JOURNAL FREE ACCESSIn view of the fact that the consumption of motor gasoline, petrol engine Fuel and aviation gasoline in Japan has recenthy been increasing enormously, some desi-rable properties for these fuels Should be checked.
If would encounter some obstacles and difficulties to apply the product specification set up in foreign countries to our situations. The first thing we shonld do, therefore, is to conduct all sorts of experimental performance tests on the said fuels applying them to various types of engine universally used in Japan in order to find out desirable prorerties to meet actual conditions. Then a decision should be made on suitable properties, taking account of pressent installed refinery facilities, possible expansions of these facilites and results of our research in future.
In using the fuels having some desirable properties gained the tests, it is important to know appropriate conditions for using and adjustment of the engine in order to obtain 100% of the effects of the right properties.
For your reference, 1 should like to precent you some research materials and a portion of our performance test results.View full abstractDownload PDF (1432K) -
Takeshi Kamatani1955 Volume 34 Issue 1 Pages 10-16
Published: January 20, 1955
Released on J-STAGE: June 28, 2010
JOURNAL FREE ACCESSDifference between diesel and gasoline engine, safety and economy of diesel fuel, significance of diesel engine to industry, traffic, and national defence, and the necessity for popularising use of diesels in those nations not having rich petroleum resources-such as German and Japan-was explained.
Next, classifications of diesel fuels by their use and viscosity, common nature of diesel fuels used in engines and special properties required before completion of the injection stage and after commencement of the combustion stage were refered to. A full explana-tion was given as to the relation between fuel injection and fuel viscosity.
Also, the characteristics of high viscosity fuel oil used in low-speed marine diesel en-gine and essential points in handling such viscous fuel were outlined.
Lastly, diesel fuels used in U. S. A. and that of our country was discussed.View full abstractDownload PDF (1379K) -
Akira Wakana1955 Volume 34 Issue 1 Pages 16-23
Published: January 20, 1955
Released on J-STAGE: June 28, 2010
JOURNAL FREE ACCESSThe author reviews the recent topics of lubricating oils, which are consider-ed important and interesting. On turbine oil, the use of additive improves its performance excellently and good quality of turbine oil can be manufactured from Kuwait crude oil by using additive; on insulating oil, Japanese Industrial Standard test on oxidation stability and results of use of regenerating oil are mainly described; on motor oil, evaluation of Heavy Duty type oil is described. Morever, he discusses the effect of extreme pressure additives and its working mecha-nism, and explains the new calculation table of Redwood viscosity to kinematic viscosity.View full abstractDownload PDF (1687K) -
Toyosaburo Dan1955 Volume 34 Issue 1 Pages 23-32
Published: January 20, 1955
Released on J-STAGE: June 28, 2010
JOURNAL FREE ACCESSThe purpose of this review gives the outline of lubricating greases and is to show the basic principle about proper selection and use of them. Lubricating greases were devided into four classes, that is, water-resistant type, water-soluble type, multi-purpose type and synthetic grease, and each characteristic was outlined. Then, their physical and functional properties, structures, additives, rust-preventing behaviors and fillers, as well as the value and significance of physical testing were described. Finally, the lubricating action of lubricating greases in bearings was briefly discussed.View full abstractDownload PDF (2981K) -
ON THE SECONDARY REFERENCE FUELRyo Kato1955 Volume 34 Issue 1 Pages 40-49

Released on J-STAGE: October 21, 2011
JOURNAL FREE ACCESSPrimaly reference fuel for testing cetane number of diesel fuels has so far been supplied by imports. however, in order to obtain this fuel in our country, a number of studies have been made, as a result of which it has been confirmed that molybdenum trisulfide is most suited for the fuel as catalyst which gives hydrocarbon having carbon number equal to that of primary fatty acid if molybdenum trisulfide is hydrogenerated by means of higher fatty acid and its ester used as raw material.
By means of spermaceti used as raw material, the effect of reaction conditions such as reaction temperature and adding quantity of catalyst on cetane number has been clarified. Spermaceti which is consisted of cetyl palmitate was considered suitable as raw material for manufacture of cetane, but it failed to produce desirable quantity of pure cetane because it is subjected to side chains because of its having straight chains, however, as it was found that the secondary reference fuel of cetane number 100 could be obtained from spermaceti to the required quantity, we have succeeded to industrialize it as the reference fuel of cetane number 100.
Furthermore, we succeed in obtaining the secondary reference fuel of cetane number 100 from hydrogenerated oil made from animal, vegetable and natural fats, sperm whale, soyabean oil, rice bran oil and Japan wax, on which further report will also be made.View full abstractDownload PDF (1664K) -
