Introduction

Measuring system depends on the type of test cycle, the steady-state or transient, and the kind of measured pollutants. Under steady-state cycling conditions, exhaust gas Total emissions can be easily measured in accordance with the original engine exhaust concentration and exhaust flow, or diluted depending on the concentration and total diluted exhaust gas flow System CVS (Constant Volume Sampling) flow calculated. Both have a similar system is described in GB/T 8190.1 Lane. For particulate matter , The only part of the exhaust gas may dilution using a full flow dilution system or the partial flow dilution system.

In this part of the transient cycle conditions GB/T 8190 regulations, the more difficult real-time determination of the exhaust gas flow. Thus, since the whole Flow dilution system does not require the determination of the total exhaust flow, CVS principle has been applied for many years. The total diluted exhaust gas, so that the total flow Volume (dilution air and exhaust gas flow and) maintain a constant exhaust gas and particulate matter would have to be measured in diluted state. This system Partial flow dilution system is much higher demand for space and cost than under steady state cycling conditions. On the other hand, if you use a complex control system Systems and calculation methods, the raw exhaust gas measurement and partial flow dilution system can also be used for transient conditions.

For most non-road use and heavy-duty engines, CVS system seem large and wasteful. Thus, ISO 16183 by ISO/T C22/SC5 improvements, and a detailed description of the raw exhaust gas measured under transient test conditions of heavy-duty engines in the standard method and partial flow dilution system. Since many non-road engines on engine size, displacement and heavy-duty engines with similar power, ISO 16183 content can also be used for non-road engines.

In this section, the full flow dilution and partial-flow dilution/exhaust original method is considered to be equal, so here are two methods include.

1 Scope

This section GB/T 8190 specifies the test stand measurement and evaluation side reciprocating internal combustion engine under transient operating conditions of gaseous and particulate emissions Method to determine the emission values for each pollutant emissions.

Specific transient test cycle covered in this section applies to the output power from 37kW ~ 560kW of compression-ignition engines, mainly for Except for road vehicles designed engines. This section applies to GB/T 8190.4-road vehicles as defined in 8.3.1.3 and diesel Driver non-road engines of industrial equipment, including the construction machine including a variety of engine applications, these applications include. wheel loaders Machines, bulldozers, crawler tractors, crawler loaders, truck-type loaders, off-road trucks, hydraulic excavators, agricultural equipment, self-propelled agricultural Vehicles (including tractors), forestry machinery, forklifts, road maintenance equipment and mobile cranes.

Since a discharge measured value requires a complex set of individual measurements, rather than just to provide a single measurement, so below Many procedures for laboratory methods are described in detail in the narrative, so that the test results depends not only on the engine and test methods, but also on the course of measurement.
