汽车上的汽油箱是用薄钢板冲压件焊接,油箱上部装用汽油表传感器、供油开关和加油管。油箱底装有放油螺塞,以排出积水和污物,箱内装有隔板,使油箱加固,在行驶中可减缓汽油的激烈振荡。 油箱使用中要求密封,防止箱内挥发油气逸出,但密封后,随汽油消耗而油面降低时,箱内产生真空,将使汽油吸不出来,而且气温高时,汽油蒸发较多,会使油箱内压力过大,为此, Gas tank on the car is welded with sheet steel stamping parts, the upper part of the fuel tank mounted with gasoline sensor, oil switch and filler pipe. The bottom of the tank is equipped with a drain plug to drain water and dirt. A partition plate is installed in the tank to reinforce the fuel tank, which can reduce the intense oscillation of gasoline while driving. Oil tank requires the use of sealed to prevent volatile oil and gas within the box to escape, but after sealing, with the consumption of gasoline and reduce the oil surface, the vacuum generated inside the box, will not absorb gasoline out, and the high temperature, the gasoline evaporates more So that the pressure inside the fuel tank is too large, therefore,
