Steady-State and Transient Test Cycles

The BS ISO 8178-4:2020 standard distinguishes itself by providing detailed instructions for both steady-state and transient test cycles. Understanding these two types of test cycles is crucial for accurately assessing engine emissions:

Steady-State Test Cycles

Steady-state test cycles involve measuring emissions at constant engine speeds and loads. This type of testing is essential for evaluating the performance of engines under stable operating conditions. The standard provides specific guidelines on how to conduct these tests, ensuring that the results are both accurate and repeatable.

Transient Test Cycles

Transient test cycles, on the other hand, involve measuring emissions during changes in engine speed and load. This type of testing is critical for understanding how engines perform under real-world driving conditions, where speeds and loads can vary significantly. The BS ISO 8178-4:2020 standard offers detailed procedures for conducting transient tests, helping professionals capture a more comprehensive picture of engine emissions.

BS ISO 8178-4:2020

• 13.040.50 Transport exhaust emissions
• 27.020 Internal combustion engines

This document specifies the test cycles, the test procedures and the evaluation of gaseous and particulate exhaust emissions from reciprocating internal combustion (RIC) engines coupled to a dynamometer. With certain restrictions, this document can also be used for measurements at site. The tests are carried out under steady-state and transient operation using test cycles which are representative of given applications.

This document is applicable to RIC engines for mobile, transportable and stationary use, excluding engines for on-road transport of passengers and goods. It can be applied to engines for non-road use, e.g. for earth-moving machines, generating sets and for other applications. For engines used in machinery covered by additional requirements (e.g. occupational health and safety regulations, regulations for power plants), additional test conditions and special evaluation methods can apply.
