How Does Stop-Start Technology Work?

Although they have existed for roughly 30 years, and there have been several concerted efforts to push the technology to the masses, stop-start systems have just started to become more popular in our cars. In fact, if you look at new-release vehicles coming to the market today, a fair portion of them are now banking on the technology, and that is outside the luxury segment of the market as well.

With a growing focus on fuel efficiency and sustainable driving, it’s little surprise that it’s only now we are starting to see this shift. According to manufacturers, motorists can save up to 10% on fuel efficiency. Despite this, in terms of practicality, motorists haven’t quite warmed to the technology. Let’s consider the ins and outs in a little more detail.

What is a stop-start system?

Stop-start systems are a mechanism that is designed to control the operation of the engine. The purpose is to ensure that the engine is only functioning when the car is moving, and not when it is sitting idle. Therefore, when the car is sitting idle, like at traffic lights, the system will automatically turn off the car’s engine. The technology relies on a myriad of sensors to determine things like brake pressure, vehicle speed, gear changes and more. Once you are ready to move again, the system reactivates the engine.

You might be wandering, doesn’t a system that turns the engine off interfere with other functions of the car? Fortunately, the technology includes a bypass that enables things like air conditioning and the like to continue. Unlike some of the earlier iterations of the technology, or even examples from early last decade, today’s systems are ‘smart’ enough to react to changes in driving conditions, such that your car runs smoothly.

In the past there has also been concern around the potential for excessive wear that comes with stop-start technology. While there is no shying away from the fact that the more stop-start scenarios one endures, the more strain you put on various mechanical parts, manufacturers have found ways to mitigate if not offset this altogether. A large part of that strategy relies on a heavy duty starter and battery, while engine bearings are also lubricated to reduce friction with the crankshaft. So you don’t necessarily need to not worry on that front.

 

Does the technology help address emissions?

So when it comes to improvements, in the majority of instances where a vehicle is idle for longer than a minute, stop-start technology will deliver fuel savings. Of course, however, there are more permutations to consider, so it’s not possible to say that there will be benefits in every scenario, particularly once driver behaviour starts to play a role in things.

While the prospect of fuel savings is something that can only help your hip pocket, don’t forget that replacement parts or repairs to the system could set you back more than you might otherwise normally be up for. Nonetheless, with the sheer volume of fuel that goes into our cars these days, an estimated 10% reduction is nothing to sneeze at, even if (most) ‘motorheads’ would prefer to have that engine ticking along at all times. http://credit-n.ru/offers-zaim/denga-zaimy-nalichnimi.html
