oil dilution

oil dilution

The process of adding fuel to the engine oil just before engine shutdown to reduce its viscosity. This facilitates starting the reciprocating engines in cold weather. After the engine has started up, the fuel evaporates and the oil lubricates the engine normally. Oil dilution does not harm the engine. Oil dilution also minimizes the accumulation of sludge deposit within the engine.

Driving pattern is another important factor that needs to be considered while developing DPF system because it directly influences the oil dilution. Low average driving speed and longer idling duration are major concerns in developing countries like India.
High amounts of ethanol can cause higher corrosion rates and more oil dilution than other fuels.
Because the heat generation occurs closer to the DPF, the Vaporizer enables DPF regeneration without oil dilution and reduces thermal losses, helps improve fuel economy compared to vehicles without this system and, therefore, contributes to a reduction in CO2 emissions.
* Possible crankcase oil dilution, requiring more frequent oil changes.
Late cycle post-injection in the engine cylinder, however, may contribute to oil dilution at the exposed cylinder walls, causing accelerated engine wear.
Fifty microliter aliquots of each oil dilution were added to the wells of 96-well plates in a vertical orientation, and 10 [micro]l aliquots of each ketoconazole dilution were added in a horizontal orientation so that the plate contained various concentration combinations of the two compounds.
"Unlike systems utilizing engine post-injection, the Atomizer does not contribute to engine oil dilution and thus has no detrimental effect on engine durability."
For this reason, wall wetting, oil dilution and subsequently changes in the oil properties by impinging fuel seem to have a significant influence in terms of accumulation and detachment of oil-fuel droplets.
According to the company, validation tests have proven the vaporizer's effectiveness in carrying out frequent regenerations, without oil dilution and with lower fuel consumption.
