Regarding the cold starts, I was just wondering.
Given the fact that the usual comute involves leaving home in the morning and getting back in the evening, wouldn`t keeping the engine warm for 12-14 hours be a fix for most of the start-ups ?
I was thinking that maybe adding thermal mass to the engine and a bit of thermal insulation on the top and sides of the engine bay would do the trick.
I know that there are some old threads ( about winterizing the car ), but I haven`t found any input on adding thermal mass to the engine.
I tried this ( without logging data ) by using about 0.3 kg of wax. I just melted the wax, poured it into some plastic freezer batteries and placed them on top of the engine.
How could this idea be refined ? I think that all that waste heat from the engine can be stored just long enough to have a slightly warm engine the next day.
