Why does the car have more power when cold but less when hot?
1 Answers
If the car runs powerfully when cold but loses power when hot, it is mostly due to an overly rich air-fuel mixture. Additional information is as follows: 1. Suggestion: Remove the spark plugs and observe the color of the insulator. If it appears smoky black, it indicates an overly rich mixture causing poor combustion. If it is slightly brick red, the mixture concentration is normal. If it appears white, the mixture is too lean. 2. Air-fuel mixture: The air-fuel mixture (gas-mixture) refers to a gas containing two or more effective components, or non-effective components exceeding the specified limits. It is a mixture of several gases commonly used as a working medium in engineering. Mixed gases are usually studied as ideal gases.
