"Termocoppia" o sensore di temperatura
Inviato: 08/05/2017, 5:38
Cotta la guarnizione della testa stavo pensando di mettere una termocoppia, così la chiamano, ma non so se sia meglio forare la placca che tappa l'EGR, come ho visto si fa con certi kit australiani o sudafricani (http://www.thermoguard.com.au/instal.html) che però hanno un prezzo improponibile vista la semplicità dell'intervento, o inventarsi qualcosa per installarla all'altezza della vite di spurgo della linea di raffreddamento.
Cosa è meglio misurare in definitiva, la temperatura dei gas di scarico o quella dell'acqua?
Cito una discussione che vi linko:
"The 'normal' (and easiest) place is through the EGR blanking plate. But I wanted mine closer to a valve so drilled and tapped the manifold by no. 1 cylinder. Being cast iron the manifold is easy to work. Used lots of grease on the drill and tap to stop swarf falling into the donk. My 'meter' is actually a 12v digital furnace controller - it is programmed to switch off at a certain temp (I use 725°C) and this switch is used to power a buzzer just in case I don't notice the temp being high.
Why is the temp high you may ask? Because I have 'tweaked' the injector pump.
I let the temp stabilise to 200°C before switching off. This can be instantaneous if stopped after going downhill or can take a long time to come down as when pulling off a motorway to refuel (I refuel with the engine running). What I can say is that my turbo is still perfect at 300k kms (187k miles). So that seems to help - along with regular oil changes." (https://forums.lr4x4.com/topic/72970-eg ... n-300-tdi/)
