Doba žhavenia pred a po naštartovaní je závislá od viacerých činiteľov. Tu je príklad pre 307ku:
The preheating time varies depending on engine temperature.
Engine coolant temperature Pre-heating (pred žhavenie) duration
- 30 °C 16 seconds
- 10 °C 5 seconds
0 °C 0,5 seconds
10 °C 0,25 seconds
18 °C 0 seconds
40 °C 0 seconds
Post-heating (dožhavenie) allows the operation of the heater plugs to be prolonged following the starting phase.
Postheating is used to reduce pollutant emissions during the first few minutes after starting.
Engine coolant temperature Post-heating duration
- 30 °C 3 minutes
- 10 °C 3 minutes
0 °C 1 minute
10 °C 1 minute
18 °C 30 seconds
40 °C 0 seconds
Parameters which can interrupt the postheating :
Engine coolant temperature lower than 20°C.
Injected fuel flow exceeding 35 mm3.
Engine speed greater than 2000 rpm.
