NICHE CYLINDER

  • ATV engines come with either one or two cylinders
  • Displacements typically measuring between 100cc and 800cc
  • It's important to note that safely riding an ATV requires a certain amount of body weight and physical strength
  • Disaster can strike, for example, when a young rider uses an overpowered or a larger ATV

NICHE PISTON

An ATV piston is a component of engines, pumps, and gas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft through a piston rod and or connecting rod

Piston Anatomy

A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head.

Piston Components

ATV Piston components include the piston head, piston pin bore, piston pin, skirt, ring grooves, ring lands, and piston rings. The piston head is the top surface of the piston which is subjected to tremendous forces and heat during normal engine operation

NICHE GASKET

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

Some Types of Gaskets:

  • Head gaskets create a seal between the engine block and cylinder head. This seal establishes a proper compression and prevents fluid leaks into the cylinders
  • Base gaskets create a seal between the top-end of your engine and the engine cases. Stop pesky engine oil leaks before they cause permanent damage to your engine.
  • The valve cover is sealed to the upper section of the engine cylinder head by a valve cover gasket. As it passes around the camshafts, rockers, and valves, the gasket stops engine oil from seeping out.

NICHE BRAKE CALIPER

Where?

  • A brake caliper straddles each rotor in the front, which is mounted to the wheel hub

How many?

  • While many ATVs have 4 brake calipers, 1 for each wheel, it is not uncommon for an ATV to have only 3 calipers.

How it works?

  • When the brakes are applied, brake fluid is pushed from the master cylinder to the caliper piston. The force of the brake fluid causes the piston to apply pressure to the brake pads, which then squeeze the rotor. The friction and heat created by the brake pads on the rotor creates a drag on the rotor
