compared to neat diesel. This reduction is due to the effect of water spray in heat release and cylinder pressure. There was a marginal drop in thermal efficiency, the HC and CO emissions are increasing with water ingestion.
