![]() ![]() The lever is actuated by a ‘wax stat’ type device that is supplied with 12V when the engine is running, as it warms up the wax expands and moves the lever from the advanced timing position back to the normal running position. This is because the actual fuel burn when injected is slower in a cold engine so injecting it a little earlier allows more time for a complete burn. On the diesel injection pump there is a lever that when actuated advances the diesel injection timing a few degrees. The 8140.43 2.8L Diesel engine used in various Fiat Ducato, Peugeot Boxer, Citroen Relay and other vans and MotorHomes uses a fairly unusual cold start system, here we’ll look at how it works so if you need to do any troubleshooting, you know where to start!įirstly, there are two separate cold start systems, one that advances the diesel injector timing whenever the engine is started from cold, and another ‘Flame Start’ device that operates whenever the ambient temperature is around freezing or lower.
