Chapter 3 Fuel and Exhaust Systems (Part 1)

Which of the following is responsible for delivering fuel to the engine?

• Exhaust system

• Induction system

• Fuel system

• Lubrication system

What is the function of the fuel pump in the fuel system?

• increase the fuel pressure

• To filter the fuel before it enters the engine

• To atomize the fuel before it enters the combustion chamber

• To pump fuel from the fuel tank to the engine

What is the function of a fuel filter?

• To mix fuel and air before entering the combustion chamber

• To remove impurities and debris from the fuel

• To regulate the fuel pressure

• To store excess fuel for later use

What is the benefit of proper maintenance and tuning of the fuel system?

• Increased engine performance and fuel efficiency

• Decreased engine performance and fuel efficiency

• Increased engine noise and emissions

• Decreased engine noise and emissions

Which of the following is a sign of a malfunctioning fuel system?

• Engine starting easily and running smoothly

• Decreased fuel efficiency

• Decreased engine power

• Increased engine performance

Which of the following is the primary function of the exhaust system in an automotive engine?

• To reduce engine noise

• To improve engine performance

• To increase fuel efficiency

• To remove harmful exhaust gases

What is the purpose of an exhaust manifold in an automotive engine?

• To reduce the noise produced by the engine

• To direct the flow of exhaust gases from each cylinder to the exhaust system

• To filter out harmful particulate matter from the exhaust gas

• To regulate the backpressure in the exhaust system

Which of the following exhaust system components is responsible for reducing harmful emissions by converting them into less harmful compounds?

• Muffler

• Exhaust manifold

• Exhaust pipe

• Catalytic converter

Which of the following exhaust system components is responsible for reducing engine noise?

• Muffler

• Exhaust manifold

• Exhaust pipe

• Catalytic converter

How can excessive backpressure in an exhaust system affect engine performance?

• It can cause increased fuel efficiency

• It can reduce engine power and performance

• It can improve the efficiency of the catalytic converter

• It can increase engine noise and vibration
