Heating oil tank design principles; 1, the use of the heat generated by the engine when the car running, an additional set of thermal cycling system between the engine, fuel tank, water tank. . 3, water heater installed in the inside of the tank, the use of the heat generated by the engine to the main tank heating. 4, the main tank pipeline and pay the fuel tank tubing and engine oil through the oil passage switching valve connected with the payment of the fuel tank in the car to start, switching valve travel 5-8 km after moving to cut the oil line to the main fuel tank. 5, the main tank 0 # oil to pay tank -35 # oil. 6, the main tank oil line heater pipeline parallel, and the oil line pipeline and heating pipelines jacket pipe insulation to prevent the oil line Freezing cold season. 7, the main fuel tank oil standard display glass tube can be outside the box and pay the oil tank marked with driving indoor dial connection. 8, thermal cycling system with valve control summer transport the heating valve to close it. (B) heating the fuel tank to the energy saving functions and features to change the cold regions winter driving can only use the oil of the status quo of -35 # 0 # oil by heating alternative -35 # oil. 2, heavy duty truck 40T one hundred kilometers an example: -35 # oil 100 km fuel consumption of 40 liters; 0 # oil 100 km fuel consumption of 35 liters, one hundred kilometers fuel economy of 5 liters. -35 # Oil # oil 1 dollar per liter, a difference of one hundred kilometers to 40 yuan. One hundred km fuel economy of 5 liters * 5.3 = 26.5 yuan +40 = the 66.5 yuan cycling winter transport a total mileage of 30,000 km, calculated down transportation costs can knot about 30,000 ÷ 100 * 66.5 = 19,950 per 1500 liters of fuel economy to reduce the car broke down due to the oil line Freezing winter transportation guide system, the impact of road transport, traffic congestion. 4, to overcome the insecurity, water heating electric heating and exhaust pipe to the heating-generation safer, more convenient. 5, the operation is simple, a safety factor of 100%. 6, the use of engine heat, and the formation of the water cycle heating process, the protective effects of the fall in temperature of the engine. Prolong engine life. 7, the water temperature balance does not appear high oil temperature generated by natural phenomena. (C) emission reduction effect of fuel after preheating adequate combustion and reduce exhaust emissions. 2, the amount of fuel in the unit mileage reduction while reducing exhaust emissions. Summarized in 14 words: energy saving effect; increase production and income, increase efficiency
