What does cold start mean for a car?

[LeLouis]

Cold start of a car refers to starting the engine when it has been shut down for a period of time and its internal temperature has reached the ambient temperature. In contrast, there is also hot start of the engine, which means starting the engine shortly after it was last shut down while there is still relatively high residual heat inside. Cold starting an engine is more difficult than hot starting, especially when the ambient temperature is very low and the fuel is diesel. Car ignition starting method: 1. Insert the key: Get in the car and insert the key, turn the key to the second power-on position for ignition, and wait for the system self-check to complete; 2. Start the car's engine: Shift the gear lever from P to N; release the brake and start the car's engine; 3. Start moving: Press the brake pedal with your foot, shift the gear lever from N to D, release the brake and press the accelerator to start moving.
