Computational and Experimental Analysis of Fuel Consumption of a Hybridized Vehicle

In this present work, experiments were conducted on a VCR Diesel engine with diesel, Neem oil biodiesel and Di-ethyl ether mixed with neem oil biodiesel. The performance and emission characteristics were evaluated and compared. The study shown that the Brake thermal efficiency increased and the brake specific fuel consumption reduced with B10 blend of neem oil biodiesel compared to diesel. The emissions of CO, CO2 were reduced but HC and smoke were increased with the use of biodiesel than diesel. The addition of Diethyl Ether (DEE) further improved the performance and decreased the emissions of CO and CO2 of the engine at B20DEE20 blend compared to other blends of biodiesel and diesel.

Abstract. The paper examines the workload perceived by air traffic control officers (ATCOs) and pilots during continuous descent operations (CDOs), applying closed- and open-path procedures. CDOs reduce fuel consumption and noise emissions. Therefore, they are supported by airports as well as airlines. However, their use often depends on pilots asking for CDOs and controllers giving approval and directions. An adapted NASA Total Load Index (TLX) was used to measure the workload perception of ATCOs and pilots when applying CDOs at selected European airports. The main finding is that ATCOs’ workload increased when giving both closed- and open-path CDOs, which may have a negative impact on their willingness to apply CDOs. The main problem reported by pilots was insufficient distance-to-go information provided by ATCOs. The workload change is important when considering the use of CDOs.
