Performance and Emission Characteristics of Jatropha and Dimethoxy-Methane Fuel Blends with EGR in Single Cylinder Water Cooled CI Engine
Main Article Content
Abstract
The number of vehicles on the road has increased by a factor of ten in recent years. As a result of the pollutants emitted by these vehicles on and off the road, ambient air quality has deteriorated significantly. It also increases greenhouse gas emissions as more CO2 is discharged into the atmosphere. As a result, researchers are concentrating on reducing fuel usage and emissions. Because fossil fuel stocks are decreasing, there is an increasing demand for alternative energy. Alternative fuels such as biodiesel and ethanol, which are made from vegetable oil and sugar molasses, are both renewable and environmentally friendly. Blending fuels to increase the combustion qualities of fuel has recently become a viable alternative. A single-cylinder, water-cooled diesel engine with a rated output of 3.7kW at 1500 rpm was used in the tests. We tested diesel, biodiesel and biodiesel with a 10% DMM blend with and without EGR and biodiesel with a 20% DMM blend with and without EGR. Biodiesel with DMM blends has lower thermal efficiency, produces less smoke and emits more NOx. NOx emissions were lowered whereas smoke emissions increased after EGR was used.
