The starting of a car takes time in winter, because the__________________?
Correct answer: A. Vaporisation of the fuel is decreased
- A. Vaporisation of the fuel is decreased
- B. Fuel supply for ignition is not sufficient
- C. Octane number of fuel is decreased
- D. Pour point of fuel decreases
Explanation
Cold weather reduces the vaporisation of fuel, so less fuel vapour mixes with air for ignition and the engine takes longer to start. Octane number is not the main cause of this winter-starting difficulty.
