Are you looking for more information on Active Fuel Management and how it works? Active Fuel Management is a system essential to efficient and improved fuel economy. It is designed to increase the fuel-efficient operating capability of your vehicle while reducing emissions and preserving performance. This technology leverages advanced technology to operate the engine more efficiently while monitoring fuel supply, intake, combustion process and exhaust system. In this article, our focus will be on uncovering the inner workings of Active Fuel Management so that you can learn how to use this technology to your advantage. Keywords: Active Fuel Management, fuel economy, engine efficiency.
1. What is Active Fuel Management?
Active Fuel Management is a system developed by General Motors (GM) that prevents the engine from running on all-cylinder mode during certain conditions. Rather than using the traditional valleys or hills of an eight-cylinder engine when the driver does not need the full power, AFM shuts off four of the cylinders when full power is not needed. This helps conserve fuel, increase the life of the engine, and increase its reliability.
The AFM system is comprised of the following components:
- Solenoid Actuator: Connects to the engine’s intake to control cylinder deactivation
- Electronic Control Module (ECM): Monitors, computes, and coordinates engine parameters to make sure AFM works properly
- Various Sensors: Used to monitor engine conditions and provide inputs to the ECM
It is important to note that AFM will only engage when the driver requires less power, such as when cruising down a highway or when the vehicle is at rest. When more power is required, such as when accelerating to merge onto a highway, the system will automatically revert back to all-cylinder mode.
2. Benefits of Active Fuel Management Technology
More Efficient Vehicle Performance
Active fuel management technology serves as a substantial way to improve fuel economy without having to sacrifice performance. This technology allows a vehicle’s engine to switch between different cylinder configurations depending on the driving situation. With the ability to switch between 8 or 4 cylinder modes, the car can anticipate and meet driving needs more efficiently. This contributes to a decreased need for fuel, creating better fuel economy ratings over the long-term without sacrificing the power of the engine.
Reduction in Harmful Emissions
Vehicles equipped with active fuel management technology produce fewer emissions, leading to improved air quality and environmental impacts. This auto technology allows for a reduction in pollutants and a more efficient burning of fuel, translating to fewer emissions of pollutants such as nitrogen and carbon dioxide. Cars that have active fuel management technology can reduce their carbon dioxide emissions by up to 15% and can reduce nitrogen oxide emissions by up to 20%.
3. How Does Active Fuel Management Work?
Active Fuel Management, or AFM, is a technology that allows a car to switch between two different sets of cylinders depending on the driver’s needs. When the car is not being used as intensely, or in cases like cruising on highways, fewer cylinders are used and fuel efficiency is improved.
How does it work? The AFM system operates with a series of valves, an intake manifold, and an electronic control module. When the car is idle or cruising, the control module tells the valves to shut off the unused cylinders in the engine, resulting in improved fuel efficiency. When the driver needs more power, the system opens up the valves and activates the unused cylinders to give the car greater power.
The benefits of this system are numerous as it can significantly improve overall fuel efficiency. Additionally, it helps maintain the vehicle’s performance since the car only activates the cylinders when more power is required. With AFM, drivers can enjoy better fuel economy and improved power in the same engine.
4. What are the Advantages of Active Fuel Management?
Active Fuel Management (AFM) offers many advantages for drivers who are looking for added fuel-efficiency without sacrificing performance. It’s becoming increasingly popular for those looking to maximize their miles per gallon.
Improved Fuel Economy – Perhaps the biggest advantage of AFM is better fuel economy. This technology helps reduce fuel consumption by automatically switching between four- and eight-cylinder modes, depending on driver demand. The result? You get the power of a V8 engine without the fuel costs of a larger engine.
- You will enjoy an EPA-estimated 2-4 more miles per gallon when using AFM.
- AFM will help your engine run more efficiently and last longer.
Reduced Emissions – Since AFM reduces the amount of fuel used, it also helps to reduce emissions. This helps to reduce your environmental footprint, and helps ensure cleaner air for everyone.
- AFM technology can reduce CO2 emissions by up to 13.5%.
- It can reduce other pollutants such as HC, NOX, and CO by up to 20%.
Q&A
Q1: What is Active Fuel Management?
A1: Active Fuel Management is a technology that allows an engine to switch between two or more combustion modes. It can switch between different numbers of cylinders to improve fuel economy and reduce emissions from the engine.
Q2: How does Active Fuel Management work?
A2: Active Fuel Management works by monitoring engine load, speed and torque. When the engine’s load is light, it switches to a lower number of cylinders and reduces fuel consumption. When the load increases, the engine switches back to the full number of cylinders for increased power and torque.
Q3: What are the benefits of Active Fuel Management?
A3: Active Fuel Management helps improve fuel efficiency and reduce emissions. This can result in lower fuel bills and a smaller environmental footprint. It is also beneficial for vehicles that mainly operate at low engine speeds such as city driving.
