The objective of this study is to apply neat biomass fuel to a DI diesel engine and investigate the effect of in-cylinder gas flow and combustion on the deposit formation and the fuel dilution in lubricating oil. The study focuses on the low load combustion and emissions considering that low load exhaust contain much unburned fuels and the unburned fuels are the source of the deposit formation and...
We investigated the super-oscillation by radially polarized Laguerre-Gaussian beams in tight focusing condition. We experimentally demonstrated that this super-oscillation is applicable for confocal laser scanning microscopy to greatly enhance the spatial resolution.
This paper describes a non-contact heart rate monitoring system using a microwave Doppler sensor. It can achieve better usability than conventional heart rate sensors, which require direct skin contact. The objective of this work is to detect an instantaneous heart rate using this non-contact system. The instantaneous heart rate can contribute to prevent heart disasters and to detect mental stress...
Quantitative measurements of local fuel concentrations were conducted in a direct-injection hydrogen spark-ignition research engine using the spark-induced breakdown spectroscopy (SIBS) technique. For SIBS measurements, a new sensor was developed from a commercially available M12-type spark plug with no major modifications to the electrodes. The new plug sensor showed better durability and required...
