Excerpt from The Gas and Oil Engine In this edition special attention has been paid to the oil engine, in view of its rapid rate of present development and the probability of its very extensive use for many new purposes, such as motor cars. Many engineers are now paying attention to the oil engine, to whom the subject is unfamiliar and in the hope of proving useful to such new men on the work, the author has gone caref'ully into the discussion of the chemical nature of petroleum and the different methods of vaporising heavy oils.
