(一)试验目的汽油发动机汽车在夏季或高原地区工作时,常因供油系内汽油蒸发而产生气泡,引起供油不畅发生故障,称之为气阻。由于产生气阻,将迫使汽车停驶,影响汽车的正常运转。因此,抗气阻能力是评价汽车对炎热地区或高原地区工作适应性的重要指标之一。抗气阻能力试验的目的,就是要了解和评定现生产或新设计汽车的抗气阻能力,以及研究改善抗气阻能力的措施和效果。 (A) The purpose of the test Gasoline engine cars in the summer or high altitude work, often due to gasoline vaporization within the fuel supply system and produce bubbles, causing poor oil failure, called air resistance. As a result of air resistance, will force the car to stop, affecting the normal operation of the car. Therefore, the resistance to air resistance is to evaluate the car on the hot or plateau work adaptation one of the important indicators. The purpose of the anti-air-resistance test is to understand and assess the anti-air-resistance capability of a car that is being manufactured or newly designed, as well as to study measures and effects of improving its anti-air-resistance capability.
