Biodiesel is an alternative diesel fuel that can be produced from different kinds of vegetable oils. It is an oxygenated, non-toxic, sulphur-free, biodegradable, and renewable fuel and can be used in diesel engines without significant modification. However, the performance, emissions and combustion characteristics will be different for the same biodiesel used in different types of engine. In th...
farmers are now more interested in application of weed control methods and tools with less environmental side effects. flame weeding using propane gas is an approach with almost no any chemical residue on the soil and plant surfaces or underground water. in this research, a flame weeding machine with the ability of uniform and also discrete flaming was developed and evaluated in laboratory and ...
the significant consumption of gas in the world results in the emission of greenhouse gases into atmosphere. abadan refinery has always been the biggest and oldest oil refinery in the middle east and has a variety of refined products. after six months of collecting data about pollutant concentration emitted from a stack of old furnaces of units 75 and new unit 200, the emission factor of the po...
An experimental investigation on engine performance, emissions, combustion and vibration characteristics with coconut biodiesel fuels was conducted in a high-pressure common-rail diesel engine under five different load operations (0.17, 0.34, 0.52, 0.69 and 0.86 MPa). The test fuels included a conventional diesel fuel and four different fuel blends of coconut biodiesel (B10, B20, B30 and B50). ...
To fully utilize the fuel reduction potential of a hybrid powertrain requires a careful design of the energy management control algorithms. Here a controller is created using mapbased equivalent consumption minimization strategy and implemented to function without any knowledge of the future driving mission. The optimal torque distribution is calculated offline and stored in tables. Despite onl...
This work was one of the tasks of the Manufacturing2Client project, whose objective was to develop a frontal deflector to be commercialized in the automotive industry, using new project and manufacturing methods. In this task, in particular, it was proposed to develop the ability to predict computationally the aerodynamic influence of flow in vehicles, in an effort to reduce fuel consumption in...
Reducing fuel consumption is a major goal for the aviation community due to environmental concern and fuel price uncertainty. The Federal Aviation Administration (FAA) is currently developing and implementing Air Traffic Management (ATM) technologies to ensure reliable operational performance that is robust to delays caused by congestion and weather. These technologies will reduce planned and u...
The environment has recently led to very severe regulations on fuel consumption and exhaust emissions. I propose a scheme to minimize rate of fuel consumption for a direct fuel injection engine used by combination with a continuously variable transmission. Target values for the engine and the transmission which minimizes fuel consumption ensuring driving performance is calculated based on the n...
