What is Chevy Active Fuel Management?
Chevy Active Fuel Management (AFM) is a technology developed by General Motors to improve fuel efficiency in Chevrolet vehicles. It works by temporarily deactivating some of the engine's cylinders when full power is not needed, reducing fuel consumption and emissions.
How Chevy Active Fuel Management Works
Chevy AFM is designed to seamlessly transition between using all of the engine's cylinders and only using a subset of them, depending on the driving conditions. When the vehicle is operating under light load, such as cruising on the highway, the system can deactivate up to half of the engine's cylinders. This reduces the amount of fuel being consumed, leading to improved fuel economy.
The system uses various sensors to monitor the vehicle's operating conditions, such as engine load, speed, and throttle position. When the conditions are right, the AFM system will automatically deactivate the appropriate cylinders, and then reactivate them when more power is needed.
Benefits of Chevy Active Fuel Management
- Improved Fuel Efficiency: By deactivating cylinders when they are not needed, Chevy AFM can improve fuel economy by up to 7% in certain driving conditions.
- Reduced Emissions: With less fuel being consumed, Chevy AFM also helps to reduce the vehicle's emissions of greenhouse gases and other pollutants.
- Seamless Operation: The transition between using all cylinders and only a subset is designed to be imperceptible to the driver, ensuring a smooth and consistent driving experience.
Chevy Active Fuel Management is available on a variety of Chevrolet models, including the Silverado, Tahoe, Suburban, and Corvette. It is an important technology that helps Chevrolet vehicles achieve better fuel efficiency and lower emissions without compromising performance or driving dynamics.
