Introduction

This document is a measurement procedure for determining the emission levels of gaseous and particulate pollutants from non-vehicle reciprocating internal combustion engines: Its purpose is to provide the emission characteristics of the engine can be used to indicate the performance of the engine in various applications and on different fuels by using appropriate weighting factors and test cycles:

lower emission levels: Emissions results are given in grams per kilowatt-hour and represent the emission rate per unit of work performed:

Many of the procedures described in this document are elaborations of laboratory methods, since the determination of emission values requires a complex set of individual Instead of getting a single measurement: Therefore, the results obtained depend both on the engine and the test method and on the measurement process:

Due to the diversity of off-road uses, assessing emissions from off-road engines is more complex than the same task for on-road engines: For example, Tao Road uses primarily consist of moving loads from one point to another on paved roads: Paved roads, maximum acceptable road loads and maximum allowable Limitations on many fuel grades narrow the range of road vehicle and engine sizes: Engines for off-road vehicles come in a wider range of sizes, including the engine that powers the device: Many engines are too large to use road-acceptable test equipment and methods: in unavailable in the case of a dynamometer, the test may be carried out on site or under appropriate conditions:

In limited circumstances, engines that need to be tested on site according to GB/T 8190.2 can be tested on the test bench test: But this can only be done with the consent of the parties involved: It should be recognized that data obtained under these circumstances may not be the file is not completely consistent with previous or future data:

Additional test conditions and special evaluation method:

If the test bench cannot be used or the actual emission information generated by the engine in use is required, the on-site test specified in GB/T 8190.2 can be used Procedures and calculation methods:
