内燃机维修中存在着一些技术误区。这些技术误区是在内燃机制造水平低、修理工艺落后、检测手段缺乏的年代逐渐形成的。虽然内燃机的设计制造水平不断提高、不解体检测诊断技术日臻成熟、维修工艺不断更新,可是内燃机维修的一些技术误区却仍然存在,严重影响工程机械的维修质量。摒弃旧观念、旧习惯,推广普及新技术、新工艺,是工程机械维修行业的当务之急。 (1)对内燃机加机油时 There are some technical errors in the internal combustion engine maintenance. These technical misunderstandings are gradually formed in the era of low internal combustion engine manufacturing, repair technology behind, lack of detection means. Although the level of design and manufacture of internal combustion engines continues to improve, the diagnostic technology of non-disintegration testing is becoming more and more mature and the maintenance process is continuously updated. However, some technical errors in the maintenance of internal combustion engines still exist, seriously affecting the quality of maintenance of construction machinery. Abandoning the old ideas, old habits, popularization of new technologies, new technology, construction machinery repair industry is the top priority.
