在机械施工中,节约燃油和润滑油,不仅能降低工程成本,而且对延长建筑机械寿命也有积极意义。世界节能委员会研究表明:工业发达国家能源利用率为50%多,我国只有30%左右。据1981年统计,我国有200多万台汽车,年耗汽、柴油约一千万吨,与国外七十年代产品相比,每100km油耗高15～20%,可见我国的节能潜力很大。目前施工现场,不少建筑机械油耗率超过定额,其中多数是缺乏科学管理所致。
In mechanical construction, saving fuel and lubricants, not only can reduce the cost of construction, but also to extend the life of construction machinery is also of positive significance. World Energy Conservation Committee studies have shown that: industrialized countries, energy efficiency of more than 50%, China is only about 30%. According to the statistics of 1981, there were over 2 million vehicles in our country, consuming about 10 million tons of diesel and about 10 million tons of diesel fuel per year. Compared with the products from the 1970s, the fuel consumption per 100 km was 15 to 20% higher. This shows that our country has great potential for energy saving. The current construction site, many construction machinery fuel consumption rate of more than a fixed amount, most of which is the lack of scientific management.
