Cylinder to Cylinder Deviations in Combustion and Emission at Idling in DI Diesel Engines with Pilot Injection
Pilot injection in DI Diesel Engines is a very effective method reducing nitrogen oxides and noise. However the injection behavior of small quantities of pilot fuel is unstable,and the cylinder-to-cylinder deviations in injection mass and spray development occur in multi-cylinder direct injection diesel engines. This study investigates the correlation between cylinder-to-cylinder deviations in spray development and combustion and emissions when the pilot injection was applied at idling. It was found that the cylinder-to-cylinder deviations in spray behavior are not the sole reason for the deviations in combustion and emission, but that peculiar conditions to a cylinder such as air movement and in-cylinder carbon deposits also play a role. In this study the HC components in the exhaust gas with and without pilot injection was investigated, and it is shown that deviations in combustion with pilot injection result in deviations in low carbon component emissions and in the rate of pressure rise which is responsible for exhaust odor and engine noise.application/pdfjournal articl
Perpendicular Magnetic Anisotropy in Amorphous Rare Earth-Transition Metal Films
application/pdfExperimental studies on the perpendicular magnetic anisotropy in amorphous TbCo prepared by rf sputtering have been carried out and the results obtained have been compared with those in other amorphous rare earth-transition metal films. it has been found that the perpendicular anisotropy of TbCo films greatly depends on a negative bias voltage applied to the substrate during sputtering. Because of their large magnetostriction, the anisotropy results from the planar stress due to the substrate constraint occupies considerably part in the whole perpendicular anisotropy in TbCo films. Annealing for one hour at 300℃ destroys the perpendicular anisotropy almost completely. Magnetostriction plays an important role in the magnetization process in amorphous films without crystalline anisotropy. However, few studies have been done on magnetostriction in amorphous films. Therefore, a cantilever capacitance apparatus has been set up for measuring the magnetostriction constant. It has been found that using a standard Fe0.4Ni0.60 film for calibration, this apparatus is accurate enough and very useful.departmental bulletin pape
