Pre-test and Post Test: Heat Engine

It refers to the machine that converts energy from a fuel to some mechanical energy, creating a motion in the process.

• Engine

• Heat Engine     

• Machinery

• Machine

The following statements refers to how heat engine perform work EXCEPT:

• heat is taken by the engine from the heat source.

• most of the heat taken goes into the low temperature reservoir.

• the remaining energy obtained is converted as useful mechanical work.

• None of these

This refers to any internal combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder.

• Combustion Engine

• Diesel Engine

• Gasoline Engine

• Heat Engine

This is any of a class of internal-combustion engines that generate power by burning a volatile liquid fuel.

• Combustion Engine

• Diesel Engine

• Gasoline Engine

• Heat Engine

Which of the following statements makes the diesel engine different from gasoline engine?

• the way the fuel is burned.

• the way the fuel goes in the engine.

• the way the fuel is ignited.

• the way the fuel is compressed.

During this stroke cycle, the piston moves up, compressing the fuel mixture.

• Intake stroke

• Compression stroke

• Power stroke

• Exhaust stroke

During this stroke cycle, the combusted gases are pushed out of the open exhaust bulb through an upward motion on the piston.

• Intake stroke

• Compression stroke

• Power stroke

• Exhaust stroke
