| Show THE DIESEL CRUDE OIL ENGINE the time is opportune for discussing the merits of an engine which requires neither fuel or water to generate power and which should interest those who are operating under conditions which make the use of fuel and water prohibitive the machine mentioned consists of a belt driven air compressor which generates about sixty five atmospheres the more important part of the engine consisting of a frame of the vertical box type main center crank encased in oil trunk piston and four valves cam driven with their connections one valve is for mechanically admitting free air which forms part of the charge tor for power one for ad fuel oi oil lone one for its exhaust and one for starting the engine the starting of the engine is very easy being semi auto matic the piston is placed on the top cen ter and air of sixty to sixty five atmos cheres generated by the compressor is ig drawn from reserve tanks which forces the piston down and the momentum of the fly wheels carries the piston up compressing free air to about pounds per square inch at this point the fuel oil is injected into the cylinder and ignited by the high compression at the lower end the exhaust ta takes kes place the engine is a four cycle using oil each alternate stroke runs with surprising regularity and makes very little noise but one charge of reserve air is used in starting and the fuel oil is automatically turned in by a strange coincidence the diesel engine is manufactured in the george H corliss old works at providence R I 1 who once made the unique but profitable proposition to the new england textile manufacturers to substitute corliss engines gratis if they would pay him the difference in the price of fuel consumed and the diesel engine makers may now safely emulate his example and supplant the corliss with the diesel engines A seventy five horsepower horse power diesel engine is driving all the machinery in the southern pacific shops at ogden and uses twenty gallons of crude fuel oil and one gallon of lubricating oil the former costing and the latter per gallon in twelve hours and a one inch pipe will supply all the water necessary to keep the cylinder cool the engine here is running twenty three out of the twenty four hours every day in the month |
