Do you have a reference for the car engine thing? I did a quick search and couldn't find anything yet. Sounds really interesting, I'd like to read more.

- kw71 8y agoFord has been doing this for decades (I think I saw it mentioned in the docs for EEC IV.) It turns off fuel for a cylinder here and there intending to pump heat out of the engine (a cylinder with no fuel is an air pump.) It doesn't really let you operate with no coolant. Might get you farther before you die if you push it.
- derekp7 8y agoYou are correct, that the manual doesn't specifically say it can operate without coolant (now that I re-read it). What it does is active fail safe mode, then will shut the engine off once the temperature goes above another (higher) threshold. So I guess if coolant is completely gone (instead of just low), you may be able to drive for a few minutes then be shut down for a while before driving again (the main purpose is to give you enough time to find a safe spot to stop).
- derekp7 8y agoHere is the owners manual for my car: http://www.fordservicecontent.com/Ford_Content/Catalog/owner_information/2017-Fusion-Hybrid-Owner-Manual-version-3_OM_EN-US_02_2017.pdf http://www.fordservicecontent.com/Ford_Content/Catalog/owner... On page 259, under the heading "Fail-Safe Cooling". If the engine reaches a preset over-temperature condition, the engine automatically switches to alternating cylinder operation. Each disabled cylinder acts as an air pump and cools the engine. When this occurs, your vehicle still operates, however: • Engine power is limited. • The air conditioning system turns off. Continued operation increases the engine temperature, causing the engine to completely shut down. Your steering and braking effort increases in this situation.
