Commission Delegated Regulation (EU) No 134/2014Show full title

4. Requirements

4.1. General requirements

The design, construction and mounting of the replacement pollution-control device type shall be such that:

4.1.1.

the vehicle complies with the requirements of this Regulation under normal conditions of use, and in particular regardless of any vibrations to which it may be subjected;

4.1.2.

the replacement pollution-control device displays reasonable resistance to the corrosion phenomena to which it is exposed, with due regard to the normal conditions of use of the vehicle;

4.1.3.

the ground clearance available with the original equipment pollution-control device type and the angle at which the vehicle can lean over are not reduced;

4.1.4.

the surface of the device does not reach unduly high temperatures;

4.1.5.

the outline of the device has no projections or sharp edges;

4.1.6.

shock absorbers and suspension have adequate clearance;

4.1.7.

adequate safety clearance is provided for pipes;

4.1.8.

the replacement pollution-control device is impact-resistant in a way that is compatible with clearly-defined maintenance and installation requirements;

4.1.9.

if the original equipment pollution-control includes thermal protection, the replacement pollution-control device shall include equivalent protection;

4.1.10.

if (an) oxygen probe(s) and other sensors or actuators are originally installed on the exhaust line, the replacement pollution-control device type shall be installed at exactly the same position as the original equipment pollution-control device and the position on the exhaust line of the oxygen probe(s) and other sensors or actuators shall not be modified.

4.2. Requirements regarding emissions

4.2.1. The vehicle referred to in point 3.4.1, equipped with a replacement pollution-control device of the type for which type-approval is requested, shall undergo the tests laid down in Annexes II and VI (depending on the type-approval of the vehicle)(1).

4.2.1.1.

Evaluation of pollutant emissions from vehicles equipped with replacement pollution-control devices

Requirements regarding tailpipe or evaporative emissions are deemed to be complied with if the test vehicle equipped with the replacement pollutant-control device complies with the limit values in Annex VI to Regulation (EU) No 168/2013 (according to the type-approval of the vehicle)(1).

4.2.1.2.

Where the type-approval application is for different types of vehicles from the same manufacturer, the type I test may be limited to as few as two vehicles selected after agreement with the technical service to the satisfaction of the approval authority, provided that the different types of vehicle are fitted with the same type of original equipment pollution-control device.

4.2.2. Requirements regarding permissible sound level

The vehicles referred to in point 3.4.1, equipped with a replacement pollution-control device type that could allow worse noise emissions than the type for which type-approval is requested, shall satisfy the requirements of Annex IX (according to the type-approval of the vehicle)(1). The test result for the vehicle in motion and for the stationary test shall be mentioned in the test report.

4.3. Testing of the propulsion performance of the vehicle

4.3.1. The replacement pollution-control device type shall be such as to ensure that the propulsion performance of the vehicle is comparable with that achieved with the original equipment pollution-control device type.

4.3.2. The propulsion performance of the vehicle equipped with the replacement pollution-control device shall be compared with that of an original equipment pollution-control device, also in new condition, fitted in turn to the vehicle referred to in point 3.4.1.

4.3.3. This test is carried out according to the applicable procedure set out in Annex X. The maximum net power and torque as well as the maximum attainable vehicle speed, if applicable, measured with the replacement pollution-control device, shall not deviate by more than + 5 % from those measured under the same conditions with the type-approved original equipment pollution-control device type.
