The oil product testing department of the Cummins headquarters in the United States issued a test report on the product name of the designer's CNG/LPG for the unified lubricants. The results showed that the uniform lubricant met the (Cummins) CES20074 standard and was consistent therewith. Engine oil.
According to reports, the dual-fuel engine petrol/LPG can provide sufficient protection for the engine. Proper ash can prevent wear but does not cause spark advance. The bi-fuel engine gasoline/CNG requires a total alkali number of 6-8, which is equivalent to 0.6%-0.8% of sulphated ash. The ash requirement is to meet the requirements of compressed natural gas. Especially for compressed natural gas, the lubrication of the valve seat is reduced because the gas does not have the lubricating function of the liquid, and a certain ash content in the lubricating oil can prevent the valve seat from being worn out. However, due to the high temperature of the natural gas engine and its complete combustion, lubricating oil with high ash content tends to increase in fouling and lead to premature ignition, so sulfate ash should be appropriate.
The lubricating oil produced by Dongfeng Cummins Engine Engine Oil is imported deep hydrogenation refined base oil and new low ash natural gas additives, refined through advanced pulse blending technology. With excellent deposit control and anti-oxidation, anti-nitrification ability, effectively extending the service life of lubricating oil. This product uses a new low ash natural gas engine oil additive, which can effectively prevent valve carbon deposition, wear and ablation, and prevent pre-ignition. The use of friction reducing agents reduces the coefficient of friction, provides energy savings for engine operation, and extends engine life.
