Excerpt from Motor Vehicle Engineering Engines: Their Design and Construction (for Automobiles, Trucks, and Tractors) The necessity of revising certain portions of this book having arisen, the author took advantage of the opportunity to make a more thorough revision of the entire work than was originally contemplated. As a result many chapters have been entirely rewritten, numerous formulae changed to show their derivation from standard practice, and practical data added or brought up to date.
