摘要：This paper demonstrates the production and distribution system of biodiesel made from left-over frying oil in Brazil, as well as the behaviour of this fuel in the cargo shipment system, based on the tests conducted through two hospital garbage collection vehicles in the City of Rio de Janeiro. These vehicles were monitored on a daily basis, one of them fuelled by a blend of frying oil biodiesel at 5% and the other with 100% mineral diesel, as a benchmark. Through this monitoring campaign, information was collected on consumption, performance and drivability, as well as mechanical anomalies and wear and tear. The fuel injection systems were tested and sealed by their manufacturer, Bosch, before the tests began and were then returned for analysis and final testing. A similar procedure took place at the Technology Research Institute (IPT) with the motor of the vehicle using the B5 mixture.
