Chapter 3 Fuel and Exhaust System (Part 2)

Which of the following is a harmful exhaust emission?

• Carbon dioxide (CO2)

• Nitrogen (N2)

• Carbon monoxide (CO)

• Oxygen (O2)

The most common harmful exhaust emissions include carbon monoxide (CO), nitrogen oxides (NOx), and __________.

• oxygen (O2)

• carbon dioxide (CO2)

• sulfur dioxide (SO2)

• Hydrocarbon (HC)

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

• To regulate the backpressure in the exhaust system

• To direct the flow of fuel to each cylinder

• To collect and channel the exhaust gases from each cylinder

• To deliver air to the engine's combustion chamber

What is a carburetor?

• A device used to regulate the backpressure in the exhaust system

• A device used to filter harmful particulate matter from the exhaust gas

• A device used to mix air and fuel for combustion in the engine

• A device used to collect and channel the exhaust gases from each cylinder

What is the function of the float chamber in a carburetor?

• To regulate the flow of fuel to the engine

• To filter out harmful particulate matter from the fuel

• To store excess fuel for later use

• To maintain a constant level of fuel in the carburetor's bowl

What is a fuel injection system?

• A device used to mix air and fuel for combustion in the engine

• A device used to collect and channel the exhaust gases from each cylinder

• A device used to regulate the backpressure in the exhaust system

• A system used to deliver fuel to the engine in a precise and controlled manner

What are the two main types of fuel injection systems?

• Sequential and simultaneous

• Direct and indirect

• Passive and active

• Mechanical and electronic

What is a fuel injection sensor?

• A device used to regulate the flow of fuel to the engine

• A device used to filter harmful particulate matter from the fuel

• A device used to measure the amount of fuel injected into the engine

• A device used to collect and channel the exhaust gases from each cylinder

Which of the following is a type of fuel injection sensor?

• oxygen sensor

• air temperature sensor

• crankshaft position sensor

• all of the above

What is direct fuel injection?

• A fuel injection system that injects fuel directly into the engine's combustion chamber

• A fuel injection system that uses an intermediate chamber to inject fuel into the engine

• A fuel injection system that delivers fuel to the engine through a carburetor

• A fuel injection system that delivers fuel to the engine through a mechanical pump
