Show the diesel oil engine As there is at this time great promise and every reasonable assurance of the production due tion of crude pert oleum in commercial quantities juan in this valley as well as in the wyoming Vy oming fields to the northeast the question of an oil fuel motor or engine is at once interesting and attractive the accompanying halftone half tone illustration is intended to show a sectional view of the Arne american rican type of diesel engine the invention of mr rudolph diesel of germany an eini eminent nent scientist in engineering in that country this engine promises to bring about a great change in the matter of power gener aaion in sections remote from water or fuel as it is already attracting attention and beg ing placed alongside of other engines in all states and the southern pacific railroad company has placed one one in its shops at tucson arizona with such pronounced success that another one is being installed in tho the ogden shops of the same company the fuel is absolutely the cheapest crude oil which is safe and not gasoline naptha or dangerous in flammables there is no ex as in all ether gas or oil engines but steady eady combustion at a much lower temperature pera ture and without essential increase in Dres pressure sure the manufacturers claim much greater economy than that of the best triple expansion engine with fuel consumption almost in direct proportion to the horsepower horse power delivered or to be most exact double the economy of the most perfect triple ex expansion mansion steam engine and fifty per cent greater than other gas or oil engines the structural features of this engine is very similar to many others the thermal efficiency is as high as 38 per cent there is no boiler or other mechanism more than may be seen in the simple sectional view herein shown with accompanying pipes and fuel tank necessary george F busch of the fred J kiesel co ogden is western AWN 77 t KP SECTIONAL VIEW OF av DIESEL ENGINE i representative who will furnish catl upon application the engine has been en by such leading power and machinery papers as the journal of american society of engineers progressive age journal of E engineering ngi societies journal of the franklin in institute sibley journal mining and scientific press electrical world electrical engineer street railway journal and many others power editorially discussing the working merits of the diesel engine recently says As seen in the sectional view nea nearly hor horizontal irly arms pivoted at one end to the housing carry rollers on the ends which are in contact with the cams they are held down by springs and the vertical valve rods rodd rest upon and are moved by them the movement of the admission valve is very slight the compressed air from auxiliary compressor comes through the vertical pipe into the same space but behind the oil which Is delivered from the oil pump through a pipe at the side not shown surrounding the valve spindle is a series of brass washers whose shape can bewell be well seen and which are perforated parallel to the spindle by numerous small holes the oil occupies the cavities between the washers and by capillary action finds its way into the perforations and between the washers the opening of the fuel valve allows the compressed air to drive out through the perforated washers the oil in the form of a fine spray it is driven into the cylinder and ignited by the extremely high temperature of the air compressed by the up stroke of oe the piston any grade of crude or fuel oil may be used the air which supports combustion is drawn into the ey cylinder finder through the automatic mushroom valve shown and compressed by the up stroke of the piston to between and pounds per square inch the resulting temperature approaches 1000 degrees fahr and this is much more than sufficient to ignite ahe the oil as soon as it is injected at the commencement of the down stroke the fuel valve opens remaining open for about a tenth of the stroke and fuel is admitted and burned during the whole hole w or part of this period according to the action of the governor after the fuel supply is stopped the resulting gases of combustion work expansively during the rest of the stroke |
