Lyle Cummins continues his series on the internal combustion engine's
heritage. Internal Fire, his introductory volume, is in its second
edition. The author is uniquely qualified to tell the diesel story.
Raised in the family of America's automotive diesel pioneer, his career
as a mechanical engineer includes the design, development and marketing
of diesel engine retarders and fuel systems for which he was granted
five U .S. patents. He has received several notable awards for his
writings on I-C engine history. Cummins has devoted over two decades
exhaustively researching his subject in corporate and museum archives
throughout Europe and the United States to provide this definitive
history of the diesel.
