Witam,
postanowilem utworzyc ten temat, aby rozwiac watpliwosci z zwiazane z tworzeniem sie osadow na zaworach dolotowych itp. Ponizej zamieszczam podsumowanie badania:
1. Deposit forming tendency is one of the most relevant
parameter which causes drivability problems, increases
fuel consumption and emissions as well as affects the
engine durability.
2. Engine design and parameters, gasoline composition,
engine operating conditions and deposit control additives are all critical factors that influence engine deposit
levels.
3. Taking into consideration engine operating conditions,
deposits are formed at lower speeds and loads. At higher
engine speed and/or load the deposits either flake or
burn off.
4. In modern PFI engines with low lubricating oil consumption, engine internal deposits are derived primarily from
the fuel, and to some extent from the lubricating oil.
5. It has been established that lubricating oil is a significant
factor in the amount of IVD formed in the GDI engines.
6. IVD and CCD formation in GDI engines is greater in
comparison to PFI engines.
7. Engine operating conditions that tend to increase intake
valves and combustion chambers surface temperature
lead to a reduction of deposit formation.
8. The most important lubricating oil component for deposit
formation is the base oil. Increasing the high molecular
weight and low volatility content of the oil increases
deposit formation.
9. The fuel treated with additives blended at an IVD control
dosage produces more CCD than the base fuel alone.
10. The use of modern deposit control additives is critical
to protect engines against both the intake valves and
combustion chambers deposits.
11. Accumulation of IVD and CCD leads to a deterioration
engine performance and vehicle drivability.
12. Different fuels might take significantly different times
to reach stabilization in the same engine. Particularly
long time is required for stabilization of CCD in case of
base fuel. The presence of additives in fuel reduce this
time significantly. So, too short duration tests could be
misleading if the test duration is small compared to the
time required to approach stabilization.
Wiec jak powyzej, najwieksze znaczenie ma styl jazdy, paliwo wysokiej jakosci (odpowiednio dobrane dodatki bazujace na miedzy innymi polieteroaminy tzn. PEA) oraz srodek smarny czyli masa czasteczkowa mieszaniny olejow bazowych (najlepiej olej z duza zawartoscia PAO 4 cSt). Oprocz tego polecam zapoznac sie z calym artykulem.
Pozdrawiam
