In order to utilize bio-alcohols as the fuel for diesel engines, combustion characteristics of alcohol blended with gas oil were compared between ethanol and n-butanol in a direct injection diesel engine. In the case of the same cetane number betw...
In order to realize a premixed compression ignition (PCI) engine by utilizing bio-alcohol, combustion characteristics of bio-alcohol blended with gas oil were compared between ethanol and n-butanol in a diesel engine. The effects of the ethanol bl...
Utilization of bio-ethanol as an alternative fuel for diesel engines is one of the effective strategy for suppression of global warming because of its high thermal efficiency. In order to realize a premixed compression ignition (PCI) engine by uti...
A laser 2-focus velocimeter (L2F) has been applied for measurements of velocity and size of droplets in the dense region of diesel spray. Investigated was the fuel spray injected intermittently into the atmosphere from an injector nozzle with the ...

In order to realize a premixed compression ignition (PCI) engine, the effects of bioethanol-gas oil blends and exhaust gas recirculation (EGR) on PM-NO. x trade-off have been investigated focusing on ignition delay, premixed combustion, diffusion ...
A low solidity cascade diffuser (LSD) shows features of a wide operating range and a high pressure ratio, however, a high level of noise. The first objective of the present study is to show that the noise can be reduced effectively without deterio...
This paper deals with the effect of the blade leading edge location of low solidity cascade diffuser (LSD) on noise and diffuser performance in a centrifugal blower. The noise of the vaneless diffuser, varied little in a wide flow rate range, on t...
In order to investigate the distribution of droplet sizes in the core region of diesel fuel spray, instantaneous measurement of droplet sizes was conducted by an advanced laser 2-focus velocimeter (L2F). The micro-scale probe of the L2F is made up...

In order to investigate the effect of transient needle opening on early stage of spray behavior, simultaneous measurements of velocity and size of droplet were conducted by a newly developed laser 2-focus velocimeter (L2F). The micro-scale probe o...
Recently the field survey, the model observation, and the numerical simulation are reported for countermeaserment of pollution in Omura Bay. It's seems that the best way for the improvment of pollution in Omura Bay is to introduce the new sea wate...
In this paper, the diffusion of pollution is simulated in Omura Bay, by the electric computer for the case that the new sea water is introduced in Omura Bay. The results of tidal simulation is reported in the other paper. Here, three different ana...
