Transdev STAO formerly Veolia Transport – Diesel engine cleaning
On 10 January 2003, Mr. Alain Delaunay, director of the Laval city bus network – STAO – and Mr. Daniel Pointeau, technical manager, took the decision to stop treating the fuel tank with the standard chemical additive they had been using until then to fight bacteria and frost.
At the same time, the treatment of the 50,000 liters of diesel fuel stored in the depot and destined for a fleet of about 80 buses was started with the XBEE enzyme.
The first effective return of the XBEE treatment in 2004
After one year of treatment, the following results could be verified:
- At no time has there been any technical incident attributable to the XBEE enzyme.
- The conformity inspection of the tank carried out by the specialist company GDDC e.mat on 7 July 2003 showed the effectiveness of the XBEE enzyme very clearly.
- After an initial drop in consumption in 2003, there has been a further reduction in 2004 of around 3.9 % for the entire fleet. Of the twelve months of 2004, eleven are down; when the exceptional weather conditions of 2003 are known, the capacity of the XBEE technology to reduce engine consumption can be measured even better.
