Three ranges of variables are defined as low, normal and high for injection of little fuel, faultless operation and too much injection respectively. Also, for other variables in exhaust gas content, the same ra
The current practice of using micro-EDM drilling for fabricating fuel injection nozzles is limited in terms of the hole size that it can produce effectively and the length of time needed to drill. In addition, the tooling cost is also high (14). Attempts have been made by a number of re...

Thin copper substrates with high accuracy are highly required in precision physical experiments. However, even using double-sided lapping, the flatness is still limited due to the accuracy of lapping plate, process vibration and so on. Hence, as a subsequent process, this paper employs magnetorheolo...

It shares many of the favorable attributes of other ceramics such as high hardness, high strength, and high stiffness. It also has excellent dielectric properties. It is commonly used for electrical 130 PROCEEDINGS OF THE TWENTY-SECOND INTERNATIONAL PUMP USERS SYMPOSIUM • 2005 insulators, wear ...
In a case in which the writer was involved many years ago, a small tube leading to a pressure gauge cracked by fatigue due to vibration caused by a nearby pump. The crack in the tube allowed ethane to escape and the ethane concentration then built up in the pump room until it reached ...
Mechanically compressing peat to remove water has been practiced in Europe for generations, to speed up the solar evaporative drying of this fuel. However, commercialisation of this technology has been limited by the high pressures (10-50 MPa) and residence times (hours) required (Sharp, 1982)....
