Effect of the High Temperature Resistant Nano-Coolant on Automotive Engine Operation

摘要

An engine nano-coolant without agglomeration was developed, which was heated to 120 degrees and kept for 15 consecutive days, and has good anti-corrosion, and better thermal conductivity in flow compared with the conventional engine coolant. The results of engine bench scale test, vehicle driving and construction machinery test and exhaust emission test show that the fuel saving rate of the car on the expressway is 5-15%, the fuel consumption of construction machinery decreases by 12.77%, and the temperature of the water tank decreases by 8.17℃ on average in summer without the help of natural wind. In addition, the emission of CO and HC during the driving process also decreases by 7.8-13% and 0-19% respectively, which proves that nano-fluids can significantly increase engine combustion efficiency, prevent engine from overheating at high temperature and reduce exhaust emissions, and will replace the ordinary ethylene glycol-water products as a new type of engine coolant with high thermal conductivity.
