Engine piston connecting rod slight bending deformation symptoms include: unstable idle speed accompanied by shaking and vibration after engine starts; piston cylinder misalignment, as long as the connecting rod is deformed, the piston will generally experience uneven wear, causing abnormal noise after engine starts; cylinder leakage, resulting in insufficient cylinder pressure, engine misfire phenomenon, and severe shaking. Additional information about piston connecting rods is as follows: 1. Function of the connecting rod: The connecting rod connects the piston and the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft, and transmits the force received by the piston to the crankshaft. 2. Composition of the connecting rod: The connecting rod is generally composed of three parts: the small end, the rod body, and the big end.

How to Solve Low Engine Coolant Temperature?

Solutions for low engine coolant temperature: 1. Drive for a while to allow the temperature to rise, and try to avoid running the engine in high RPM zones; 2. Replace the thermostat. When the thermostat fails to close due to damage, it causes the engine cooling system to remain in a large circulation state at all times, ultimately leading to the engine temperature being too low and difficult to rise. When the engine starts cold, the coolant inside the engine is restricted to circulate within the engine water passages, which helps to quickly increase the engine temperature. When the engine reaches normal operating temperature, the thermostat opens (the thermostat acts as a valve for the engine's large and small circulation loops), allowing the coolant to flow from the engine water passages into the radiator. After being cooled by the radiator, it flows back to the engine to maintain the normal operating temperature of the engine.

How to Solve the Problem of Clogged Three-Way Catalytic Converter?

Solutions for clogged three-way catalytic converter: 1. Cleaning: During vehicle operation, exhaust gases from combustion can clog the three-way catalytic converter. Excessive clogging by impurities can reduce the converter's efficiency. Cleaning the converter to remove the clogged materials can restore its normal function. 2. Replacement: If cleaning does not restore normal function, replacement is necessary. The three-way catalytic converter is a device that converts harmful gases such as CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The core component of the three-way catalytic converter is a porous ceramic material installed in a specially designed exhaust pipe. The ceramic material itself does not participate in the catalytic reaction but is coated with precious metals such as platinum, rhodium, palladium, and rare earth coatings.
