Preheating Relays

The engine can be started when a warning light gives the signal that the correct engine temperature has been reached.

For the applied glow or flame plugs WEHRLE manufactures the appropriate control devices.

The duration of the preheating period depends on the engine’s temperature. The start readiness of the engine is signalled by a preglow lamp. Versions with post-heating to reduce the cold start emissions and immediate start devices are available.
