Have you ever wondered if turbocharging your engine actually helps save gas? Many people assume that turbocharging increases fuel efficiency, but the impact of turbocharging on mileage is more complex than it seems. Let’s take a closer look at how turbochargers work and their effect on gas mileage.
What Is a Turbocharger?
You may have heard the term “turbocharger” before but not totally understand what it is. A turbocharger uses exhaust gas to spin a turbine that compresses air into your engine’s intake manifold. This allows more air and fuel into the combustion chamber, boosting the power output of your engine. Turbochargers let smaller engines produce the power of larger, naturally aspirated engines while using less fuel. That’s why they can improve fuel efficiency if used correctly.
What Are the Potential Benefits?
At first, turbocharging seems like an easy way to boost fuel economy. You can get the same power from a smaller, more efficient engine. However, there are some key things to keep in mind. Turbo engines often require higher octane fuel, which costs more. The increased combustion temperatures can also lead to more emissions and lower efficiency. And don’t forget – more power can tempt you to drive more aggressively, accelerating faster and going higher speeds. That puts more load on your engine, burning more fuel.
When Do Turbos Increase Efficiency?
While turbocharging isn’t a magic bullet, it can improve mileage when used properly. At low speeds and loads, the turbo lets your engine use less fuel for the same power. It only kicks in at higher loads when you need more airflow. This allows for a smaller, more efficient overall engine size. Turbos work best for fuel economy with smaller engines powering heavy vehicles like trucks. The turbo provides power for hauling and passing without requiring a huge engine. According to Progressive, turbochargers give your car extra power without increasing the size of the engine. This typically makes them more fuel-efficient than larger engines.
With mindful driving habits, a properly maintained turbocharged engine can deliver better mileage. The key is avoiding excessive boost by easing off the gas pedal whenever possible.
