Importance Of Lubrication And Volvo Penta Generator Special Oil

Is engine lubrication oil important? I think most people will answer: important, very important. So why? In short, engine oil is engine lubricating oil, which can lubricate, clean, cool, seal and reduce wear of the engine. Engine is a very complex machine component, which is composed of a large number of important moving parts, such as piston, crankshaft, camshaft and rocker arm assembly. These components have fast movement speed and poor environment, and the working temperature can reach 400 ℃ to 600 ℃ or even higher. Under such harsh working conditions, the engine oil acts as a protector to protect these parts of the engine in an all-round way so that they can work normally. The main functions of engine oil are:

General functions: reducing wear and keeping clean. Cooling, rust prevention, sealing and vibration isolation.

Special function: prevent particle accumulation, prevent cylinder pulling, effectively lubricate at high temperature and start at low temperature.

Prevention of carbon deposition: piston ring groove, piston skirt, air valve.

Since the role of engine oil is so important and has to meet so many functions, how does it do it? Engine oil is a complex synthetic product. The oil manufacturer selects high-quality base oil and adds various additives according to the functions that the engine oil needs to meet, so as to obtain the required synthetic product with a scientific and reasonable ratio. The high-quality and qualified engine oil can achieve less engine deposition, less wear of various components and more lasting engine oil performance.

So there are so many oil brands, what kind of oil should I choose? How to choose the right engine oil? The selection of engine oil needs to take into account two important index grades: quality grade and viscosity grade, which can be found on the outer packaging label of the oil barrel.

1. Quality grade

There are two general international reference standards for the quality grade of diesel engine oil:

API grade (API standard), such as CG-4 \ CH-4 \ CI-4.

ACEA standard (European Automobile Manufacturers Association standard), such as E3 \ E5 \ E7.

The higher the value, the higher the grade of the engine oil. When selecting, you must select the engine oil that meets the standard according to the operating instructions of your engine. The higher grade of engine oil can be downward compatible. However, if you choose the low grade engine oil when you need the high grade engine oil, it will affect the use of the engine and may damage your engine.

2. Viscosity grade

The viscosity of single viscosity engine oil is greatly affected by the change of temperature. The higher the temperature, the thinner the engine oil, and the lower the temperature, the more viscous the engine oil. In order to meet various operating conditions of the engine, good lubrication performance can be obtained at different operating temperatures and ambient temperatures. The engine oil uses oil with composite viscosity, which is expressed by XX W - YY according to the international general standard, The number in front of W indicates the low-temperature performance, and the number after W indicates the high-temperature performance of the oil. As shown in the following figure: for example, the minimum ambient temperature that 15W-40 grade engine oil can withstand in winter is minus 15 degrees. Therefore, when selecting engine oil, be sure to consider the actual situation of the place of use and select the engine oil with appropriate viscosity that can meet the minimum temperature requirements in winter. If the wrong viscosity grade is selected, the engine will have the fault of serious insufficient lubrication in winter, damage the engine in serious cases.

As mentioned above, there are various technical specifications and requirements when selecting engine oil. End users need to have a lot of professional knowledge to select qualified engine oil. It is a pity that there are many unnecessary serious engine faults caused by the wrong selection of engine oil specification. For new and old users of Volvo PENTA diesel generator, we solemnly recommend and strongly recommend that you use Volvo PENTA special engine oil with high standard and high quality guarantee.

What is Volvo PENTA special oil? Volvo PENTA special oil is a more stringent oil performance standard VDS standard launched by Volvo Group Based on the original API and ACEA industry standards and according to the structure and performance characteristics of Volvo PENTA engine. In addition to the specified tests required by API or ACEA specifications, the Volvo special oil produced according to this standard also has other specific Volvo tests, such as piston sedimentation control test, oil change cycle test and a series of rigorous tests. The oil produced according to this standard not only has the performance far beyond that of the oil of the same grade. Moreover, it is more suitable for Volvo PENTA engine.

Volvo PENTA VDS special oil has three different grades of oil: VDS-2, VDS-3 and VDS-4.5. Please consult a professional authorized agent of Volvo PENTA to select the appropriate oil for your engine. I hope Volvo PENTA special oil can take better care of your Volvo diesel generator and provide strong and continuous power for your equipment.
