Which cars are made in China use engineering plastic fuel tanks?
From the perspective of energy saving and environmental protection, the weight of the plastic tank generally only metal tank 1/2, can directly reduce the vehicle weight, thereby reducing the overall energy consumption, in addition, the reuse rate of plastic fuel tank can reach more than 90%.But this does not mean that all cars must use the plastic tank, according to the specific configuration and technical standard of each car, such as the large passenger cars and trucks almost all use the tin tank, because the tank of the car itself, the space occupied by the weight and did not have much effect.
The design of plastic fuel tank has better degree of freedom, with the continuous progress of the automobile design process, at the bottom of the car to the tank space more and more small, the space for various special-shaped metal forging tank in terms of cost and manufacturability, produce insurmountable obstacles, and the plastic fuel tank may be in the design of other parts of the car later, with good plastic molding performance, make full use of the remaining space given, making possible the profiled tank;
1, the metal tank is prone to electrical sparks, and the plastic tank does not exist this problem;2, the tank is generally metal welding, welding seam, easy in impact fracture and plastic tank is one-time molding, with impact resistance, anti cracking performance better, after a serious car crash after the plastic oil box in addition to the occurrence of deformation, does not occur cracking leakage phenomenon, greatly reduce the possibility of fire accident;3, plastic fuel tank also has better protection against external environmental corrosion and oil erosion resistance, long-term use can still maintain good performance;
From the iron tank to the plastic fuel tank is a trend. At present, the use of plastic fuel tanks in domestic cars has become very common, especially the car, the utilization rate has reached 70%, which is fairly small, in foreign countries, the proportion of up to 90%.
Basically, engineering plastics, metal tank, that is, iron tank, now in addition to the black heart car dealers are rarely used
