Description

Ingco EY20 Piston

The EY20 piston is a replacement part for the EY20 Piston, a horizontal four-stroke gasoline engine commonly used in lawnmowers, generators, and other outdoor power equipment. The engine has a displacement of 183cc and a net horsepower of 5.5.

The piston is a cylindrical component that moves up and down within the engine’s cylinder. It’s connected to the crankshaft by a connecting rod and is responsible for compressing the air-fuel mixture in the cylinder before ignition.

If you’re looking for an EY20 piston, you can find them from a variety of online retailers, including [places that sell EY20 pistons]. Be sure to check the specifications of the piston before you buy it to make sure it’s the right one for your engine.

The EY20 piston is the heart of your  EY20  piston, a critical component responsible for converting gasoline’s energy into usable power. Here’s a closer look at its key features and functions:

Construction:

• Made from high-strength aluminum alloy for durability and efficient heat transfer.
• Features a smooth cylindrical body with a slightly domed top for optimal combustion chamber shape.
• Includes piston rings that fit into grooves around the piston’s circumference. These rings:
  • Seal the combustion chamber, preventing leakage of the air-fuel mixture and hot exhaust gases.
  • Help transfer heat from the piston to the cylinder wall.

Dimensions:

• Typically has a diameter of 67mm (check your engine manual for exact specifications).
• The overall length will vary depending on the specific design, but it accommodates the connecting rod attachment and allows for proper piston travel within the cylinder.

Functionality:

1. Intake Stroke:

   • The piston moves down the cylinder, creating a vacuum.
   • The intake valve opens, drawing in an air-fuel mixture through the carburetor.
   • The piston rings ensure the mixture stays within the chamber.

2. Compression Stroke:

   • The piston moves back up the cylinder, compressing the air-fuel mixture.
   • This compression increases pressure and temperature, creating ideal conditions for combustion.
   • The piston rings again play a crucial role in maintaining pressure within the chamber.

3. Combustion Stroke:

   • The spark plug ignites the compressed air-fuel mixture, causing a rapid expansion of hot gases.
   • This expansion forces the piston down the cylinder with tremendous force.

4. Exhaust Stroke:

   • The piston travels back up the cylinder, pushing the burnt exhaust gases out through the open exhaust valve.
   • The piston rings again ensure a proper seal, preventing exhaust from leaking back into the combustion chamber.

Maintenance:

• The EY20 piston, like any engine component, experiences wear and tear over time.
• Regular maintenance checks are recommended to ensure optimal performance and prevent engine damage.
• Signs of a faulty piston include:
  • Loss of power
  • Increased oil consumption
  • Knocking sounds from the engine

If you suspect a problem with your EY20 piston, consult a qualified engine mechanic for diagnosis and potential replacement.
