Induction System

The system that brings in air from outside, mixes it with fuel, and delivers the fuel-air mixture to the cylinder for combustion.

Carburetor System

A type of induction system that mixes fuel and air in the carburetor before this mixture enters the intake manifold.

Float-Type Carburetor

The most common type of carburetor, featuring systems for idling, accelerating, mixture control, idle cutoff, and power enrichment.

Disadvantages of Float-Type Carburetors

They do not function well during abrupt maneuvers.

Low-pressure fuel discharge causes incomplete vaporization and difficulty in some supercharged systems.

It has an icing tendency.

Pressure-Type Carburetor

A carburetor that discharges fuel into the airstream at a pressure above atmospheric pressure.

Carburetor Icing

Occurs due to fuel vaporization and a decrease in air pressure, resulting in a sharp temperature drop in the carburetor.

Carburetor Heat System

A system used in engines with float-type carburetors to combat the effects of carburetor icing.

Fuel Injection System

A system where fuel is injected directly into the cylinders or just ahead of the intake valve, using an air intake similar to that of a carburetor system.

Basic Components of Fuel Injection Systems

Engine-Driven Fuel Pump, Fuel-Air Control Unit, Fuel Manifold, Discharge Nozzle, Auxiliary Fuel Pump, and Fuel Pressure/Flow Indicator.
