Is the longer valve spring on the Teana for intake or exhaust?

[LukasAnn]

The longer valve spring on the Teana is for the exhaust. In terms of engine structure, valves are divided into intake valves and exhaust valves. Here is the relevant information: 1. Function of the intake valve: It draws air into the engine to mix with fuel for combustion. 2. Function of the exhaust valve: It expels the burned exhaust gases and dissipates heat. 3. Symptoms of damaged car valves: (1) It will affect the engine's efficiency, reducing the car's power; (2) It will produce abnormal noises, the engine may experience unstable idling or poor acceleration during operation, overtaking performance may also decrease. In severe cases, it can lead to difficulty starting the engine, failure to ignite, and the car may exhibit air leakage or increased carbon buildup.
