一、前言在内燃机测试中,为了比较在不同大气状况下测得的功率和燃油消耗率的大小,以及衡量它们与设计指标的差异,往往需要对实测结果进行换算。在高原地区,更为必要。换算时通常采用《内燃机功率及燃油消耗率换算方法》中提供的公式(公式见后),由于式中p、t、φ、P_w、η_(m0)等都是变量,在用公式计算时,若缺少现代运算工具,确会使人感到麻烦。尽管可以事先准备一些数表协助,但仍要多次查表及插值法计算。本文介绍一种图算法:即在一张图上经过几次连续图算,可以同时得到功率和燃油消耗 I. INTRODUCTION In the testing of internal combustion engines, it is often necessary to convert the measured results in order to compare the measured power and fuel consumption rates under different atmospheric conditions and to measure their differences from design specifications. In the plateau area, more necessary. Conversion is usually used in the “internal combustion engine power and fuel consumption rate conversion method” provided in the formula (formula see below), because the type of p, t, φ, P_w, η_ (m0) and so are variables in the formula, The lack of modern computing tools really makes people feel trouble. Although it is possible to prepare some digital assistants in advance, there are still many lookups and interpolation calculations. This article describes a graph algorithm: that is, after several successive graphs on a graph, you can get power and fuel consumption
