TIP! USE THE SAME INJECTOR SIZE AS NOW USED ON YOUR CAR TO AVOID ADJUSTMENTS (SOFTWARE).
TIP! Replace the drying gas filter in good time and regularly:
An average dry gas filter lasts a maximum of 20,000 km. Preferably replace the filter sooner.
This replacement period applies to an average engine capacity of approximately 1.8L. Larger engines use more gas, so the gas filter also needs to be replaced sooner.
It is also possible that at some fill-ups the LPG contains a lot contamination (with oil and fats), making it necessary to replace the filter earlier. Keep this in mind.
The timely replacement / cleaning of the gas filter is necessary to prevent contamination of the gas system and gas injectors.
Background information regarding problem with gas injectors:
In most cases, the problem is caused by the injectors being contaminated with paraffin (oils and fats from the LPG). The filter in front of the injectors must ensure that the injectors do not become dirty quickly. This filter eventually becomes saturated and must be replaced in time. If the filter is not replaced, the paraffin will no longer be captured and end up in the injectors.
It's not like the injectors are leaking or won't open. But the opening and closing times are no longer correct. The injectors remain open longer than they should (with dynamic behavior), so that too much fuel is dosed. (too rich mixture = high CO)
The injectors will then deviate, especially with short injection times (low engine load). The engine starts to run messy and there are too large differences between the injectors. Cleaning the injectors is often pointless, because too much wear has often occurred in the injector, as a result of which the guide of the plunger (sealing disk) no longer has the correct fit. The plunger no longer goes up and down smoothly, but it falters and wobbles.
If the injectors are replaced without changing the filter, the new injectors will quickly become fouled again. (read symptom management, no long-term solution)
