| Abstract [eng] |
Every car today has a fuel injection system. But time to time it gets clogged and that is stopping the engine from functioning properly. When this system isn't working properly the engine uses more fuel, the engine's overall work gets worse and the risk damaging other components of the engine increases. Fuel injectors are expensive that's why it's better to clean them rather then change. The fuel injector cavities are small and the dirt adhesive is really good. That's why chemical and mechanical cleaning methods are ineffective. This work created an effective fuel injector ultrasound cleaning system. This system helps monitor the whole process and analize the injectors characteristics. An analysis was conducted with different cleaning materials using the made system, Kaunas technology university tools and UAB Remsalis ultrasound washing bath. Before beginning the analysis it was found that the fuel injector nossel was covered in dirt in which the main element was carbon(68.8%), oxygen (23.3%) and other elements (7.9%). Nossel diameter and form are altered and you can see dirt in the tip's microholes. When the analysis was complete it was determined that the ultrasound cleaning system effectively cleaned the fuel injector nossel and the microholes. The overall showed that diesel isn't a good cleaning medium and the most effective cleaning was using alkaline solution \"P-122\". The dirt is cleaned after 2-10 minutes after using 5% water solution. The cleaning method removed up to 93% dirt and injector's microhole diameter and form was restored to factory settings after using the ultrasound cleaning. |
