Understanding Fuel Injectors in Cars

What is the primary function of a fuel injector in an automotive engine?

• To increase the engine's horsepower

• To deliver fuel into the combustion chamber

• To cool the engine

• To lubricate engine parts

Which of the following is NOT a type of fuel injector?

• Throttle body injector

• Direct injector

• Carburetor injector

• Port injector

How does a fuel injector operate in a modern engine?

• It uses a mechanical pump to spray fuel

• It uses an electronic signal to open and close a valve

• It relies on gravity to feed fuel into the engine

• It uses a vacuum to draw fuel into the combustion chamber

What is a common problem associated with fuel injectors?

• Overheating

• Clogging

• Excessive noise

• Oil leakage

Which method is commonly used for cleaning fuel injectors?

• Sandblasting

• Ultrasonic cleaning

• High-pressure water jet

• Chemical etching

What is one technique used to test the functionality of a fuel injector?

• Visual inspection

• Compression test

• Flow rate test

• Spark plug test

What impact does a malfunctioning fuel injector have on engine performance?

• Increased fuel efficiency

• Reduced emissions

• Engine misfires

• Improved acceleration

Which type of fuel injector is known for delivering fuel directly into the combustion chamber?

• Throttle body injector

• Port injector

What is the role of the electronic control unit (ECU) in managing fuel injectors?

• To manually adjust the fuel flow

• To provide real-time data to the driver

• To control the timing and amount of fuel injected

• To clean the fuel injectors automatically

Which component works closely with fuel injectors to ensure optimal air-fuel mixture?

• Throttle body

• Exhaust manifold

• Radiator

• Oil filter
