Mercedes-Benz Passenger A0020309524 Piston Ring

Description

The Mercedes-Benz Passenger piston ring is a precision component that fits into engine crankcase piston assemblies to seal combustion chambers. It is used in high-performance gasoline and diesel engines to maintain compression and control oil consumption. This ring offers superior wear resistance, excellent sealing, and consistent performance under extreme temperatures. It measures 20 x 130 x 130 mm and is manufactured in Germany.

Key Features & Benefits

Piston rings basically seal the gap between the piston and the cylinder wall inside your engine. There are usually a few different rings per piston – typically one or two compression rings and then an oil control ring. The compression rings, as the name suggests, keep the combustion pressure inside the cylinder where it belongs, so you get the power you need. The oil ring’s job is to scrape excess oil off the cylinder walls and return it to the oil pan. It prevents oil from getting into the combustion chamber and burning, which would cause smoke and reduce efficiency. Think of the piston rings as being crucial to how efficiently your engine runs. They directly impact horsepower, fuel economy, and oil consumption. They work with the piston as it goes up and down in the cylinder, constantly sealing and managing those gases and fluids. A healthy set of rings keeps everything running smoothly, giving you the power when you press the gas pedal and ensuring the engine isn’t wasting oil.

Symptoms, Risks & Replacements

Well, if piston rings wear out or break, you’ll notice it. You'll likely see blueish smoke coming from your exhaust—that's oil burning. You'll probably also experience a loss of power and a drop in fuel economy. Over time, worn rings can lead to more serious engine damage because the increased friction and oil consumption can really take a toll. It’s something you definitely want to address before it gets worse. If you're doing an engine rebuild or just need to freshen things up, new piston rings are essential. You can find a good selection of them at places like Fixparts Online, and getting the right set for your specific engine is key.
