Fuel Injector Components and Functions

The video tutorial provides an overview of fuel injectors, focusing on their location, installation options, and the design of electromagnetic fuel injectors. It explains the components and operation of the electromagnetic coil, detailing how it controls the valve to spray fuel. The tutorial also covers the various parts of the injector, such as the valve seat and spray disc, and discusses different types of valves used in injectors.

Where are fuel injectors typically located within a vehicle?

• In the transmission system

• In the cooling system

• In the fuel injection system

• In the exhaust system

What is the primary function of a fuel injector?

• To cool the engine

• To spray fuel into the intake manifold or cylinders

• To control exhaust emissions

• To lubricate engine parts

What component of the fuel injector is responsible for controlling the fuel spray?

• The fuel pump

• The intake manifold

• The electrical connector

• The electromagnetic coil

How does the electromagnetic coil in a fuel injector function?

• It filters impurities from the fuel

• It compresses the fuel for better atomization

• It creates a magnetic field to lift the valve

• It generates heat to vaporize the fuel

What role does the magnetic core play in the fuel injector?

• It lubricates the valve

• It cools the injector

• It filters the fuel

• It amplifies and concentrates the magnetic field

What is the purpose of the spray disc in a fuel injector?

• To connect the injector to the fuel line

• To finely spray fuel into the engine

• To seal the injector

• To filter the fuel

Which component holds all parts of the fuel injector in place?

• The electrical connector

• The valve guide

• The metal ring

• The fuel line

What type of valve is NOT mentioned as being used in fuel injectors?

• Pin valve

• Rotary valve

• Con profile needle valve

• Spherical profile needle valve

What is a key feature of the valve guide in a fuel injector?

• It filters the fuel

• It is attached to the valve seat

• It amplifies the magnetic field

• It cools the injector

What is the concluding point of the fuel injector review?

• The need for fuel efficiency

• The importance of regular maintenance

• The role of the fuel pump

• The different types of valves used in injectors
