众所通知,拖拉机及联合收割机用柴油机台架试验标准[1]规定的标准状况换算不能应用到带校正的和额定的扭矩储备系数上。而扭矩储备系数则是重要的评价参数,其数值由技术条件规定,并在定期、鉴定和予备试验中加以检验。正如试验所指出的,该系数换算取决于环境大气压力、温度和湿度以及燃油温度。但实际上在苏联及其它国家的标准和技术文件中对其换算并没有规定。在本文中给出了进行换算的公式和诺谟图,系按苏联生产的拖拉机
It has been noticed that the conversion of the standard conditions specified in the test bench for tractors and combine harvesters [1] can not be applied to calibrated and rated torque reserves. The torque reserve factor, on the other hand, is an important evaluation parameter whose value is defined by the technical conditions and tested in regular, certified and preliminary tests. As the experiment points out, this factor conversion depends on the ambient atmospheric pressure, temperature and humidity, and fuel temperature. However, there are virtually no provisions on the conversion in the standards and technical documents of the Soviet Union and other countries. In this paper, the conversion formula and nomogram are given, according to the Soviet Union produced tractors
