Technical Stop Start Technical query

[MattHarris19872016]

Hi what is there under the bonnet for stop start? I'm just curious, is it just like any other engine compartment or is there anything extra there

From memory:

Ecm battery (takes higher charge rate and more starting cycles)

Strengthened starter motor / ring gear

Sensor on gear box to detect neutral and reverse selection. Kill engine in neutral / disable s/s during reversing manoeuvres

Sensor on battery ( measures battery voltage / charge / power retention)

Sensors linked to engine temperature / blower heater / wipers / heated rear screen ( SS won't cut in till car is up to temperature, if windscreen demister or heated screen is on)

Brake servo pressure sensor (low pressure engine restarts)
