According to the characteristics of parts wearing quickly, the driving fault more in automobile breaking-in period, using the method of reducing vehicle load, making the vehicle reduce burden, adapt to work environment, artificially making some countermeasures such as appropriate load shedding, strictly limit, rational use of oil, correct driving, strengthening the maintenance to eliminate troubles in car breaking-in period, which has great practical significance.%根据汽车在走合期零部件磨损快、行驶故障多的特点，利用减少汽车负荷的方法，将汽车减负、减压，适应一定的工作环境，人为地制定适当减载、严格限速、合理用油、正确驾驶、加强维护等排除汽车走合期故障多的对策，具有很大的现实意义。
