The use of quality engine lubricating oils, combined with appropriate oil drain and filter change intervals, is a critical factor in maintaining engine performance and durability.

Cummins Inc. recommends the use of high-quality SAE 15W-40 heavy-duty engine oil, such as Valvoline® Premium Blue®, which meets performance specifications as listed below.

NOTE: In areas where CH-4/SJ or CG-4/SH oils are not available, refer to Oil Drain Intervals in Section 2.

A sulfated ash limit of 1.0 mass percent is suggested for optimum valve and piston deposit and oil consumption control.

As the engine oil becomes contaminated, essential oil additives are depleted. Lubricating oils protect the engine as long as these additives are functioning properly. Progressive contamination of the oil between oil and filter change intervals is normal. The amount of contamination will vary depending on the operation of the engine, kilometers or miles on the oil, fuel consumed, and new oil added.

Extending oil and filter change intervals beyond the recommendations will decrease engine life due to factors such as corrosion, deposits, and wear.

Special “break-in” engine lubricating oils are not recommended for new or rebuilt Cummins engines. Use the same type of oil during the break-in as is used in normal operation.

The use of low-viscosity oils, such as 10W or 10W-30, can be used to aid in starting the engine and in providing sufficient oil flow at ambient temperatures below -5°C [23°F]. However, continuous use of low-viscosity oils can decrease engine life due to wear. Refer to the accompanying chart.

If an engine is operated in ambient temperatures consistently below -23°C [-9°F] and there are no provisions to keep the engine warm when it is not in operation, use a synthetic CH/SI or CH/SK or higher API classification engine oil with ade- quate low-temperature properties such as 5W-20 or 5W-30.

The oil supplier is responsible for meeting the performance service specifications represented with its product.

Use low-silicate antifreeze that meets ASTM4985 (GM6038M specification) criteria. Fully formulated coolant must meet ASTM D-6210/D-6211. Cummins Inc. recommends using either a 50/50 mixture of good-quality water and fully formu- lated antifreeze, or fully formulated coolant when filling the cooling system.

Good-quality water is important for cooling system performance. Excessive levels of calcium and magnesium contribute to scaling problems, and excessive levels of chlorides and sulfates cause cooling system corrosion.

ACUM210, ACUM110, ACUM65, ACUM185, ACUM140 specifications

Armstrong World Industries has established itself as a leader in the design and manufacture of innovative ceiling and wall solutions. Among their notable acoustic ceiling offerings are the ACUM84, ACUM210, ACUM65, ACUM140, and ACUM185 tiles. Each of these products is engineered with distinct features and technologies aimed at enhancing acoustic performance, durability, and aesthetics in various commercial spaces.

The ACUM84 is designed for spaces that prioritize sound absorption and overall acoustic quality. It utilizes advanced sound-dampening technology, making it suitable for environments such as offices, schools, and healthcare facilities. This tile achieves a high Noise Reduction Coefficient (NRC), effectively minimizing sound reverberation, which is essential for maintaining concentration in busy settings.

Similarly, the ACUM210 offers enhanced acoustic properties but with a focus on durability. This tile is constructed with a robust material that is resistant to impact and moisture, making it an excellent choice for high-traffic areas. The fabric-like texture not only adds aesthetic value but also improves its sound-absorbing capabilities, contributing to a quieter environment.

For those seeking a versatile solution, the ACUM65 is an ideal option. This tile is lightweight yet durable, making installation straightforward. Its ecological design ensures minimal environmental impact while providing superior acoustic performance. The ACUM65 is particularly well-suited for retail spaces, where customer experience can be significantly enhanced by better sound control.

ACUM140 is engineered for flexibility and design versatility. With a range of finishes and colors, it allows architects and designers to incorporate acoustic solutions that harmonize with the overall aesthetic of the space. Its high NRC rating ensures a calm auditory environment, making it an excellent fit for restaurants and auditoriums.

Lastly, the ACUM185 combines aesthetics with functionality, offering a sleek design while maintaining outstanding sound absorption capabilities. It meets the demands of contemporary styling without compromising performance. This tile is particularly favored in corporate environments where aesthetics play a crucial role in branding and employee satisfaction.

In conclusion, Armstrong's ACUM product line, including ACUM84, ACUM210, ACUM65, ACUM140, and ACUM185, showcases technologies and characteristics that cater to a variety of applications.
