Fuel Injection System Introduction

A small nozzle which are controlled electronically to atomize fuel under high pressure into an engine’s combustion chamber.

• Carburetors

• Fuel Injectors

• Spark Plug

• Intake Valve

Which one not belong to 4-stroke engine cycle?

• Intake

• Power

• Air/Fuel Mixtures

• Compression

Creating the explosion which makes your engine produce power.

A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.

A device for delivering electric current from an ignition system to the combustion chamber.

A valve that controls the passage of fluid or air into a pipe, channel, or duct

What is the purpose of the fuel injector?

• ^{To deliver fuel into the engine cylinders}

• ^{To deliver air into the engine cylinders}

• ^{To deliver air & fuel into the cylinders}

• ^{To deliver burned gases into the cylinders}

The part is where the fuel is stored.

• Fuel Intake Manifold

• Fuel Filter

• Cylinder block

• Fuel Tank

Injector located inside throttle body, sits on top of inlet manifold.

• Direct Injection

• Multiport Fuel Injection

• Single Point Fuel Injection

• Sequential Fuel Injection

Fuel is injected directly into the combustion chamber, past the valves.

• Single-Point Injection

• Port Injection

• Sequential Injection

• Direct Injection
