Fuel filter condition monitoring (ffcm) devices innovation on truck diesel engine to prevent filter blocking due to use of bio diesel: B10-b20-b30

Abstract

Currently, diesel fuel uses with a mixture of plant oil, or animal oil are increasingly stifling. To increase awareness of the dangers of global warming, the government strongly supports the presence of biodiesel. Biodiesel in Indonesia, such as B10, B20, or even B30, has been sold in the market. However, it turns out that the use of this mixture of fuels can cause fuel filters to be clogged faster than pure petroleum fuels. Some users are forced to replace the fuel filter faster than before. This can also cause unexpected blockages from diesel users, so we need a measuring device that can measure the level of the block from a fuel filter. The method in this research is to make a filter connecting bracket from aluminium then attach a pressure sensor to the fuel flow in and out, which is connected to the raspberry-based python programming communication system to be able to display the actual pressure data in each fuel flow leading to the fuel filter, after that the results of the innovation were tested directly on the diesel engine which was applied to the truck. The result of the design strength simulation can withstand a load of 15N with von mises stress on the bolt hole of 4.5 N / mm2 or 4.5 MPa the yield strength material applied to the bracket aluminium Alloy 6061 of 55 N / mm2 or 55 MPa, develop the system base on raspberry pi using a python program that will be read by the monitor board and will produce a percentage of a filter block right level of accuracy in reading the program that is with the error of 1,2%, after the tool is fabricated, it is tested directly on the truck diesel engine, namely on a new filter or 0 hours using biodiesel fuel B0, the result is a block filter percentage of 40%, biodiesel B20 has a block filter percentage of 41% and using biodiesel fuel B30 gets the filter block yield by 42%.
