This work focuses on the prevention from knock in the case of SI engines supplied by natural gas network. The effect of two inert gases (N2 and CO2) adjunction is experimentally studied. The added quantities are between 0% and 25% in volume for N2 and between 0% and 15% for CO2. A significant increase of the Knock Limited Spark Timing (KLST) is measured in all the cases. A twice-higher augmentation is noted when CO2 is added compared to N2 for an equivalent volumetric concentration. The overall augmentation varies between +1 to +6 °CA depending on the operation. Finally, a law for predicting the KLST augmentation implied by the adjunction of inert gases is deduced from all the measurements.

AbstractThe article describes the technology of the “hydraulic piston”, as well as the studies that confirm the viability of this technology, implemented in various devices, designed to compress natural gas (CNG) and biomethane (bio-CNG), to accumulate CNG and bio-CNG, to deliver bio-CNG from the production site to the point of its injection into the natural gas network or to the vehicle fuelling stations to fill the Natural Gas Vehicles (NGV). The article presents prototypes of personal fuelling devices and mobile fuelling systems developed by Hygen Ltd. (Hygen), thereby showing the potential of the technology to contribute in the deployment of alternative fuel infrastructure and into the global GHG emissions reduction, mainly in the transport sector.
