Start-Stop Technology

Start-Stop technology is based on the principle on nonoperation of internal combustion engine (ICE) where unnecessary. Therefore, idling time of internal combustion engine is minimized and fuel saving and reduction of CO2 emission are ensured.

Today, energy required to start a modern gasoline-powered internal combustion engine corresponds to energy that idling engine consumes in 0,7 seconds. Therefore, closing internal combustion engine during each stop for more than 0,7 seconds will ensure fuel saving.

Start-Stop (s-s) vehicles are different from each other. While some vehicles ensure kinetic energy of vehicle is stored in battery with recovery braking, some are not equipped with recovery braking feature. While 5% of reduction in fuel consumption and CO2 emissions is ensured in vehicles without recovery braking, this rate reaches about 10% in vehicles with this feature. (These values are obtained as a result of European inner-city circulation tests)

Due to emission standards that are becoming stricter year by year, it is expected that majority of vehicles to be manufactured in future years will have start-stop.

HOW DO START – STOP VEHICLES (MICRO HYBRID) OPERATE?

In a manual-transmission vehicle that uses Start-Stop system, internal combustion engine is stopped if following three conditions are met.

  • If information from vehicle speed sensors indicates zero
  • If internal combustion engine is idling
  • AIf information from battery sensor indicates that battery can start internal combustion engine again

Internal combustion engine is restarted as soon as driver engages the clutch.

In an automatic-transmission vehicle that uses Start-Stop system, internal combustion engine is stopped if following three conditions are met.

  • If driver depresses brake pedal
  • If information from vehicle speed sensors indicates zero
  • If information from battery sensor indicates that battery can start internal combustion engine again

Internal combustion engine is restarted as soon as driver draws his foot out of brake pedal.

Vehicle stops at red lights or in heavy traffic.
Driver shifts the gear to neutral.
Driver draws his/her foot out of clutch.
Engine stops 10 seconds later.
Signal indicator is on.
Traffic and traffic lights becomes appropriate.
Driver engages the clutch.
Engine restarts.
Signal indicator is off.
Vehicle is ready to move.
