Intro to Fuel Circuit Quiz

What are the two main types of fuel circuits?

• Carburetor fuel circuit and fuel injection circuit

• Primary fuel circuit and secondary fuel circuit

• Gasoline fuel circuit and diesel fuel circuit

• Electric fuel circuit and hydraulic fuel circuit

Explain the working principle of a carburetor fuel circuit.

• The carburetor fuel circuit mixes water and fuel for the engine

• The carburetor fuel circuit has no impact on the engine's performance

• The carburetor fuel circuit only supplies air to the engine

• The carburetor fuel circuit mixes air and fuel to create a combustible mixture for the engine.

Describe the function of a fuel injection system in a vehicle.

• It controls the temperature of the engine

• It delivers the right amount of fuel to the engine's combustion chambers at the right time.

• It regulates the air flow in the vehicle

• It monitors the tire pressure

Differentiate between a single-point fuel injection system and a multi-point fuel injection system.

• The single-point fuel injection system uses one injector to supply fuel to all cylinders, while the multi-point fuel injection system uses multiple injectors, one for each cylinder.

• The single-point fuel injection system uses multiple injectors, one for each cylinder, while the multi-point fuel injection system uses one injector to supply fuel to all cylinders.

• The single-point fuel injection system is more efficient than the multi-point fuel injection system.

• Both single-point and multi-point fuel injection systems use the same number of injectors.

What are the advantages of a carburetor fuel circuit over a fuel injection system?

• Noisy operation, higher fuel consumption, and increased emissions

• Less efficient, more expensive, and harder to repair

• Simpler design, lower cost, and easier maintenance

• More complex design, higher cost, and difficult maintenance

What are the disadvantages of a carburetor fuel circuit compared to a fuel injection system?

• Less efficient and poorer fuel economy

• Simpler design and easier maintenance

• Higher performance and smoother operation

• More efficient and better fuel economy

Explain the concept of a continuous fuel circuit.

• A continuous fuel circuit is a system in which the fuel is only circulated when the engine is running.

• A continuous fuel circuit is a system in which the fuel is only circulated when the fuel tank is full.

• A continuous fuel circuit is a system in which the fuel is constantly circulated from the fuel tank to the engine and back to the tank.

• A continuous fuel circuit is a system in which the fuel is stored in the engine until it is needed.

Discuss the characteristics of a pulsating fuel circuit.

• Intermittent fuel flow, rapid pressure changes, and pulsating fuel delivery to the engine

• Intermittent fuel flow, slow pressure changes, and consistent fuel delivery to the engine

• No fuel flow, constant pressure, and no fuel delivery to the engine

• Steady fuel flow, slow pressure changes, and consistent fuel delivery to the engine

How does a fuel pump operate in a fuel circuit?

• It filters the air before it reaches the engine

• It draws fuel from the tank and delivers it to the engine

• It signals the driver when the fuel level is low

• It controls the temperature of the fuel in the tank

What are the common issues associated with fuel circuits in vehicles?

• Dead battery, faulty air conditioning, and cracked windshield

• Leaks, clogs, and faulty fuel pumps

• Flat tires, engine overheating, and broken windshield wipers

• Broken taillights, squeaky brakes, and dirty windows
