Investigation of the effects of camelina sativa biodiesel and eurodiesel blends on vehicle performance and emissions

Studies have been conducted on improving engine performance, reducing environmental pollution caused by vehicles, and using alternative fuels. In the study, tests are carried out in a laboratory environment to check whether the engine has reached the intended use. Testing of internal combustion engines is crucial to research and teaching, trade and environmental pollution. Depending on the purpose of the test, the type and duration of vehicle tests will vary. Automobile manufacturing companies and research units will conduct a series of scientific and long-term tests in the vehicle development process. Thanks to engine and vehicle tests under different operating conditions, the measured values such as economy, power, moment, emission are compared with performance curves. In this study, biodiesel was obtained from crude camelina sativa oil using the transesterification method. Camelina sativa biodiesel was mixed with Eurodiesel at the rate of 7% (B7), 20% (B20) and 50% (B50). Vehicle performance measurements of biodiesel-Eurodiesel blends were made on a vehicle with four-stroke, four-cylinder, Common-rail fuel system, turbocharged and water-cooled engine using a chassis dynamometer. Vehicle performance and exhaust emissions were measured at different speeds during the vehicle chassis dynamometer test. While the highest moment value was obtained at 80 km/h in B7 fuel, the maximum engine power was obtained in B7 fuel at 160 km/h. Average engine power and maximum engine torque of B100 fuel decreased by 3,28% and 10,21% compared to Eurodiesel fuel. As the rate of biodiesel increased, specific fuel consumption increased. The highest specific fuel consumption was obtained with 91,6 g/kWh in B100 fuel at 160 km/h. The average specific fuel consumption of B100 fuel increased 38,5% compared to Eurodiesel fuel. When we look at the results of exhaust emission measurements, it is seen that camelina sativa biodiesel and fuel mixture decreased CO, CO2 and HC values compared to Eurodiesel fuel, but increased NOx values.
