Most car engines today are made of cast iron or a similar metal. The engine heavily relies on oil lubrication to keep it running properly and for a long time. There are many moving parts inside the engine, which make contact and need to be separated by a thin film of oil so that they don't wear out and overheat.

When the car is started initially, it takes a few seconds for the oil to build up pressure and to cover all moving parts. The colder the weather outside, the longer this process takes, because when oil is cold, it thickens and cannot reach into the small gaps between the moving parts. Those few seconds during which moving parts are starved of oil lubrication are the time when you engine wears out the most.

Shown in fig.1 below are two imaginary metal surfaces that are sliding over each other. A similar process goes on inside your engine between the pistons and the cylinder walls. On a microscopic level the metal surfaces

Basic properties of the newly created ceramic surface:

• Coefficient of linear thermal expansion: 13.6-14.2
• Friction coefficient: 0.003-0.007 (dry without lubricant)
• Micro hardness: 690-710 HV
• Shock resistance: 50 kg/mm²
• High corrosion resistance
• Clear isolating and heat-proof properties
  

One universal truth about cars is that it is important to allow the engine to warm up prior to driving the car. It is also wise not to push the engine too hard until it has reached operating temperature. In support of this notion some high-end automobile manufacturers even implement a restriction in their cars, which lowers the red line of the engine until it has completely warmed up. All of this is important for

are edgy and uneven, and the lack of oil lubrication causes the two sides to touch, breaking off small pieces of metal in the process. This is what causes the excessive wear during initial startup.

In the bitter Canadian winter, this process is amplified because of two major factors:

• The colder it is outside, the thicker the oil becomes and the longer the engine is starved from lubrication after starting it up.
  
  
• The colder the metal of the engine is, the more brittle it gets, causing it to wear out even faster if it is not properly lubricated.

This is where RVS can make all the difference (if you are not familiar with how the RVS ceramic is embedded onto the metal surface, you can read here more about it or watch a flash movie illustrating the process). Fig.2

shows how the ceramic layer covers all gaps and inequalities in the metal, thereby completely smoothing out the surface. The new supersmooth surface wears out much slower than the original metal surface with its sharp edges and peaks. There is much less friction between the moving parts. The new RVS surface is so smooth that the engine could be ran without any lubricant for an extended period of time without incurring any damage.

Even in the coldest weather outside, RVS Technology benefits your engine in three major ways:

• The smooth RVS surfaces virtually eliminate wear due to fiction during the initial few seconds of starting the engine when there is oil starvation
  
  
• The lowered friction inside your engine will make it much easier for the engine to be cranked, reducing the potential problem of cold starts.
  
  
• The new RVS surface is stronger and has lower friction properties than the metal that it covers, therefore it wears out very slowly and significantly extends the life of your engine.

In conclusion, RVS Technology is simply the best preventative maintenance that you could get for your engine during the winter. Avoid cold start trouble, protect your engine from excessive wear, and extend its life!
