Introduction

GB/T 8190 aims to rationally formulate test procedures for non-road engines and simplify relevant regulations on gas and particulate matter emission control.

The drafting of engine technical specifications and engine certification should be carried out in an economical and efficient manner.

To achieve the above objectives, GB/T 8190 adopts three basic principles.

---First principle. Classify applications according to the similar operating characteristics of the engines in order to minimize the number of test cycles, while ensuring these...

After.2010, ISO/TC70/SC8 initiated the integration of ISO 8178.By.2017, the integration of ISO 8178-1 was completed.

In.2006, ISO 8178-4:2007 and ISO 8178-11:2006 were integrated, resulting in the publication of ISO 8178-1:2017 and ISO 8178-4:2017.

(Revised again in 2020 to ISO 8178-1:2020 and ISO 8178-4:2020); In.2019, ISO 8178-3:1994 and ISO 8178-ISO 8178-9:2012 and ISO 8178-10:2002 were integrated, resulting in the release of ISO 8178-3:2019 and ISO 8178-9:2019.Thus, ISO 8178 was transformed from its original form...

The field testing procedures and calculation methods specified in this document apply to situations where a test bench cannot be used or where actual emissions data for in-use engines are required.

In this context, due to the diversity of non-road engine applications, assessing emissions from non-road engines is more important than assessing emissions from road engines.

Due to the variability and uncontrollability of field trials, the data obtained in these situations may differ from previously or future laboratory data.

The on-site data are not entirely consistent.
