How does a carburetor work?

A carburetor’s job is to supply an internal combustion engine with air/fuel mixture

A carburetor works by mixing air and fuel to allow for internal combustion.

Pros of using carburetors

  • Carburetors aren’t costly when compared to that of a fuel injector
  • The operating mechanism of carburetors is straightforward.
  • Carburetors aren’t integrated into engines, which means they can be replaced or serviced without affecting the engine.
  • Air and fuel mixture is perfectly done with the component.
  • It has more power and precision of the air/fuel mixture.

Functions of carburetors

  • The primary function of a carburetor is to allow a suitable amount of air and fuel needed to produce power.
  • It regulates the air-fuel ratio and also mixes the fuels.
  • Controls the engine speed.
  • Helps the fuel to burn smoothly and properly without any problem.

NICHE Careburetors

ATV Carburetors:

Most ATV carburetors use a simple design. They have a vertical air pipe that’s strategically located above the engine cylinders. The vertical air pipe is then joined to a horizontal fuel pipe (at the narrowest part of the venturi) which allows for the passage of air into the engine’s inlet manifold. The inlet manifold, also called the intake manifold, is part of the engine that supplies the air/fuel mixture to the cylinders

Motorcycle Carburetors:

Regulate the flow of air through their Main bore (Venturi), this flowing air draws in fuel and the mixture enters the engine via the intake valve.Turning the throttle on a motorcycle handlebar does not directly control how much fuel enters the engine. The throttle controls how much air is allowed to flow through the carburetor, and the flow of air is what controls how much fuel is also fed into the engine

Fuel Pump Kit

A fuel pump is a part that supplies fuel from a fuel container to the carburetor. A fuel pump is an important part of the engine because the fuel supply is important to keep the engine running.

  • The pressure of the fuel must align with the requirements for the engine to operate normally.
  • If the pressure is too low, the engine will run out of fuel, causing the engine to stall, hesitate, or misfire.
  • If the fuel pressure is too high, the engine will not run properly, and fuel will be wasted.

Some signs of a bad fuel pump:

  1. Difficult Start
  2. Engine Stalling or Actual Stall
  3. Lower Fuel Efficiency
