Hydrocarbon Pollutant Emitted From a Diesel Engine Fueled With Biodiesel and Diesel Fuel No.2

Abstract

In this study, effects of biodiesel in fuel mixture (biodiesel and diesel fuel No.2) on hydrocarbon (HC) pollutant that emitted from a 4 cylinder water cooled diesel engine were studied. The data were collected by the standard experiments on a direct-injection diesel engine. Results showed that by the use of biodiesel, HC emissions decreases 30 to 85% than net diesel fuel No.2 Also results indicated that by increasing rpm of the engine emission of HC decreases continuously. On other hand HC emissions are higher at low engine loads.
