The heating principle of fuel vehicles is different, and the standard is "water heating". The internal combustion engine generates very high temperatures during operation. For example, the combustion flame temperature of gasoline can be as high as 1200°C, while that of diesel is 600°C. If effective heat dissipation is not carried out, the steel of the engine body will easily be melted.
Therefore, there is a water-cooling circulation system through antifreeze coolant.
