ONE technology seeing more and more adoption in vehicles is the stop-start button.

What is the stop-start button?

The stop-start button is part of the engine system. It shuts off a vehicle’s engine when it’s not in use. This improves fuel economy and reduces pollution. The engine starts again when the clutch is engaged or the brake is released.

However, not all stop-start systems are created equal. Some systems are slow and need a bit more forethought from the driver – especially if you need to put your foot down – while others react as your foot hits the accelerator. All in all, the technology is getting better.

How does it work?

The system uses a computer to detect when the car is stationary or the car is out of gear and it cuts power to the spark plug. The ignition automatically starts again when the vehicle begins moving forward, the accelerator is used or the clutch is pressed.

While the process happens automatically, many systems allow drivers to choose whether the system is active or disabled by pushing the car’s stop-start button.

The environment benefits most from a stop-start system because of the drop in pollution.
