9. Which of the following is not a characteristic of an external combustion engine?
O A. External pistons are used.
O B. Fuel is sent directly to the engine.
O C. Steam is sent to the engine to produce power.
O D. Boiler burns fuel to produce steam.

Answer 1

External combustion engines use external pistons and steam sent to the engine for power, but do not have fuel sent directly to the engine.

Step-by-step explanation:

The correct answer is B. Fuel is sent directly to the engine. This is not a characteristic of an external combustion engine. In external combustion engines, such as steam engines, fuel is burned in a separate chamber, typically a boiler, to produce steam. The steam is then sent to the engine to produce power. External pistons are used in external combustion engines, and steam is sent to the engine to produce power.
