Research on the influence and the methodology of the calibration process for Diesel-LPG dual fuel supply systems

The paper raises the problem of the lack of a methodology for how to calibrate the Diesel-LPG dual fuel system in the literature and the lack of information about the impact of calibration method on reducing the amount of consumed Diesel. Its purpose is to study such a system in which a part of Diesel is replaced by a mixture of propane and butane and to establish methodology of choosing the calibration parameters to ensure the maximum reduction in the amount of burned Diesel while keeping the engine durability. The results of the research done on the road and chassis dynamometer, carried on the van type vehicle, allow to conclude that the reduction in the amount of consumed Diesel may vary by up to 25% between different calibration methods.
