REDUCING FRICTIONAL LOSSES! IS THE INVESTMENT IN DEVELOPMENT REALLY WORTHWHILE?

Reducing direct friction losses between the surfaces of sliding engine parts has--in many cases--only little influence on the effective fuel consumption, especially in engines with a high load-factor. Therefore, the higher expenditures in development and production result in a poor cost/benefit-relation. But in quite a lot of cases friction losses can be reduced by shifting the speed- and load-range of the engine. Together with optimizing oil flow and viscosity behaviour advantages on behalf of the motor cycle-process as well as of engine behaviour and engine life are reached, thus reducing fuel consumption even further together with better engine performance. Some examples are given and discussed in detail.
