汽车在高原条件下工作时,由于大气压力的降低使发动机气缸内的充气量,及功率下降,其动力性和燃料经济性亦显著下降。高度每增1000米,发动机功率下降11～13％,燃油比耗率增加10～11％,动力因数下降11～13％,而最高车速降低10％。在海拔4000米的高原,吉尔—130型汽车的最高车速只能达到55公里/小时,而不是85公里/小时。可是,加速时间和加速里程却增加了二倍。结果汽车生产率下降16～22％。
When the car is working in the plateau, the power and fuel economy of the engine cylinder also decreases significantly due to the reduction of the atmospheric pressure and the decrease of the air volume in the engine cylinder and the power. For every 1000 meters of height, the engine power drops 11-13%, the fuel consumption rate increases 10-11%, the power factor drops 11-13%, and the maximum speed decreases 10%. At an altitude of 4,000 meters above sea level, Jill-130 cars can only reach a maximum speed of 55 km / h instead of 85 km / h. However, acceleration time and acceleration mileage have tripled. The result is a 16-22% drop in car productivity.
