How an ATV Carburetor Works

Leave a Comment / knowledge / By

What Is a Carburetor?

A carburetor is a mechanical device that mixes fuel and air to allow for internal combustion. Its function is inspired by Bernoulli’s principle, which states that as air moves faster, its static pressure reduces, consequently increasing its dynamic pressure.

An ATV carburetor has an open pipe in the form of a 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.

How Does an ATV Carburetor Work?

Carburetors usually vary in terms of design and complexity. However, most of these mechanical devices function on the same basic principle- mixing air and fuel to promote combustion and consequently power the engine.

The failing pressure of the speeded-up air creates a much-needed sucking effect for the release of fuel.

This comes in extra handy when the engine is cold, running quite slow, or when it’s just starting up.

Here’s a quick summary of how the ATV carburetor works:

  • Air flows from the ATV’s air intake and into the top of the carburetor.
  • The air then passes through a filter that cleans potential debris, ensuring only clean air gets inside the carburetor.
  • When the ATV engine is started, the choke can be adjusted such that it strategically blocks the top of the pipe, thus reducing the total amount of air flowing inside the carburetor. This consequently increases the fuel content in the mixture that enters the cylinders.
  • The dip in air pressure helps create suction on the fuel pipe, which draws in the fuel.
  • The throttle, located at the bottom of the venturi, regulates the mixture of air and gas to allow the engine to produce more power, making the ATV move faster.
  • The air and fuel mixture then flows into the engine’s cylinders.
  • The fuel is continuously supplied to the mixture through the float-feed chamber.
  • The choke opens whenever the fuel level falls.

What Is The Brake Shoe?

Leave a Comment / blog / By

The brake shoe is a curved piece of metal used in drum brakes. Each brake shoe has friction material (known as brake lining) on one side.

The brake lining comprises of different types of heat resistant materials mixed with compounds like ceramic, brass, and graphite.

Brake shoes come in pairs and are usually bought in sets of four shoes — with two on each side.

You may notice one shoe in the pair has friction material that’s slightly shorter than the other. This is the primary shoe and faces the front of the vehicle. The secondary shoe, with more friction material, faces the rear.

Why is there a difference?

As the secondary shoe handles more braking than the primary shoe, it requires more friction material.

Now, let’s learn how brake shoes work.

How Brake Shoes Work In Drum Brakes

A drum brake system consists of a pan-shaped brake drum, a backing plate, brake studs, a hydraulic wheel cylinder and curved brake shoes. The friction material on the brake shoes faces outwards towards the inside of the brake drum.

Here’s what happens when you step on the brake pedal:

  • Force is converted into hydraulic pressure in the brake line from the master cylinder.
  • The hydraulic pressure through the brake line is transmitted by brake fluid, activating a piston in the wheel cylinder.
  • The piston pushes the brake shoes to contact the inside of the brake drum.
  • The brake shoes create friction with the brake drum, slowing the wheel.
  • When the brake pedal is released, stiff return springs retract the shoes to the original position.
  • A screw adjuster in the drum brake assembly extends gradually to compensate for worn brake shoes over time.

What about disc brakes?

The drum brake is a reliable braking system, though disc brakes (that use a caliper, brake pads, and rotor instead) have superseded it. You’ll still find a drum brake on the rear wheel of many cars because they’re cheaper to manufacture than disc brakes.

What about the parking brake?

The parking brake, or emergency brake, is operated from a lever via an emergency brake cable. When you pull the parking brake lever, it forces the brake shoes apart, the same way that hydraulics do.

In vehicles utilizing a drum brake system, the rear brake shoe pair performs the parking brake job. In cars with rear disc brakes, there’s usually a smaller drum brake in the brake rotor that performs a similar function.

What is an ATV Throttle Control

Leave a Comment / blog / By

An ATV (All-Terrain Vehicle) Throttle Control refers to the mechanism or device used to regulate the engine’s throttle on an ATV. The throttle controls the amount of fuel and air mixture that flows into the engine, determining the engine’s power output and ultimately controlling the vehicle’s speed.

ATVs typically have a hand-operated throttle control located on the handlebars. When the rider twists the throttle grip, it opens the throttle valve in the engine’s carburetor or throttle body, allowing more fuel and air to enter the combustion chamber. This increased fuel and air mixture leads to higher engine RPM (Revolutions Per Minute) and more power, causing the ATV to accelerate.

The throttle control is a critical component of an ATV, as it provides the rider with the ability to control the vehicle’s speed and maneuverability. It allows the rider to smoothly accelerate or decelerate as needed while riding on various terrains.

Moreover, modern ATVs may be equipped with electronic throttle controls, also known as “throttle-by-wire” systems. In these setups, the throttle grip is connected to sensors that send signals to the ATV’s engine control unit (ECU). The ECU then adjusts the throttle electronically, providing more precise control over the engine’s performance and enabling additional features like traction control and electronic stability control.

It’s essential for ATV riders to understand how to operate the throttle control safely and responsibly to ensure a smooth and enjoyable riding experience while minimizing the risk of accidents.

It’s essential for ATV riders to understand how to operate the throttle control safely and responsibly to ensure a smooth and enjoyable riding experience while minimizing the risk of accidents.

The role of ATV throttle control is to regulate the amount of power the engine produces and, consequently, the vehicle’s speed and acceleration. It is a fundamental mechanism that allows the rider to control the ATV’s movement while navigating various terrains and riding conditions. The throttle control plays a crucial role in the overall operation and safety of the ATV. Here are some specific roles and functions of ATV throttle control:

  1. Speed Regulation: The primary purpose of the throttle control is to adjust the engine’s RPM and, consequently, the speed of the ATV. When the rider twists the throttle, it opens the throttle valve, allowing more fuel and air into the engine. This leads to increased engine power, higher RPM, and faster acceleration. Conversely, releasing the throttle reduces power, RPM, and speed.
  2. Maneuverability: Proper throttle control enables the rider to maneuver the ATV effectively. When navigating through tight spots, rough terrain, or obstacles, a delicate manipulation of the throttle allows the rider to maintain the appropriate speed and control over the vehicle.
  3. Smooth Acceleration and Deceleration: A well-functioning throttle control allows for smooth and gradual acceleration, which is crucial for maintaining control over the ATV and preventing jerky movements that may lead to instability or accidents. Similarly, controlled deceleration helps bring the vehicle to a stop smoothly.
  4. Climbing and Descending: When tackling inclines or steep descents, the rider can adjust the throttle to match the terrain’s demands. For uphill climbs, a bit more throttle may be required to maintain momentum, while controlled throttle reduction helps control speed on downhill sections.
  5. Traction Control: Some modern ATVs come equipped with advanced electronic throttle control systems that provide traction control features. These systems can adjust the throttle response to prevent wheel slippage on slippery or loose surfaces, improving overall traction and stability.
  6. Fuel Efficiency: By controlling the throttle, the rider can manage fuel consumption. Riding at a steady speed with controlled throttle inputs can help conserve fuel and extend the ATV’s range.
  7. Safety: Proper throttle control is essential for safe riding. Sudden and aggressive throttle inputs can lead to loss of control, wheel spin, or accidents. Consistent and careful throttle management enhances the rider’s ability to respond to changes in the terrain or unexpected obstacles.

Overall, the ATV throttle control is a critical component that empowers the rider to navigate various environments safely and efficiently. Understanding how to use the throttle properly, in combination with other riding techniques, contributes to an enjoyable and secure off-road riding experience.
