Size bir link ve "yakit tuketimi standartlari" ile ilgili ingilizce (tercumeye zamanim yok...) bir metni bilgilerinize sunuyorum...
Bu linkten yakit tuketiminizi kisa yoldan hesaplayabilirsiniz...
Ek bir bilgi olarak da, tum arac ureticilerinin "Kyoto Protokolu" (Zararli salinim gazlarinin azaltilmasi konusu) ile kabul edilen "araclarda yakit tuketimi"nin 2010 yilina kadar, her yil belli limitleri asmamasina yonelik bir protokol cercevesinde azaltildigini ve buna uymayan araclarin da ilgili ulkelerce ihrac-ithal ve trafige cikartmama, uretime onay vermeme gibi durumlarla karsilastigini belirtmek isterim...
Asagidaki metinde, Kanada ve Amerika'da uygulanan test standartlarini bulacaksiniz... Tabii ki, laboratuvar ortaminda yapilan bu test sonuclari ile, yol, hava, isi, sartlarinin degisken oldugu gercek ortamlardaki rakkamlar hicbir zaman uyusmayacaktir... Dolayisi ile, bizlere araclarimizin sehir ici ve sehir disi ortalamalari olarak verilen teorik veriler de sadece bir fikir verme duzeyinde kalacaktir...
Federal Test Procedure (FTP)
The Federal Test Procedure (FTP) is a standardized laboratory test method used in Canada and the United States for new vehicle testing. Selected pre-production prototypes of new vehicle models are driven by a trained driver in a laboratory on a dynamometer. The same test parameters and driving cycles are used to ensure that each vehicle is tested under identical conditions, and that the results are consistent and repeatable.
The FTP is composed of two tests; for fuel efficiency purposes they may be referred to as the city test and the highway test.
The city test simulates a 12-kilometre, stop-and-go trip with an average speed of 32 kph and a top speed of 91 kph. The test runs for 23 minutes and includes 18 stops. Approximately 4 minutes of test time are spent idling to represent waiting at traffic lights. This test begins from a cold engine start which is similar to starting a vehicle after it has been parked overnight. When the test is completed, the test cycle starts again with a hot engine start and the first 8 minutes of the test are repeated. This simulates restarting a vehicle after it has been warmed up, driven, and then stopped for a short time.
The highway test simulates a 16-kilometre trip with an average speed of 77 kph and a top speed of 97 kph. The test runs for 13 minutes and does not include any stops, however, the speed varies to simulate different kinds of rural and highway roads. This test begins from a hot engine start.
The FTP is used to certify that vehicles meet the canadian emission standards. In addition, fuel economy estimates may be calculated from the emissions generated during the city and highway tests.
The FTP uses a standardized test fuel with a known carbon content. During a test, carbon compounds expelled in the exhaust are measured and a fuel economy test value is calculated using a specific carbon balance equation.
