Start/Stop Starter Motor

Innovative = kinder to the climate

Our new Start/Stop System turns car driving into pure pleasure. Because it helps you to protect the environment, to save fuel and at the same time to revel in pure driving comfort. When you stop – at a red traffic light for instance – this function switches the engine off automatically. As soon as you depress the accelerator pedal, the motor starts up again immediately almost without your noticing. This is thanks not only to electronic control but also to our novel Start/Stop Starter Motor, which starts the internal-combustion engine particularly quickly and quietly.

1. Engine off – and a warm start

When idling, an internal combustion engine is using fuel
unnecessarily, as documented in the vehicle’s idling fuel-
consumption figure. So what would be more sensible than
to switch the engine off? The energy required to re-start a
modern gasoline engine is so minimal that even turning
the engine off for as little as 0.7 sec is worthwhile (2.0-liter
gasoline engine)


Example:

A 2.0-liter gasoline engine with an idling consumption
of 1 liter per hour would consume 0.008 liter of fuel if left
idling for 30 seconds. Starting the engine only requires
0.0003 liter of fuel, a proportion of only 4%

  • 96% of CO2 emissions and fuel consumption saved
    by turning off the engine
  • Today’s traffic situation leads to a considerable propor-
    tion of stoppage times (traffic lights, stop-and-go). Let us
    assume that a daily trip includes 12 stops of 30 seconds.
    This would enable you to save 15% of your fuel.

2. Measuring cycle

The ECE 15 measuring cycle (city portion of the NEDC)
comprises a journey of 7 kilometers with 12 stops of 15
seconds each. With our Start/Stop Starter Motor you can
reduce CO2 emissions and fuel consumption by up to 7%.


3. Stops

In fact – a fact which all of us experience day in, day out –
stops are considerably longer, particularly in city traffic.
Even with an average stopping time of 30 seconds per
stop, these savings are doubled to approximately 15%.
