Combined with the characteristics of vehicle operation, a torque distribution control strategy based on logic threshold method for a series-parallel hybrid electric bus is proposed to improve the vehicle's fuel economy. And the simulink model of this strategy is built. Then the simulation is completed under the selected cycle condition. Compared with the real vehicle test data, the control stra...

due to the deployment of military units in different provinces and different lands and areas in iran and doing many different missions, the amount of fuel consumption of vehicles is not only identical but also different. since the precise measurement of fuel consumption and estimating its needs are important, the factors affecting fuel consumption, military units, including temperature, humidit...

The modified out-in fuel management strategy was applied to the core loading design for the first four cycles of the Bushehr (Iran-1) KWU designed Pressurized Water Reactor (PWR). The minimum peak-to-average power density was chosen as the objective function of the optimization process. Lattice homogenization and group constants generation were performed by using the LEOPARD computer code. For ...

In this study, we estimate variable fuel costs and total energy consumption for grid-powered electric cars using eight-year forecasts of cost per kilowatt hour for US national data coupled with real data distributions derived by daily electronic tracking the performance of a single Nissan Leaf located in Texas. These fuel costs are estimated based on a stochastic driving distance, then costs ar...

field capacity, fuel consumption and drive wheel slippage in massey ferguson (mf399) tractor with standard and liquid ballasted (630 kg) axle load and at 4wd mode was evaluated and compared. the tests were conducted at the experimental station, college of agriculture, shiraz university, in a field with clay loam soil at average moisture content of 18% d.b. the experiment was of a randomized com...

concrete is one of the most utilized construction materials in the world. nowadays, nano silicate usage due to its special property attracted considerable attention. on this basis, studying its environmental functions is an essential issue. accordingly, the behavior of normal concrete and the one with nano silicate were compared via taking advantage of life cycle assessment (lca) method in this...

Abstract Simulation studies can be used to determine the fuel consumption and carbon dioxide emissions of city buses. The operating conditions such vehicles are characterised by a very high variability vehicle speed due large number stops along route bus. During testing, driving cycles replicate real-world achieve repeatable test conditions. Such cycle is profile represented as function time or...

The competition to deliver fuel e cient and environmentally friendly vehicles is driving the 1 2 Submitted to Journal of Dynamics Systems, Measurement, & Control automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal co...
