Start stop system - operation

Modern motoring increasingly relies on technologies that are supposed to reduce fuel consumption and exhaust emissions. One such solution is the start-stop system, which has become almost a standard in new cars. Although it is a seemingly simple function, its operation, effectiveness and impact on driving comfort and vehicle operation raise many questions. How exactly does the start-stop system work, what does the start-stop system provide, what are its disadvantages and how can it be deactivated? Let's check.

How does the start-stop system work?

Many owners of modern cars are not aware of how the start-stop system works. The start-stop system is electronic system, the aim of which is automatic engine shutdown and restart when the vehicle is stationary – most often at traffic lights or in a traffic jam. Thanks to this, when the car is not moving, does not consume fuel, which translates into lower CO2 emissions and less resource consumption.

In practice, when the driver stops the vehicle and presses clutch pedal (in cars with manual transmission) or brake pedal (for models with automatic gearbox), start-stop system is activated and leads to engine shutdown. As soon as the driver presses the clutch pedal or takes your foot off the brake – it happens engine restart and the car is ready to continue driving.

When does the start-stop system work properly?

Although the operation of the system seems simple, in practice it depends on many factors. Start-stop system in a car only works when certain technical and environmental conditions are met. Here are the most important ones:

Engine temperature – too low or too high may prevent the system from operating.
Battery charge level – If the battery is too weak, the system will not work.
Heated windows and other burdensome functions electrical system can deactivate the system.
Outside temperature – in severe frost the system may be switched off automatically.
Seat belts fastened, closed door.

This is why it happens that the system doesn't work despite the vehicle being stopped. This is not a fault, but the effect of safeguards that are designed to protect drive unit and driver comfort.

What does the start-stop system provide?

Start-stop function First of all, it provides fuel savings – especially in urban conditions, where frequent stops are the norm. In theory, the system can reduce fuel consumption even by 5–10% in the urban cycle. Additionally, thanks to the start-stop system:

is decreasing exhaust emissions, which is beneficial for the environment,
the overall efficiency of the vehicle improves,
the car is more environmentally friendly – which may affect usage fees in some cities.

When does the system not start?

Many drivers notice that start-stop system doesn't always work. This is often the result of not meeting the conditions mentioned earlier. Additionally, problems can result from:

sensor faults responsible for monitoring vehicle parameters,
too low battery voltage,
deep discharge of the system,
control software errors.

In such situations, dashboard appropriate information about system inactivity may appear.

Deactivating the start-stop system

Many people ask themselves the question – is it possible turn off the start-stop system? The answer is yes, but it is not always a permanent solution. Most manufacturers provide dedicated button to temporarily disable the system – but only until the engine is restarted. After the next start, this function reactivates.

That is why more and more drivers are looking for alternative methods of deactivation – especially those who feel that the system reduces driving comfort or negatively affects the technical condition of the vehicle.

Disadvantages of the start stop system

Although the start-stop system has many advantages, is not free from defects. Above all:

Frequent engine shutdowns may lead to faster wear of some components – among others starter, battery, and even exhaust system.
For many drivers, the system reduces driving dynamics, especially when moving off quickly.
Engine start may not be instantaneous – which is especially noticeable in older vehicles or when the battery charge is low.
The system may not function predictably – which can sometimes be irritating.
In addition, when driving in traffic jams, the constant automatic engine shutdown and start may be more troublesome than useful.

Some users also complain about increased fuel consumption in situations where engine restart occurs very often.

ZENBOX PRO – deactivate the start-stop system in the blink of an eye

If you are one of the drivers who would like to disable the start-stop system permanently, the ideal solution may be a device ZENBOX PRO. This is a modern electronic module that allows permanent deactivation of the start-stop function – without having to interfere with the vehicle electronics or void the warranty.

ZENBOX PRO works in a simple and safe way – after its installation, the start-stop system remains inactive until the driver will decide whether to turn it on again. This makes it possible to:

behavior full control over engine starting,
elimination of problems with driving dynamics,
protection of elements such as battery, starter Whether electrical system,
improvement comfort driving – especially in urban conditions.

Thanks ZENBOX PRO, drivers can adjust the vehicle's behavior to their own preferences - without having to daily deactivation of the start-stop function using a button. This solution is gaining popularity and responds to the real needs of users of modern cars.

Importantly, ZENBOX PRO does not require complicated configuration or applications. Professional assembly ensures safety, and the device works completely automatically.
