Introduction
Compared with on-road engines, off-road engines have a very wide power range and structure, and can be used in many different
use:
GB/T 8190 aims to reasonably formulate the test procedures for non-road engines, so as to play a role in the regulations for the control of gas and particulate matter emissions:
Drafting, engine specification preparation and engine certification are simplified and cost-effective:
To achieve the above objectives, this document adopts three basic principles:
First principle: Divide the application according to the similar operating characteristics of the engine, so as to reduce the number of test cycles to a minimum, but ensure that these tests
The cycle can represent the actual operating conditions of the engine:
The second principle: the emission measurement results are expressed according to the effective power stipulated in GB/T 8190:1, which can ensure that when the engine usage changes
It is not necessary to repeat the experiment when the time changes:
The third principle: introduce the concept of engine family: In this family, engines with similar emission characteristics and similar construction can use this
represented by the highest-emitting engine in the family:

Transient test cycle
1 Scope
This document specifies the test cycle, test procedure and evaluation of gaseous and particulate emissions from reciprocating internal combustion engines coupled to a dynamometer: exist
Under certain limited conditions, this document can also be used for field measurements: Tests are performed under steady state and transient conditions using test cycles representative of the intended use
conduct:
This document applies to mobile, transport and stationary reciprocating internal combustion engines, such as earth-moving machinery, generating sets and other non-road engines
Motives, but excluding road engines for the transport of passengers and goods: For other additional requirements (such as occupational health and safety regulations, power plant
Regulations) engines for mechanical equipment, supplemented with additional test conditions and special evaluation methods:
