Understanding Vehicle Systems

What are the main components of a fuel system?

• Spark plugs, ignition coil, radiator, brake system

• Fuel gauge, fuel cap, air filter, exhaust system

• Fuel tank, fuel pump, fuel filter, fuel injectors (or carburetor), fuel lines.

• Oil reservoir, coolant system, battery, transmission

Explain the primary function of the fuel pump in a vehicle.

• To ignite the fuel in the combustion chamber.

• To transport fuel from the tank to the engine.

• To cool the engine components.

• To filter impurities from the fuel.

Describe how the radiator contributes to the cooling system.

• The radiator heats the engine coolant to improve performance.

• The radiator cools the engine coolant by maintaining optimal engine temperature.

• The radiator filters impurities from the coolant before circulation.

• The radiator increases the pressure in the cooling system to boost efficiency.

What role does coolant play in the cooling system?

• Coolant increases engine temperature by storing heat.

• Coolant regulates engine temperature by absorbing and dissipating heat.

• Coolant filters impurities from the engine oil.

• Coolant is used to lubricate engine parts.

Identify the key components of a lubrication system.

• Fuel injection system parts

• Lubricant additives and emulsifiers

• Cooling system components

• Lubricant reservoir, pump, filters, distribution lines, and lubrication points.

Why is oil viscosity important in a lubrication system?

• Oil viscosity has no impact on engine temperature.

• It reduces friction and wear in the system.

• Higher viscosity oils are always better for lubrication.

• Oil viscosity affects the color of the oil.

List the main parts of a brake system in a vehicle.

• transmission system

• engine components

• brake pedal, master cylinder, brake lines, brake calipers, brake pads, brake rotors

• fuel injectors

How do disc brakes differ from drum brakes?

• Disc brakes are heavier than drum brakes.

• Disc brakes offer better performance and heat dissipation compared to drum brakes.

• Disc brakes are more prone to rust than drum brakes.

• Drum brakes provide better heat dissipation than disc brakes.

What factors affect the effectiveness of a brake system?

• Brake system color

• Brake fluid quality

• Engine type

• Fuel quality

Explain the importance of brake fluid in the brake system.

• Brake fluid is crucial for transmitting force in the brake system

• Brake fluid helps in cooling the engine during operation.

• Brake fluid is used to lubricate the brake pads.

• Brake fluid is primarily for cleaning the brake system.
