A gaseous-fuel slave control unit from IAV provides the means for upgrading gasoline concepts to run on gaseous fuels quickly and cost-effectively without having to modify the existing engine control unit. This system, which is composed of  the control unit, the gaseous-fuel component set, the master control unit, and the gasoline components, makes it possible to meet the current and future requirements of emissions legislation. Large-scale mass production of the slave control unit is scheduled to start at production partner MGH in the spring. In the system, the original engine control unit works with the slave control unit. The signals for actuating the gasoline injectors are first fed to the control unit for the gaseous-fuel drive. A high-precision analysis unit processes the signals and computes the necessary adjustments, i.e., the optimum gaseous-fuel injection times, which, depending on operating point, may differ from the values for gasoline operation. The system electronics use the sensor values from the original engine management system as well as additional parameters such as pressure and temperature in the gas rail. Because the original gasoline calibration is left unchanged, manufacturers can use the same gaseous-fu­el slave control unit for different engine versions.
