标准摘要
[中文适用范围]： 本文件规定了一种测试机动车辆发动机的方法。 它适用于评估其性能，特别是呈现满负荷时的功率和燃油消耗率随发动机转速变化的曲线。 它仅适用于净功率评估。 本文件涉及用于推进客车、卡车和其他机动车辆（不包括通常在道路上行驶的摩托车、轻便摩托车和农用拖拉机）的内燃机，并包括以下类别之一： ——往复式内燃机（火花点火或压缩点火式）但不包括自由活塞发动机； ——旋转活塞发动机。 这些发动机可以是自然吸气式或增压式，可以使用机械增压器或涡轮增压器。 [外文原描述]： This document specifies a method for testing engines designed for automotive vehicles. It applies to the evaluation of their performance with a view, in particular to presenting curves of power and specific fuel consumption at full load as a function of engine speed. It applies only to net power assessment. This document concerns internal combustion engines used for propulsion of passenger cars, trucks and other motor vehicles, excluding motorcycles, mopeds and agricultural tractors normally travelling on roads, and included in one of the following categories: — reciprocating internal combustion engines (spark-ignition or compression-ignition) but excluding free piston engines; — rotary piston engines. These engines can be naturally aspirated or pressure-charged, either using a mechanical supercharger or turbocharger.
