履带式推土机要求所配套的发动机不但要有足够的功率,而且自身散热性能要好。否则,就会发生在较高气温下工作时,作业负荷不太大也会出现温度过高的现象。这直接影响了推土机的正常作业。本文通过国内外冷却系统的对比,提出一些改进措施。 Crawler-type bulldozers require that the supporting engine not only has sufficient power, but also has better heat dissipation performance. Otherwise, it will happen that when the work is performed at a higher temperature, the work load will not be too large and the temperature will be too high. This directly affected the normal operation of the bulldozer. This article puts forward some improvement measures through comparison of cooling systems at home and abroad.
