In the Opel Astra j 1.4 directly in the cooling water thermostat is a heating directly in the opening element. It was explained to me so if then gives up the thermostat so that the warmer cooling water in the interior would mix with the cooling water in the cooler and thus the engine should burn even colder. That would also save fuel. I now have some doubts about this explanation. To one mad time discrepancy until the cooling water actually changes its time, this the The cooling water temperature is adjusted, then it would take again until the cooling water in the small circuit is warmer again and if it is ready to drive again. If it runs stupidly I would drive with it always in an unfavourable temperature range. In addition, the combustion temperature of air temperature, fuel temperature and Lamb Since determined, everything else yes yes less influence, I think even if on average the metal of the engine plus minus a few degrees has no influence at all on the combustion temperature and consumption values. And let’s assume that I have a performance zenairo like with hangers up the mountain and I am anyway above the temperature value makes no sense this solution at all. In my whole circle of acquaintances I only harvest headshake. Is this a purely Opel specific construct or have such a This reads like marketing speech, how in the TV sales channel this one tool replaces an entire tool box. But it doesn’t make any sense in reality, If I would calculate this or simulate it I would be sure I wouldn’t have a chance to work here Is there anyone here who knows more about this?
