Fuel which is used in electronic fuel injection engines to provide Euro 2 Standard Emission must accomplished category 2 World Wide Fuel Chapter specifications. In arranging specification for the fuel, one of the parameter is fuel injector cleanliness according to ASTM D5598 by measuring flow loss at the injector.<p> <br /> <br /> <br /> The objective of this research is to produce an injector testing rig which can measure the flow and check the injector spray quality. The flow that is occurred at the injector analyzed and compared with ASTM D5598 standard.<p> <br /> <br /> <br /> The coverage of this final assignment is to produce injector testing rig and to determine the capability of the device to measure the flow and check the injector spray quality. Further researches are needed to improve injector testing rig after early testing has been done.<p> <br /> <br /> <br /> The test of the device are conducted twice to recognized the capability in measuring flow, repeatability signal delivery from PLC (Programmable Logic Control) to the injector, checking fluid flow system and checking the injector spray quality. 4 injectors from kijang EFI 1800 cc are used for the first test and 4 injectors from Honda CRV 2000 cc are used for the second test.<p> <br /> <br /> <br /> The result of the first test are maximum range of fuel flow is 3.74% at injector 4 and average fuel flow deviation is 2.14%. The result of the second test are maximum range of fuel flow is 6.35% at injector 4 and average fuel flow deviation is 86.35%. According to ASTM D5598 standard, maximum average fuel flow deviation is 3% and maximum range of fuel flow is 1%. The spray pattern of the injector can be visually checked and recorded. The spray pattern is analyzed and compared according to ASTM D5598 standard.<p> <br /> <br /> <br /> Injector testing rig can work well and there are no problems occurred during the testing also able to detect injector failure by calculating range of fuel flow with maximum 1% and by calculating average fuel flow deviation with maximum 3% according to ASTM D5598 standard.
