Brève description / annotation

"The Gasoline Motor" by Harold Whiting Slauson provides a comprehensive examination of the mechanics and operation of gasoline engines, focusing on the intricacies of motor types, valve systems, and bearings. The text begins by distinguishing between two-cycle and four-cycle engines, explaining the sequence of events necessary for engine operation, such as the intake, compression, ignition, and exhaust processes. Slauson elaborates on the differences between these engine types, highlighting the efficiency and simplicity of two-cycle engines compared to the more complex four-cycle engines, which are more common in automobiles due to their higher fuel efficiency and power output. The discussion then shifts to the role of valves in engine operation, emphasizing the importance of timing and the various types of valves, including poppet and sleeve valves. Slauson explains the mechanics of valve operation, the significance of proper timing, and the methods for adjusting and maintaining valve systems to ensure smooth engine operation. In the section on bearings, Slauson delves into the critical role bearings play in supporting the engine's moving parts, particularly the crankshaft and connecting rods. He discusses the materials used for bearings, such as babbitt metals, and the importance of proper lubrication to prevent wear and overheating. The text also covers the process of adjusting and renewing bearings to maintain engine efficiency and prevent damage. Overall, Slauson's work serves as a detailed guide for understanding the fundamental components and operations of gasoline motors, providing valuable insights for engineers, mechanics, and automotive enthusiasts.
