Abstract

Water in vapour form was injected into the intake manifold of a diesel engine to increase the relative humidity of the charge in an effort to reduce emissions. The test engine was operated under ambient conditions at various engine speeds with and without the use of a humidifier and the engine performance and emission parameters were measured. The relative humidity of the charge decreased with increasing engine speed because the humidifier produced a constant rate of water vapour. This increase caused a slight decrease in the engine power and torque, but there was a significant reduction in Nitrogen Oxides (NOx) emissions.
