Limited printing. The book is printed in color on semi-gloss paper for enhanced picture reproduction. Book size is 8½ x 11 inches with dust jacket. Please see our Publications page for ordering information. About the Author: Wayne Grenning has been interested in engines for decades and has restored many early engines, flame ignition and otherwise, as well as creating operating scale and full size models of a variety of early flame ignition and non-compressing engines. A fixture at Coolspring during the shows, Wayne has gathered all of his knowledge together into this book as a technical and historical reference to this important chapter in internal combustion engine history. The Coolspring Power Museum CollectionInternal combustion engines revolutionized the world around the turn of the 20th century in much the same way that steam engines did a century before. One has only to imagine a coal-fired, steam-powered, airplane to realize how important internal combustion was to the industrialized world. While the early stationary gas engines were more expensive than the equivalent steam engines, they did not require a boiler and were cheaper to operate. The Coolspring Power Museum collection documents the early history of the internal combustion revolution. Almost all of the critical components of today's engines have their origins in the period represented by the collection (as well as hundreds of innovations that are no longer used). Some of the engines represent real engineering progress. Others are more the product of inventive minds avoiding previous patents. All tell a story. There are few duplications in the collection and only a couple of manufacturers are represented by more than one or two examples. The Coolspring Power Museum contains the largest collection of historically significant, early stationary gas engines in the country, if the not the world. With the exception of a few items in the collection that were driven by the engines, such as compressors, pumps, and generators, and a few steam and hot air engines shown for comparison purposes, the collection contains only stationary internal combustion engines. The collection consists mainly of stationary gas engines used in industrial applications. There are only a few marine, automotive, and farm engines in the collection and the museum does not plan to expand its focus into those areas. Most of the museum's acquisitioning efforts (those that involve substantial expenditure of funds and volunteer time) have been focused on collecting important large stationary engines that most likely would be scrapped if the museum did not acquire them. The museum's passive collecting efforts are directed at filling technological gaps in the collection by accepting donations from private collectors and occasionally other museums. The museum also maintains a substantial library and archive related to the objects in the collection and to the internal combustion engine in general. The Collection consists primarily of engines built in America because that is what was available to the museum. However, the technology on which they are based comes from both sides of the Atlantic. The American Society of Mechanical Engineers recognizes Coolspring Power Museum as a Mechanical Engineering Heritage Collection. Please see our History page for more information. Cam-Ron Video Productions prepared an installment of their Kaleidoscope The Series program showcasing Coolspring Power Museum. This video gives a brief history of the museum, features a number of museum volunteers and visitors, and overviews a few of the museum's exhibits.

The museum is a 501(c)(3) nonprofit organization and contributions are TAX DEDUCTIBLE to the extent allowed by law. The Coolspring Power Museum volunteers are planning Diesel Centrale CPM, a new exhibit to feature our MAN/Augsburg DM-12 air-blast injection diesel engine, which was built in 1903 and is shown here. Diesel Centrale CPM will also feature a 12 hp Graz diesel engine, built in 1904, and a 12 hp Benz, built in 1918. We need significant financial support to complete this project. Our goal is to bring this historic engine back to running condition for the education and enjoyment of our visitors. Visit our Diesel Centrale CPM page for more information and to follow our progress. Please consider making a financial contribution to support the MAN project. We plan to begin permanently mounting the engines in the building in the spring of 2023 and to have them operational for our June 2024 exposition. More than $240,000 has been raised for the project and the Coolspring Power Museum has loaned an additional $50,000 from operating funds. However, with inflation and delays caused by COVID-19, project costs have grown significantly beyond our available funds and an additional $135,000 (including the loan repayment) is needed to complete the project. In the near term, we need to raise at least $35,000 of that amount by March 2023 to commit to orders for the completion of the building exterior (doors, windows, brick, etc.). Donations have been requested from several corporate entities, but the bulk of our funding comes from individuals. Any amount will be helpful and greatly appreciated! Several more 4- and 5-figure donations are needed to reach our goal. Donors will be recognized at the following giving levels on a plaque inside the finished building. Diesel Centrale Level ($25,000) Donations in excess of $25,000 will have their own special recognition plaque. Donor recognition will be based on cumulative (aggregate) donations to the project, so, for example, if you donated $1,000 previously and now donate another $1,500, you would advance from the Flywheel Level to the Air Blast Level. Please send donations to: Coolspring Power Museum The Coolspring Power Museum would be honored to add your name as a significant donor. If you have any questions relating to the project or donations, please contact Norm Shade, project coordinator (T: 713-206-9651 or E-mail: nshade@aciservicesinc.com).

This book is a scholarly work describing
flame ignition as applied to reciprocating engines, from early
experiments to later successes such as the Deutz and Crossley versions
of the four stroke cycle perfected by Otto in 1876. Wayne discusses
problems encountered by the early entrants into the gas engine industry,
highlighting solutions discovered by the various players. He also
goes into more arcane subjects like the constant pressure cycle
introduced by Brayton that survives today in the gas turbine engine, to
a look at toy non-compression engines produced during the same early
days as their full size brethren. In eight chapters, Wayne shows
details of engines built by Clerk, Sombart, Forest and others, gives
technical details on the construction and operating features unique to
flame ignition engines, and highlights the struggles other manufacturers
endured to avoid infringing the Otto patents. The section on the
four-stroke-cycle engines is by itself over 300 pages long, covering 30
different companies. It has 67 pages describing the activities of
Crossley Brothers in Manchester, England and another 53 pages dedicated
to Gasmotoren Fabrik Deutz from Cologne, Germany.
