🔍 Key Concepts

• indicated horsepower (ihp) vs brake horsepower (bhp) — where and how each is measured • what mechanical losses (friction, pumps, auxiliaries) do inside an engine • difference between thermal efficiency and other efficiency terms used with diesel engines

💭 Think About

• Ask yourself: which efficiency term compares the power developed inside the cylinders to the power actually available at the crankshaft? • Think about where indicated horsepower is measured (inside the cylinder from pressure) and where brake horsepower is measured (at the output shaft). What is lost between those two points? • Which of the listed efficiencies is specifically about engine friction and moving parts, not fuel heat input or air intake volume?

✅ Before You Answer

• Be clear on the definition of indicated horsepower (ihp) — power calculated from cylinder pressure diagrams. • Be clear on the definition of brake horsepower (bhp) — power measured at the output shaft on a dynamometer or propeller load. • Match the ratio "bhp / ihp" to the term that describes how well the engine’s moving parts transmit power, not how well it turns fuel heat into work.
