Electrinic Fuel Injection (EFI) a system that supplies fuel from the tank electronically with mixture of air suits needs so vehicle power remains maximum minimal consumption to produce environmentally friendly emissions. The injection is an innovation step being developed and applied motor vehicles today. purpose study was find out characteristics 2007 Honda Jazz I-DSI engine using parameters t...

In order to increase the intensities of the ion beams in the JINR-Dubna superconducting Synchrotron NUCLOTRON, to raise their energies and to inprove their quality a booster synchrotron is under design. This booster synchrotron needs some kind of multiturn injection to store particles. The multiturn injection with betatron stacking is simulated in this paper. The simulations reveal the optimum ...

Performance evaluation of Internal Combustion Engines (ICEs) and setting different emission standards has manifested the importance of pollution reduction as well as the optimal fuel consumption of these engines. Accordingly, the Engine Management Systems (EMS) are utilized which resulted in optimizing the power alongside the decrease in pollutant emission, through preparing the appropriate air...

This study investigates how high levels of exhaust gas recirculation (EGR) combined with certain fuel injection strategies and energy recovery systems affect diesel engine emissions and fuel economy. The key test apparatus was a John Deere 4.5L diesel engine which was modeled using the computer-based engine simulation tool GT-Power. The conclusion was made that utilization of high EGR levels (3...

one way to increase the shelf life of agriculture products is using of controlled atmosphere storages. in order to obtain the controlled gas components, an equipped cold store with cooling system and atmosphere controller system designed and constructed. the injection of co2, o2 and n2 were controlled automatically into the store by programable logic control (plc). the store was a laboratory re...

CMOS device lifetime is determined at tempcratures of 77 K, 150 K, and 218 K. Due to enhanced hot carrier degradation, lower operating voltages are necessary at lower tcmperatures. A novel, two-slope lifetime behavior is observed at 77 K, emphasizing the need to stress devices near the desired operating voltage. The dominant degradation mechanism depends on the temperature and drain bias. Above...

This topic introduces the concept of Hot Swapping DC power buses and why hotswapping has become a mainstream requirement, particularly in the telecommunications industry. Several methods of implementing hot swap will be provided along with the pros and cons of each method. Finally, a hot swap design utilizing a Hot Swap Power Manager will be presented for a typical -48V telecom
