An Important Book on Engines: Mr. Pye's Book Gives Adequate Treatment to the Physico‐Chemical Side of Engine Design

Mr. Pye's book sets a high standard for those who are to follow him in this series. It consists of seven chapters and some 250 pages admirably printed on excellent paper. It has an adequate list of references, well arranged tables of relevant physical constants, and a good index. It abounds in numerical illustrations, but has no “examples.” It contains no enigmatic “working drawings.” It sticks to the point, which is to present a logical account of the principles which underlie the design and operation of the internal combustion engine.
