Since its very introduction, the electric starter on your car has had two jobs: Primarily, to spin the flywheel to start the engine. This technology is more than just a starter that spins the engine to a start more frequently, as you’ll soon find out, but the starter is the single most important component. When the system senses that the driver is taking her foot off the brake, it restarts the engine while the transmission is still in gear. In general, auto-stop/start senses that the vehicle has come to a stop, that the engine RPM has fallen either to a full stop or close to it, and that the brake is depressed.Īt that point, the system shuts the engine down, and disengages the transmission.
It supplies the technology to all three American manufacturers, as well as vehicles in Land Rover, Audi, Fiat, Hyundai, Toyota, and Volvo’s product lines. There are a few different suppliers of such technology, but one of the the biggest is Denso. If your commute consists of a single stoplight and a long stretch of highway, Auto-Stop/Start isn’t going to save a lot of fuel, but if you’re like most of us, with a ton of stop-and-go traffic on your way to and from the office, it can make a significant difference in your fuel economy, typically between three and five percent. A combination of aerodynamics, weight savings, electrification, hybrid technologies and advanced engine management software has gone a long way, but it doesn’t take a rocket scientist to understand that you save a lot of fuel when the car isn’t running at all.įind a Hybrid with Auto-Stop/Start Technology at Īuto-Stop/Start technology automatically shuts the engine off when the vehicle comes to a full stop, and then starts it again when the driver wants to get moving. Since the Obama Administration finalized standards in 2012 to encourage the automotive industry to reach a 54.5 miles per gallon corporate fuel economy average by 2025, manufacturers have been employing every means possible to squeeze another mile out of a gallon of gasoline.
What Is Auto-Stop/Start Technology and Why Do We Need It? Now that we’ve arrived at a point when most new cars have auto-stop/start technology which increases the number of starts in an average commute by 100x, are we more vulnerable to engine and component failure? Even if the extent of your automotive technical knowledge begins and ends with prime time television commercials, you probably understand that the most engine wear takes place when you start your car.
