The standard specifies three kinds of ethanol gasoline, namely E10 （90 RON）, E10 （93 RON） and E10 （95 RON）. There were ethanol gasoline grades （90 RON and 93 RON） and conventional unleaded gasoline（97 RON） available in the areas where tests were carried out. Vehicle owners were worded about the harmful action of ethanol to their vehicles because of lack of knowledge regarding ethanol fuel, and they only refueled their cars with conventional 97 RON unleaded gasoline. This idea might cause unnecessary costs to customers and could bring about difficulty to the tests as well. Besides, some other technical questions emerged during the experimental application of ethanol gasoline, such as water content, ethanol content in gasoline, etc. Based on the experiences accumulated during the application tests, the national standard GB 18351-2001 ＂Ethanol Gasoline for Motor Vehicles＂ was revised. The revised edition is designated as GB 18351-2004.展开更多

This is the main reason that during eighties of the last century, a special attention has started to be paid on pollution emissions from vehicles. It is important to note that most of the current emissions are formed directly and are present in urban areas. The aim of this research was to determine the emission of pollutants in the territory of the Republic of Kosovo, when circulates more than 380,000 motor vehicles. Taking into consideration the daily traffic jam, and the fact that gasoline engines are responsible for most emissions of CO, while diesel engines for NOx emission, the conclusion arises that there is necessary a special dedication to the emission of pollutants and to the definition of the measures to reduce or control them. Based on the performed tests and realistic assessment of the overall situation in the Republic of Kosovo, the current situation on the amount of pollution was compared with development countries in the region as a matter in the research. The results obtained, suggest to the most important causes that increase pollutant emission from motor vehicles and offer actions to keep the same level or to reduce them.展开更多

In this study, the authors carried out performance tests on the direct use of waste cooking oil using a car with a heater unit, Moreover, the authors carried out long run driving on road tests in five years using a public car of Minami-Aizu Town in Fukushima Prefecture and analyzed the case of troubles and clarified the availability and problems of SVO vehicles. As a result, the car with a heater unit shows similar performance in both cases using vegetable oil or diesel fuel as fuel. The tested SVO vehicle of Minami-Aizu Town could be driven 38,127 km mainly by waste vegetable oil with a total driving distance of 52,293 km in long run driving tests in five years, and decreased about 3,813.5 liters of light oil which corresponds to 9.99 t of CO2.展开更多
