Which of the following is not a classification of IC engines?
Two-stroke engine
Four-stroke engine
Rotary engine
Electrical motor
Which of the following is a component of a basic engine construction?
Electrical system
Power steering system
Braking system
Ignition system
What are the cycles of engine?
Air cycle, fuel cycle, power cycle
Intake cycle, compression cycle, power cycle, exhaust cycle
Fuel cycle, compression cycle, ignition cycle, exhaust cycle
Air cycle, compression cycle, ignition cycle, exhaust cycle
Which type of engine has a higher power-to-weight ratio?
Two-stroke engine
Four-stroke engine
Both have the same power-to-weight ratio
It depends on the specific engine design
What is the difference between a petrol engine and a diesel engine?
Petrol engines use spark ignition, while diesel engines use compression ignition
Petrol engines use compression ignition, while diesel engines use spark ignition
Petrol engines have more cylinders than diesel engines
Petrol engines are larger than diesel engines
What is the purpose of the intake system in an engine?
To mix air and fuel
To ignite the fuel-air mixture
To direct exhaust gases away from the engine
To provide lubrication to the engine parts
Which engine system is responsible for regulating the fuel injection in a diesel engine?
Carburetor system
Fuel injection system
Ignition system
Exhaust system
What is the role of the exhaust system in an engine?
To provide oxygen to the engine
To regulate the fuel injection
To cool the engine
To direct exhaust gases away from the engine and reduce emissions
What is the purpose of the lubrication system in an engine?
To mix air and fuel
To provide power to the engine
To cool the engine
To reduce friction between moving engine parts
Which of the following engine cycles is used in most modern cars?
Two-stroke cycle
Four-stroke cycle
Six-stroke cycle
Eight-stroke cycle
What is the function of the radiator in a liquid-cooled engine?
To provide a spark to ignite the fuel-air mixture
To regulate the engine oil pressure
To cool the engine coolant
To filter impurities from the fuel
What is the role of the catalytic converter in the exhaust system?
To reduce emissions of harmful pollutants
To increase the power output of the engine
To direct exhaust gases away from the engine
To filter impurities from the fuel
What is the difference between a naturally aspirated engine and a turbocharged engine?
Naturally aspirated engines are less fuel-efficient than turbocharged engines
Turbocharged engines have a larger displacement than naturally aspirated engines
Naturally aspirated engines rely on atmospheric pressure for air intake, while turbocharged engines use a turbocharger to force air into the engine
Turbocharged engines are slower than naturally aspirated engines
What is the difference between a carburetor and fuel injection?
Carburetors mix air and fuel outside of the engine, while fuel injection mixes air and fuel inside the engine
Carburetors mix air and fuel inside the engine, while fuel injection mixes air and fuel outside of the engine
Carburetors are more fuel-efficient than fuel injection
Fuel injection is only used in diesel engines
