Lewisöljyjä

Lewisöljyjä is a Finnish term referring to lubricating oils that are specifically designed for use in Lewis engines. Lewis engines, also known as Lewis atmospheric engines, are a type of internal combustion engine that operates on a unique thermodynamic cycle. These engines were developed by Charles Lewis in the early 20th century and are characterized by their distinct design and operational principles, which require specialized lubrication.

The lubrication requirements for Lewis engines differ from those of more conventional engines. The specific operating conditions, such as temperature, pressure, and the presence of unique combustion byproducts, necessitate the use of oils with particular properties. These properties might include specific viscosity grades, thermal stability, and resistance to oxidation and deposit formation.

While the precise formulations of Lewisöljyjä are often proprietary to the manufacturers or service providers for these engines, their purpose is to ensure efficient operation and longevity of the engine's moving parts. This includes components like pistons, cylinders, and crankshafts. The correct lubrication is crucial for reducing friction, dissipating heat, and preventing wear.

The availability of Lewisöljyjä is generally limited, reflecting the niche nature of Lewis engines themselves. These engines are not widely used in modern applications, and their maintenance often requires specialized knowledge and access to specific parts and consumables. Therefore, sourcing appropriate lubricating oils can be a challenge for owners and operators of Lewis engines.
