Does Revving Engine Help Jump Start a Car?
Introduction
When a car’s battery is dead, it can be frustrating and inconvenient. One common method for jump starting a car is to use another car’s battery and jumper cables. However, some people believe that revving the engine of the car that is providing the jump start can help the process. Is this actually true?
How Jump Starting Works
Before we can answer the question of whether or not revving the engine helps jump start a car, we need to understand how jump starting works. When a car’s battery is dead, it means that the battery is not able to provide enough power to start the car’s engine. This can be caused by a number of factors, such as leaving the headlights on overnight or having a faulty alternator.
Jump starting a car involves connecting the dead battery to another car’s battery using jumper cables. This allows the good battery to provide power to the dead battery, which in turn starts the car’s engine.
Does Revving the Engine Help?
The answer to the question of whether or not revving the engine helps jump start a car is: it depends. In some cases, revving the engine can help to increase the voltage output of the good battery, which can make it easier to start the car. However, in other cases, revving the engine can actually make it more difficult to start the car.
If the dead battery is completely discharged, then revving the engine will not help. This is because the good battery will not be able to provide enough power to start the car, even if the engine is revving.
However, if the dead battery is only partially discharged, then revving the engine can help. This is because the good battery will be able to provide more power to the dead battery when the engine is revving.
When to Rev the Engine
If you are trying to jump start a car, you should only rev the engine if the dead battery is only partially discharged. If the dead battery is completely discharged, then revving the engine will not help.
To determine if the dead battery is only partially discharged, you can try to turn on the car’s headlights. If the headlights turn on, then the battery is only partially discharged and you can try revving the engine. However, if the headlights do not turn on, then the battery is completely discharged and you should not rev the engine.
Conclusion
Revving the engine can help jump start a car in some cases, but it is not always necessary. If the dead battery is completely discharged, then revving the engine will not help. However, if the dead battery is only partially discharged, then revving the engine can help to increase the voltage output of the good battery, which can make it easier to start the car.
