Abstract: Tyrimas buvo atliktas naudojant standartinį Volkswagen Passat 1,8 l darbo tūrio, keturtaktį, 4 cilindrų benzininį variklį, sujungtu su hidrauliniu apkrovos stendu D-4. Rezultatai parodė, kad varikliui veikiant benzinu ir E10, E25,E50,E85 mišiniais katalizatorius praktiškai 100% konvertuoja visus anglies monoksidus CO esančius deginiuose. Katalizatoriaus CH konvertavimo koeficientas, varikliui veikiant E10, E25 ir E50 mišiniais, gautas didesnis, nei varikliui veikiant benzinu. Varikliui veikiant E85 mišiniu KCH buvo 2 kartus mažesnis, nei naudojant benziną, tačiau CH emisija prieš katalizatorių taip pat buvo ~ 2 kartus mažesnė. Taigi, aplinkos taršai nesudegusius angliavandenilius nepaliktų, naudojant E85 mišinį. Naudojant benzino-etanolio mišinius, pablogėja katalizatoriaus NOx konvertavimo koeficiento efektyvumas ir padidėja aplinkos tarša azoto oksidais
This article presents the test results of four cylinder, 1.8 liter gasoline engine operating with gasoline fuel and bioethanol fuel blends. There was five fuel blends: 100% gasoline, E10, E25, E50 and E85. Analysis of the data obtained shows that catalyst convert almost 100% of carbon monoxide (CO) while engine operating with all fuel blends (100% gasoline, E10, E25, E50 and E85). The CH coefficient of catalyst was measured bigger while engine was operating with E10 and E25 fuel blends than comparing with 100% gasoline. Engine operated with E85 fuel blend shows that KCH was two times smaller than engine operated with 100% gasoline, also CH emission was two times smaller before catalyst. Using gasoline – bioethanol fuel blends, conversion coefficient of NOx is decreasing and also increasing air pollution of nitrogen oxides
