The Petrol Engine
 A Text-book dealing with the Principles of Design and Construction, with a Special Chapter on the Two-stroke Engine

by Francis John Kean

"The Petrol Engine" by Francis John Kean is a scientific publication written in the early 20th century. This text serves as a textbook on the principles of design and construction of petrol engines, with a specific focus on the two-stroke engine. The book appears to aim at understanding the functioning of petrol engines, discussing concepts such as explosive mixtures, suction, and the Otto cycle, which governs engine operation. The opening of this work outlines its goal to educate readers on the basic principles rather than merely detailing existing engine types. Kean emphasizes the importance of understanding components like carburetors and ignitions, providing foundational knowledge necessary for engineers and mechanics. It details essential processes such as the generation of explosive mixtures and the mechanics of engine operation, further setting the stage for a detailed exploration of the structure and function of various engine parts. Overall, it targets an audience interested in motor engineering and seeks to provide them with a solid grounding in essential principles.
