汽车上使用的汽油机和柴油机按国家标准(GB1174-74)规定,在气温分别不低于-5°和0℃的条件下,应能顺利起动。一般国产汽车均能满足上述要求。但是在冬季进行野外作业和执行某些特殊任务的车辆,由于发动机的预热工作受到客观条件的限制,往往需要冷车起动,因此对这些车辆必须要解决发动机的冷起动问题。在使用过程中,汽车发动机冷起动的主要措施是:保持蓄电池和起动机的技术状况完好;合理选用润滑油;使用高挥发性的燃料做起动燃料。这三个方面相互配合,就可以大大
Gasoline engines and diesel engines used in automobiles shall be in accordance with the national standard (GB1174-74) and shall be able to start smoothly under the conditions of temperatures not lower than -5 ° and 0 ° C respectively. General domestic cars can meet the above requirements. However, vehicles that perform field work in winter and perform certain special tasks often require cold start because engine warm-up is limited by objective conditions. Therefore, these vehicles must solve the problem of cold start of the engine. In the process of using, the main measures of cold start of the automobile engine are: keep the technical condition of the battery and the starter intact; reasonably select the lubricating oil; and use the fuel with high volatility to start the fuel. These three aspects cooperate with each other, you can greatly
