Excerpt from Diesel Engine in Practice
The interest which has been aroused in this country over the Diesel engine in the past few years is remarkable, but not nearly so much so as the engine itself. Until four years ago there were but few builders of the Diesel engine in America. At the present time there are twenty or more manufacturers building different types of Diesel engines, several of them adopting foreign designs. Between four hundred and five hundred plants in the United States are now being operated with engines of the Diesel type, ranging from one to as high as eighteen engines in a plant.
It has been the duty of one of the authors to visit most of these plants in the capacity of an instructor, and in so doing he became acquainted with the men who are operating and also the knowledge they had of their work.
It is safe to state that not ten per cent of the operators of Diesel engines know one-quarter as much about their engines as the average steam engineer knows about his engine. Naturally there is a reason for this - a steam engineer, before he receives his license, is generally compelled to fire a boiler for two or three years and sometimes longer. Then he receives a fireman's license, and in two or three years more of firing the boiler, if he can pass a certain examination, he is eligible to a third class steam engineer's license. They do all this work gladly to learn the business.
