COMBUSTION ENGINES

With an unbelievable number of internal combustion engines in service, even the smallest improvements in tribological efficiency and durability can have a major effect on the world fuel economy and the environment in a long-term.

The cylinder and piston are the most critical part of the combustion engine. In this role, these parts of the engine accounts for a large portion of total machinery friction, which illustrates the importance of a well-engineered cylinder assembly.
The increase in specific performance of gasoline and diesel engines, require a need for better and economical fuel consumption and therefore a reduction in cylinders-pistons friction as well.
Validation ensures that the system dynamics work together as a whole: the tribological interface of the piston rings and cylinder liner; the gas dynamical system of the piston rings as well as the piston and power transmission system of the piston, piston pin and connecting rod.
The implementation of complex tribological methods and the challenge to use these tools to shape the piston engines, will help the future possibly herald the most significant and exciting phase in the evolution of vehicle manufacturing.

As explained in the chapter “Tribology and engine oil” on this website, ENVIRO₂PRO offers the possibility to improve the lubricious properties of engine oil and other lubricants in order to lower the total machinery friction and thus better dynamic performance and lower emissions of the engine.
