Overview

A draft regulation [24], containing amendments to the new Euro 6 implementing regulation, 2017/1151, was published in March 2018. Amongst the proposed amendments are updated provisions on the implementation of the WLTP test cycles, the RDE 4th package, a new procedure for the assessment of in-service conformity (ISC) and requirements for on-board monitoring of fuel and/or electric energy consumption. The draft is currently being examined by the European Parliament and Council [25]; the regulation is expected to apply from 1 January 2019.

Durability of Emissions Control Devices

The required durability of pollution control devices has been extended to 160,000 km for Euro 5 and 6, and manufacturers have three options for the demonstration of that durability [2]:

1. A whole vehicle durability test with ageing carried out on a test track, on road or on a chassis dynamometer.

2. A bench ageing durability test.

3. The manufacturer may choose to apply assigned deterioration factors as shown in the following table.

Table 6: Assigned Deterioration Factors
Engine Category CO THC NMHC NOx HC + NOx PM PN
Positive Ignition 1.5 1.3 1.3 1.6   1.0 1.0
Compression Ignition (Euro 5) 1.5     1.1 1.1 1.0 1.0
Compression Ignition (Euro 6) (1)              

Note:
1. Euro 6 deterioration factors to be determined.
