Abstract: (1206 Views) |
| In this paper, first the performance of the present Four-stroke, 6-cylinder and in-Line marine diesel engine with direct fuel injection system and compression ratio 14.8 and turbocharger pressure ratio 3.4, is simulated and validated in Diesel-RK software and then performances of various biodiesel fuels; B20 SME, B40 SME, B100 SME and Diesel No.2 are compared and due to 13.61% reduction of Bosch Smoke Number and only 2.46% reduction of engine power; B20 SME is sugested as the best alternative biodiesel fuel for common diesel fuels. Also with surveying the effect of the exhaust gas recirculation system, results show that 5% exhaust gas recirculation could prevent up to 39% of NOX production per cycle, so for minimum pollutants emission of Marine Diesel engines, the use of EGR system is recommended. |
