Traduction de «automobile à moteur diesel » (Français → Anglais) :

However, besides the fact that the determination of whether cars with petrol motors and cars with diesel motors form one single product is not subject to the present interim review, the above comparison was considered inappropriate because focused on the wrong parameter (the motor).

So any car can take low-sulphur fuel and it has a positive effect, especially with older types of diesel engines.

Road vehicles are increasingly reliant upon catalytic after-treatment devices to attain the emissions limits mandated in Council Directive 70/220/EEC relating to measures to be taken against air pollution by gases from positive-ignition engines of motor vehicles and Council Directive 88/77/EEC relating to the measures to be taken against the emission of gaseous pollutants from diesel engines for use in vehicles.

(12) Whereas new type-approval test cycles for gaseous and particulate emissions and smoke opacity are introduced that will allow a more representative evaluation of the emissions performance of diesel engines over test conditions that more closely resemble those encountered by vehicles in-service; whereas a new combined (two cycle) test procedure is introduced for conventional diesel engines and those diesel engines fitted with oxydation catalysts; whereas a new combined (two cycle) test procedure is introduced for gas-fuelled engi ...[+++]nes and, additionally, for diesel engines fitted with advanced emission control systems; whereas from 2005, all diesel engines are to be tested on both applicable test cycles; whereas the Commission will monitor progress in negotiations towards a worldwide harmonised test procedure;

The emissions to be measured from the exhaust of the engine include the gaseous components (carbon monoxide, total hydrocarbons for diesel engines on the ESC test only; non-methane hydrocarbons for diesel and gas engines on the ETC test only; methane for gas engines on the ETC test only and oxides of nitrogen), the particulates (diesel engines only) and smoke (diesel engines on the ELR test only).

(14) Whereas new provisions for on-board diagnostics (OBD) should be introduced with a view to permitting an immediate detection of failure of anti-pollution vehicle equipment and thus allowing a significant upgrading of the maintenance of initial emissions performance on in-service vehicles through periodic or kerbside control; whereas, however, OBD are at a less developed stage for diesel vehicles and cannot be fitted on all such vehicles before 2005; whereas installing an on-board measurement system (OBM) or other systems to detect any faults by measuring individual pollutants emitted shall be permissible provided that the OBD syste ...[+++]m integrity is maintained; whereas in order for the Member States to ensure that vehicle owners meet their obligation to repair faults once they have been indicated, the distance travelled since the fault is indicated shall be recorded; whereas on-board diagnostics systems must offer unrestricted and standardised access; whereas motor vehicle manufacturers must provide the information required for the diagnosis, servicing or repair of the vehicle; whereas such access and such information are required to ensure that vehicles may be inspected, serviced and repaired without hindrance throughout the European Union, and that competition in the market for vehicle parts and repairs is not distorted to the disadvantage of part manufacturers, independent vehicle-part wholesalers, independent repair garages and consumers; whereas manufacturers of spare or retrofit parts will be obliged to make the parts they manufacture compatible with the on-board diagnostic system concerned with a view to fault-free operation assuring the user against malfunctions;
