标准摘要
[中文适用范围]： 本文件规定了 ISO 3833 中定义的道路车辆推进用内燃机的测试方法。 它适用于评估其性能，特别是以满载时的功率和燃油消耗率曲线来呈现。 发动机转速的函数。 本文件适用于总功率评估。 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。 这些发动机可以使用机械增压器或涡轮增压器进行自然吸气或压力增压。 本文件主要用于发动机制造商和车辆制造商之间的沟通。 如果用于广告目的，额定值将明确说明它们是按照 9.2 的总功率。 [外文原描述]： This document specifies a method for testing internal combustion engines for propulsion of road vehicles as defined in ISO 3833. 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. This document is applicable to gross 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. This document is primarily intended for the communication between the engine manufacturer and the manufacturer of the vehicle. If used for advertising purposes, the ratings will clearly state that they are gross power in accordance with 9.2.
