E85 degalais veikiančio variklio darbo rodiklių tyrimai

Abstract

Biofuels atlernatyvus as a source of energy is one of the urgent topics of today. Bioethanol can be used in motor vehicles, the direct method, such as Brazil, where clean (undehydrate) bio-ethanol is used in blends with gasoline. The most used bio-ethanol-gasoline blend is E85, which consists of 85% bioethanol and 15% gasoline. E85 fuel economy at all engine operating modes obtained gidesnės than gasoline: on average 14% higher at low and moderate load, and on average 7.5% higher at high load. 100-160 ppm in the engine exhaust gases CH levels are relatively low and its variation range of 50 ppm is normal. CO emissions from the engine running on E85 fuel, received on average 4.5 times lower than using the A95 gasoline. CO emission fluctuations may be related to the engine characteristics are replaced by the distribution of gas phases, which changes moments could coincide with the measurement modes. This requires a more detailed analysis
