"A Diesel engine is an amazing assortment of bolts, nuts, valves, heaters, coolers, expanders, contractors, and other gadgets too numerous to mention here. All of these are screwed and welded together to form a single unit. This resulting unit is expected to start out with below the usual grade of fuel oil and change it into BTU - then the BTU into MEP - the MEP into RPM - the RPM into BHP - the BHP into KWH. Then the electrical gear takes over and makes a BHP out of KWH and RPM out of BHP, and then, if everything is in working order, you finally get MPH. All of this takes place in a fraction of a second in the confines of an all-too-small engine room. This gives you a rough idea of the confusion characteristic to all Diesel Freight Units..."
"A Diesel engine has several important parts that should be mentioned, among them is the cylinder. This is a long round hole filled with air that is covered on one end with a cover full of holes containing valves that admit fuel, air and sometimes water and carelessly placed tools. These valves open and close according to a predetermined sequence of events. The other end is plugged with a movable plug called a piston. This is free to move up and down within certain limits and would come out altogether if it were not for the connecting rod. This connecting rod is important, too, as it is what changes MEP into RPM, and without it we would be stuck with the MEP, which no one knows how to use up to now. This whole assembly is held in place by crab studs and nuts to prevent it from joining the bird gang. Each cylinder has four crabs, so we might be more considerate of the noise that the engine makes, considering the noise that you would make if you had the same number of crabs. "
