我国农用柴油机的保有量已达1.2亿马力以上,平均每马力农用柴油机供应的柴油量已从1970年的112公斤减少到1981年的50公斤。如果每马力小时的实际油耗为200～250克,则1981年的供应量只能满足柴油机工作200～250小时的需要。因此,必须千方百计节约用油,并且在有条件的地方开发代用燃料。一、农用柴油机的油耗水平近两年来,节约能源已经成为重要的国家政策,科研机构、制造厂以及管理部门对降低柴油机的油耗都非常重视。国产柴油机的油耗指标已有改善,特别是标定工况的油耗有了显著降低(见下表),国产单缸
The amount of agricultural diesel engines in our country has reached more than 120 million horsepower. On average, the amount of diesel fuel supplied per horsepower agricultural diesel engine has dropped from 112 kilograms in 1970 to 50 kilograms in 1981. If the actual fuel consumption per horsepower hour is 200 to 250 grams, the supply in 1981 can only meet the diesel engine needs of 200 to 250 hours. Therefore, every effort must be made to conserve oil and to develop alternative fuels wherever possible. First, the level of fuel consumption of agricultural diesel engines In the past two years, energy conservation has become an important national policy, scientific research institutions, manufacturing plants and management departments to reduce the fuel consumption of diesel engines attach great importance. Domestic diesel engine fuel consumption indicators have been improved, especially in the calibration conditions of fuel consumption has been significantly reduced (see table below), domestic single cylinder
