Preheating of the engine is often used to facilitate the start of the internal combustion engine in winter, which provides an opportunity not only to increase the comfort of starting, but also to reduce exhaust emissions, increase engine life. That is why the choice of optimal heat storage materials, which on the one hand would have sufficient heat efficiency and on the other hand would satisfy the operational requirements regarding corrosion activity, etc., is an urgent problem. In particular, the barium octohydrate used in our studies is corrosive, although it has a high heat of phase transition heat. The media investigated the media that are ordinary working fluids for heat transfer during heat accumulation: antifreeze, antifreeze, water; heat-accumulating materials – paraffins and octohydrates, and as investigated in relation to corrosion of material steel St3 was considered. The working temperature range was used in the work. It was found that the corrosion rate of 3 mm per year in antifreeze and antifreeze environments requires the choice of anti-corrosion coating or the search for new material that will react.
