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
