PD CEN/TR 16569:2013CEN/TR 16569:2013 (E) 4 1 Scope This Technical Report describes a study executed to evaluate the performance of r
13、epresentative vehicles of current and recent production when operating on petrol fuels containing up to 10 % (V/V) ethanol. Vehicle performance evaluations included regulated and evaporative emissions as well as hot and cold weather driveability. The testing procedures used in each of the three main
14、 vehicle studies were adapted to the requirements of the testing facilities. The studies were designed to demonstrate whether a relaxation in the E70max, E100max, and VLI limits in EN 228 would introduce unacceptable vehicle driveability or regulated emissions performance problems. The results were
15、used to advise CEN/TC 19/WG 21 on the revision of the EN 228 petrol specification 1. A procedure for future revision of EN 228 (see Annex A) was also developed. 2 Background The former European EN 228 specification 1 included volatility requirements for unleaded petrol in order to ensure good perfor
16、mance of vehicles in real world driving conditions. These requirements were put in place following extensive technical studies in the 1990s at a time when vehicles were more sensitive to volatility than they are today and when blending of oxygenates, like ethanol, was not widespread. Different petro
17、l volatility classes are included in the EN 228 specification that depend on climatic conditions. Minimum and maximum volatility limits for summer and winter petrols are included as well as additional limits for spring and autumn seasonal transitions. Since these volatility requirements were put in
18、place, the use of oxygenate blending components, such as ethanol and ethers, has increased, in response to the EU Renewable Energy Directive (RED, 2009/28/EC 3). This Directive requires Member States to use at least 10 % renewable energy in transport fuels by 2020. Although biogas, renewable electri
19、city, and other energy types are encouraged, only conventional and some advanced bio-blending components are likely to be available in sufficient volumes by 2020 to meet the mandate. The major bio-derived blending components until 2020 are likely to be bio-ethanol produced from sugar fermentation, e
20、thers manufactured from bio-ethanol or bio-methanol, and esters and hydrocarbons produced from vegetable oils and animal fats. Blending ethanol into gasoline at low concentrations alters the volatility characteristics of the resulting blend and the fuel refining and blending process shall account fo
21、r this effect. In addition to increasing the vapour pressure of the ethanol/petrol blend, ethanol also changes the shape of the blends distillation curve. This has the potential to impact the vehicles regulated emissions and driveability performance in cold and hot weather. Furthermore, any change i
22、n the blends distillation characteristics due to ethanol addition must be compensated in the refinery by changing the composition of the hydrocarbon-only petrol mixture into which the ethanol is ultimately blended. Following the publication of the EU Fuels Quality Directive (FQD, 2009/30/EC 3), CEN/
23、TC 19 reviewed the European EN 228 unleaded petrol specification in order to enable the higher ethanol blending envisioned by the FQD from 5 % (V/V) up to 10 % (V/V). As input to this review, CEN/TC 19 Working Group 21 (WG 21) reviewed a 2009 study of published literature 4 on the effect of blending
24、 up to 20 % (V/V) ethanol on E701and E1002volatility parameters, as well as on hot and cold weather vehicle driveability performance. This literature review was completed to better understand the observed effects on the petrol distillation curve due to the addition of higher levels of ethanol to pet
