Does Car Heater Increase Engine Ventilation?
It’s a common misconception that turning on your car heater will increase engine ventilation. In fact, the opposite is true. When you turn on your heater, the blower motor draws air from the interior of the car and blows it through the heater core. This air is then heated by the heater core and blown back into the interior of the car. As a result, the air in the car is recycled and there is no increase in ventilation.
How Does a Car Heater Work?
A car heater works by using a heat exchanger to transfer heat from the engine coolant to the air inside the car. The heat exchanger is typically a small radiator that is located in the dashboard or under the front seat. The coolant flows through the heat exchanger, and the air from the blower motor is blown over the heat exchanger. As the air passes over the heat exchanger, it is heated and blown back into the interior of the car.
Why Doesn’t Turning on the Heater Increase Ventilation?
When you turn on the heater, the blower motor draws air from the interior of the car. This means that there is no fresh air being brought into the car. As a result, the air in the car is recycled and there is no increase in ventilation.
How Can I Increase Ventilation in My Car?
There are a few things you can do to increase ventilation in your car:
- Open the windows.
- Use a sunroof. If your car has a sunroof, opening it can help to increase ventilation. However, sunroofs can also let in a lot of heat, so be sure to close them when you’re not using them.
- Install a roof vent. A roof vent can help to draw air out of the car, which can increase ventilation. However, roof vents can be expensive to install and can also make your car more noisy.
Conclusion
Turning on your car heater will not increase engine ventilation. In fact, the opposite is true. If you want to increase ventilation in your car, you should open the windows or use a sunroof. You can also install a roof vent, but this can be expensive and may make your car more noisy.
