问:什么是耗油量?什么是耗油率? 答:耗油量就是柴油机在单位时间内消耗的燃油量。常用G表示。耗油率就是每千瓦功率,每小时内燃油的消耗量。常用g_e表示。耗油率是评定柴油机经济性能的主要指标。它和柴油机构造、工作情况、技术保养以及调整工作的质量等有关。当柴油机在低负荷工作时,虽然耗油量降低,但耗油率却上升,这是因为有效功率降低了。若有效功率低到接近零时,柴油机还要克服摩擦阻力,才能继续运转,而耗油量却总不能降低到零。因此在柴油机的工作过程中,为了减少燃油消耗,应尽可能使柴油机在满负荷的情况下工作。
Q: What is the fuel consumption? What is the fuel consumption? A: The fuel consumption is the amount of fuel the diesel engine consumes in unit time. Commonly used G said. Fuel consumption is the amount of fuel consumed per kilowatt hour and hour. Commonly used g_e said. Fuel consumption is to assess the economic performance of diesel engines the main indicators. It and diesel engine structure, work conditions, technical maintenance and adjustment of the quality of the work and so on. While diesel engines operate at low loads, the fuel consumption rate increases although the fuel consumption is reduced because the effective power is reduced. If the effective power is low to near zero, the diesel engine must overcome the frictional resistance to continue to operate, but the fuel consumption can not always be reduced to zero. Therefore, in the process of diesel engine, in order to reduce fuel consumption, diesel engines should be as full as possible under the conditions of work.
