DESCRIPTION
The Engine Piston Kit, identified by part number 4089842, is a set of components within the internal combustion engine that converts the energy produced by fuel combustion into mechanical power. The kit includes a piston, piston rings, wrist pin and circlips. Pistons are typically made from aluminum or cast iron and move up and down inside the cylinder bore to compress air/fuel mixture or gases during the combustion process. Piston rings provide a tight seal between the piston and cylinder wall to prevent loss of compression pressure and oil consumption. The wrist pin connects the piston to the connecting rod which transmits power to the crankshaft. The Engine Piston Kit is an essential component in any vehicle's engine system as it determines its performance characteristics such as power output, torque delivery, fuel efficiency and emissions levels.
