The long time needed for the application and the money involved are some of the main obstacles preventing the CNG vehicles market penetration, costs are always too high and application time always too long compared with the relatively small volumes. Besides the activities to be carried out on the original engine control system to integrate the gas system are unwelcome by the OEM as they require a re-validation of already validated components/systems. This issue became more critical since the EOBD system has been installed into the vehicles as the extremely heavy validation activity are jeopardized by the gas system and the major part of the calibration/validation work shall be repeated. A new gas control system has been developed with the aims to achieve the best performances in terms of power, driveability, emissions, without any modifications on the OEM system, very short application time and costs. It's worth to note the new system is absolutely transparent to the original EOBD system.
