Comlurb, the municipally owned trash collection company serving Rio De Janeiro, Brazil, has begun using O2Diesel’s proprietary ethanol-diesel fuel blend in its fleet of trash-hauling vehicles.
Comlurb’s use of O2Diesel represents the first time that ethanol-diesel fuel has been used in a commercial on-road truck application in Brazil.
Comlurb, one of several municipal fleets, was selected by Rio de Janeiro as the pilot fleet to verify the suitability of O2Diesel for all municipal fleets. The initial verification process is expected to last approximately three months, and involve 15 diesel-powered trucks. Comlurb operates 300 diesel powered vehicles consuming around 2 million gallons of diesel fuel annually. The O2Diesel fuel used by Comlurb is blended and delivered by state-owned Petrobras/BR, the largest oil and fuel distribution Company in Brazil.
O2Diesel uses 7.7% ethanol, with up to 1% proprietary additive and a cetane improver. Cetane is a measure of a fuel’s ignition delay—the period between the start of injection and start of combustion of the fuel. Higher cetane fuels will have shorter ignition delay periods than lower cetane fuels, and shorter delay is better.
