Collection: Pistons
Pistons are essential components of an engine's combustion system. They are cylindrical-shaped metal pieces that move up & down inside the engine's cylinders. Pistons play a critical role in the engine's power generation process. When fuel & air are ignited in the combustion chamber, the resulting high-pressure gases push the piston downward, converting the energy into rotational motion through the engine's crankshaft. Pistons must be durable & capable of withstanding high temperatures, pressures, & repetitive motions. They are commonly made of aluminum alloy for its lightweight & heat-conducting properties. Pistons often have specific designs & features to optimize combustion efficiency & reduce emissions, such as valve reliefs, skirt coatings, & oil cooling galleries. Pistons must fit precisely within the cylinder bore to maintain proper compression & prevent any gas leakage. Regular inspection & maintenance of pistons are important to check for signs of wear, damage, or piston ring degradation, as worn or damaged pistons can lead to reduced engine performance, excessive oil consumption, or even engine failure. Upgrading to performance pistons can enhance engine performance, especially in high-performance applications. Proper lubrication & cooling are crucial for the optimal performance & longevity of pistons, as they rely on a consistent supply of clean engine oil & effective cooling systems to dissipate heat & reduce friction.
