Assessment of dynamic qualities of the G9T engine with common rail system, FED with battlefield-use fuel blends with a biocomponent

The main aim of the study was to experimentally determine the influence of fuel blends of F-34 with biocomponents (rapeseed methyl esters and methyl alcohol) on the performance of an engine with high pressure fuel injection; Common Rail system was used as the example. The study included measurements of useful parameters of combustion and composition of exhaust gas. The studied engine was Renault G9T engine with Common Rail fuel system, fed with the following fuels: fuel base (diesel oil); aviation fuel, code NATO F-34; fuel blends of F-34 and rapeseed methyl esters of higher fatty acids; fuel blends of F-34 and anhydrous ethyl alcohol. The study showed that the parameters of Renault G9T engine with high pressure injection system fed with fuel blends of F-34 with biocomponents changed in comparison to those obtained with the use of the fuel base: diesel oil. As a result of the study it must be stated that fuel blends of F-34 with RME and F-34 with ethyl alcohol can be used as alternative fuel for diesel engines with high pressure Common Rail injection system.
