LPG injections often fail. What are the reasons LPG injectors fail? How can we tell if an LPG injection has failed?
No matter how good a product may be, it has a limited lifetime. LPG injectors have different service lives depending on their quality standards. Some injectors have a 150,000-km service life, while others may last up to 300,000. km or even 400,000 kilometers. The Keihin injector, Japan’s most well-known brand for LPG injectors can run for over 240,000 km and can be used in 290,000,000 cycles. This injector can be used in LPG systems like Prins or Kitmtm.
LPG injectors, which are mechanical products, have a sensitive structure. These parts are very hardy if provided with the proper protection. These negative situations can cause irreparable damage to injectors.
1- Bad fuel and additives
This means that the fuels you buy from stations that haven’t been maintained properly and checked are not clean, low quality, and may contain harmful additives. Bad fuel can clog your filter and cause damage to your injectors. If you use additives in fuel, certain substances can cause freezing and sedimentation which will stop your injectors from working properly.
2- Maintenance and Failure to Change Filters on Time
LPG System equipment must travel 10,000 to 15,000 kilometers in order to function properly and perform its duties. It needs to be maintained on a regular basis. It is important to maintain the filter change schedule. If there is a problem, it is identified and corrected. You can clog your system by not changing your filter on time. This will lead to your injectors failing. Even if you don’t have any dirt, the paper filter can become deformed and lose its durability, which can cause fuel dirt to leak into the injectors.
You should also remember to keep the original filter in your system. LPG spare part dealers sell maintenance kits for between 3-5 and 3.5 TL. Unauthorized service can cause damage to your system.
Also, ensure that you follow the system’s warranty booklet. It must be maintained on time. Neglecting small transactions could endanger your safety and life.
3-Assembly Error
It is possible that the master who installed your vehicle did not place the injectors in a suitable position. Your injectors can be damaged if the LPG is not connected correctly.
How can you tell if the LPG Injector is damaged?
First, make sure you check the gasoline engine. You don’t need to worry about the LPG system if the problem persists in gasoline. The LPG system can have problems if the gasoline engine is working properly. This could include misfiring when switching to LPG, shaking at start-up, misfiring when the vehicle is idle, vibrations and bumps in the revs.
If your vehicle is experiencing problems, please take it to the nearest service center or repair shop for the brand you use. Connect the ECU (brain), of the LPG System to your computer to view errors and values. The software of the system displays the problem on the screen. It also gives the error code. On the screen, the working principle of injectors is clearly displayed. The millisecond values can be clearly seen. It is easy to see which injector is affected and how to fix it.
You will likely experience the following symptoms if your LPG injector stops working:
