External and Internal Combustion Engines

Where does fuel combustion occur in an External Combustion Engine (EC Engine)?

• Inside the engine cylinder

• Outside the engine

• In the fuel tank

• In the exhaust system

What type of fuel can External Combustion Engines use?

• Only liquid fuels

• Only gaseous fuels

• Solid, liquid, or gas

• Only solid fuels

Where does fuel combustion occur in an Internal Combustion Engine (IC Engine)?

• Outside the engine

• Inside the engine cylinder

• In the fuel tank

• In the exhaust system

What is an advantage of Internal Combustion Engines?

• More compact and lightweight

• Slower response time

• Lower efficiency

• Bulky and heavy

What is a disadvantage of Internal Combustion Engines?

• Limited to liquid or gaseous fuels

• Can use solid fuels

• Runs smoothly with fewer vibrations

• Lower efficiency for transportation

Which engine type is more efficient for transportation applications?

• External Combustion Engine

• Internal Combustion Engine

• Both are equally efficient

• Neither is efficient

What is a key feature of External Combustion Engines regarding fuel types?

• Mostly liquid or gas

• Only gaseous fuels

• Solid, liquid, or gas

• Only liquid fuels

Which engine type has a faster response time?

• External Combustion Engine

• Internal Combustion Engine

• Both have the same response time

• Neither has a fast response time

Which of the following is an example of an External Combustion Engine?

• Gasoline engine

• Diesel engine

• Steam engine

• Jet engine

What is a disadvantage of External Combustion Engines compared to modern IC engines?

• Higher efficiency

• Slower response time for power output changes

• More compact

• Less noise
