Carb vs Injection

What is the primary function of a carburettor in an internal combustion engine?

• To mix air and fuel in the correct ratio for combustion

• To inject fuel directly into the combustion chamber

• To cool the engine

• To filter the air entering the engine

Which of the following is an advantage of fuel injection over carburettors?

• Simpler design

• Better fuel efficiency

• Lower cost

• Easier maintenance

How does fuel injection improve engine performance compared to carburettors?

• By providing a more precise air-fuel mixture

• By reducing the engine size

• By increasing the engine temperature

• By simplifying the engine design

According to Bernoulli's Principle, what happens to the pressure of a fluid as its velocity increases?

• The pressure increases

• The pressure decreases

• The pressure remains constant

• The pressure fluctuates

Which component in a carburettor is responsible for controlling the amount of fuel entering the engine?

• Throttle valve

• Float chamber

• Jet

• Choke

What is one of the main disadvantages of carburettors compared to fuel injection systems?

• Higher cost

• Less precise fuel delivery

• More complex design

• Higher maintenance requirements

In a fuel injection system, where is the fuel typically injected?

• Into the air intake manifold

• Directly into the combustion chamber

• Into the exhaust manifold

• Into the carburettor

Which principle explains the operation of a carburettor?

• Newton's Third Law

• Bernoulli's Principle

• Pascal's Law

• Archimedes' Principle

What is a common benefit of using fuel injection in modern vehicles?

• Increased engine noise

• Improved fuel economy

• Higher emissions

• Increased engine weight

Which of the following best describes the difference between carburettors and fuel injection systems?

• Carburettors mix air and fuel before entering the combustion chamber, while fuel injection systems inject fuel directly into the combustion chamber.

• Carburettors are used in diesel engines, while fuel injection systems are used in petrol engines.

• Carburettors are more expensive than fuel injection systems.

• Fuel injection systems are less efficient than carburettors.
