What is the Piston Connecting Rod Assembly Composed Of?
2 Answers
Piston connecting rod assembly is mainly composed of piston, piston ring, piston pin, connecting rod and connecting rod bearing, etc. Here is some relevant knowledge about the piston connecting rod assembly: 1. Working process of the piston connecting rod assembly: The piston connecting rod assembly converts the reciprocating motion of the piston into the rotational motion of the crankshaft, while transforming the force acting on the piston into the torque output by the crankshaft to drive the car wheels. It is the transmission component of the engine, which transmits the pressure of the combustion gas to the crankshaft, causing the crankshaft to rotate and output power. 2. Function of the compression ring: The function of the compression ring is to ensure the seal between the piston and the cylinder wall, preventing high-temperature and high-pressure gas from entering the crankcase; at the same time, it also conducts most of the heat from the top of the piston to the cylinder, which is then taken away by the cooling water or air.
The piston connecting rod assembly is one of the core components of an automobile engine, mainly including the piston, piston pin, piston rings, and connecting rod. The piston moves up and down in the cylinder to compress the air-fuel mixture; the piston rings are responsible for sealing, preventing oil leakage and gas ingress; the piston pin connects the piston and the connecting rod, ensuring smoother motion; the connecting rod converts the up-and-down motion of the piston into the rotational force of the crankshaft. Having driven for decades, I've found that these parts are prone to wear due to high temperatures or oil starvation. For example, aging piston rings can cause oil burning, leading to a sharp increase in fuel consumption. Regularly changing to high-quality engine oil can significantly extend their lifespan. Otherwise, the engine may fail prematurely, and repairs can be extremely costly.
