Why is Cold Starting Difficult for Vehicles?

[LaEmersyn]

There are several reasons why a car may have difficulty starting in cold conditions: 1. The engine temperature is too low, indicating that the internal temperature of the engine is insufficient, and the internal oil and lubricants have not reached their optimal lubrication state. In low-temperature conditions, the engine's ignition capability decreases, leading to difficulty in starting. 2. If the car is used for a long time without timely cleaning, the engine is more prone to carbon buildup. The accumulated carbon can easily clog the exhaust pipe and also absorb fuel, reducing the engine's efficiency. For example, if the engine control unit injects 100% fuel, only 90% may actually be used, with the remaining 10% absorbed by carbon deposits. This results in difficulty starting the engine. To ensure better engine performance, it is recommended to pay attention to regular maintenance and periodically clean the engine's carbon deposits.
