Dependence of petrol’s loss because of «big breath» from the remaining fuel The initial volume of petrol in the tank with 60 liter, l Petrol’s loss in the tank, ml 10 о С 30 о С 1.2 14.1 29.9 4.7 19.3 39.6 7.5 26.1 53.8 15.0 34.9 80.7 Developed approach based on reducing of petrol vapors losses in the tank: in the fuel and steam distribution system the intermediate tank inserted with diesel fuel. The effect of fuel economy is higher, the smaller the ratio V p /V i.t. where V p - the volume of incoming petrol, and V i.t. is the volume of GS «intermediate» tank (Table 3).

Initial selected construction material: polyurethane is 61 electrified and flammable. Polyethylene terephthalate was deprived of these disadvantages. Moreover, it is not impregnated by the petroleum product. The next task was choosing the form of a pontoon float. Hollow spheres were characterized by density of 55 kg / m 3 , which is 18-20 times lower than the density of water and up to 18 times of fuel. Floats provided 85% inhibition of fuel evaporation while they are afloat. The pressure of the saturated vapor and losses off the evaporation was measured (Table. 4). Download 1.67 Mb.
