What Causes the Abnormal Noise During Cold Start of the Teramont?

[DiJude]

When the Teramont is started cold, an abnormal noise can be heard from the engine compartment. In fact, this noise occurs because the oil pump has not yet fully built up oil pressure during a cold start, resulting in insufficient lubrication for various components. Under normal circumstances, the abnormal noise will disappear after the engine has been running for a while. Extended content: The function of the carbon canister purge valve is that when the engine starts, the solenoid valve installed between the carbon canister and the intake manifold opens, allowing the gasoline vapor adsorbed in the carbon canister to be drawn into the cylinders along with air for combustion. This not only reduces emissions but also lowers fuel consumption.
