每年秋后天气转冷,农机维修站送修的柴油机(拖拉机)中,因启动困难的要占相当比例。其主要原因是:低温造成润滑油流动性变差,从而启动阻力增加,混合气难以燃烧,使启动变得相对困难。然而,机器本身的技术状态是启动难易的关键。实践证明,柴油机如存在气缸压缩力偏低、启动小孔不畅、供油时间不准等情况时,如果气温较高,这些隐患不足以形成启动障碍,一旦遇到低气温,上述隐患往往造成启动困难。其实,入冬后启动变难的问题不难解决,机手只要用心做到:
Every autumn after the turn of the day cold, diesel engine repair service station (tractor), due to difficult to start to account for a considerable proportion. The main reason is: low temperature caused by the deterioration of the mobility of lubricants, which start resistance increases, the mixture is difficult to burn, so start-up has become relatively difficult. However, the technical status of the machine itself is the key to getting started. Practice has proved that, if there is diesel engine cylinder compression force is low, poor start hole, oil supply time is not allowed, etc., if the temperature is high, these hidden dangers are not enough to form a starting barrier, in the event of a low temperature, the hidden dangers are often caused Difficult to start. In fact, difficult to start after the winter is not difficult to solve the problem, as long as the intention of the driver:
