What is the fundamental principle behind an internal combustion engine (ICE)?
Harnessing electrical power for propulsion
Utilizing air pressure for motion
Converting chemical energy into mechanical energy
Converting heat energy into kinetic energy
What is the purpose of a cylinder in an internal combustion engine?
To burn fuel explosively
To convert chemical energy to mechanical energy
To transmit power from piston to crankshaft
To enclose the chamber where fuel is burnt
What is the air/fuel mixture in an internal combustion engine?
A mixture of fuel and air in a specific ratio
The movement of the intake valve
The process of compression
The movement of the exhaust valve
How is power transmitted to the wheels in an internal combustion engine?
Connecting rod to crankshaft
Crankshaft to drive shaft
Drive shaft to wheels
All of the above
What is a stroke in an internal combustion engine?
Complete half crankshaft rotation
Complete piston movement up and down
The process of combustion
The movement of the intake valve
When comparing 4-stroke and 2-stroke engines, which statement is correct?
4-stroke engines are less fuel-efficient than 2-stroke engines.
2-stroke engines have a more complex design with additional moving parts.
4-stroke engines have intake and exhaust strokes.
2-stroke engines are generally heavier than 4-stroke engines.
What is the stoichiometric air/fuel mixture ratio for an internal combustion engine?
14.7:1
Less than 14.7
More than 14.7
Depends on the fuel type
When comparing combustion spark and compression ignition engines, which statement is correct?
Combustion spark engines rely on compressing air and fuel mixture before ignition.
Compression ignition engines are commonly used in gasoline-powered vehicles.
Combustion spark engines operate without the need for spark plugs.
Compression ignition engines require a spark to initiate combustion.
In the context of comparing combustion spark and compression ignition engines, which of the following statements is accurate?
Combustion spark engines are primarily used in diesel vehicles.
Compression ignition engines use spark plugs to initiate combustion.
Combustion spark engines rely on the heat generated by high compression to ignite the air-fuel mixture.
Compression ignition engines are also known as diesel engines.
