A practical, field-ready guide to measuring engine power and boiler efficiency.
This book compiles proven indicator methods, braking approaches, and diagram analysis to help engineers and technicians understand and improve engine performance.
It surveys the range of indicators used in early and modern testing, explains how to mount and operate them, and shows how to read diagrams for real-world results. The volume also covers testing gas and oil engines, calculating indicated and brake horsepower, and evaluating different braking systems and automatic brakes.
- Clear explanations of indicators, from basic to advanced, and how they translate piston movement into usable data.
- Practical methods for measuring indicated and brake horsepower, with attention to setup and calculations.
- Descriptions of various braking devices and automatic brakes, including how they affect test results.
- Guidance on analyzing diagrams, selecting appropriate springs, and interpreting test outcomes.
Ideal for readers working with steam and internal-combustion engines who want reliable testing methods and actionable benchmarks.
