Optimisation of lube oil consumption in transient engine operation is gaining increasing attention from engine developers. Engine operation in extended stop-and-go phases can sporadically lead to unexpected oil consumption problems for inner-city driving.

Exemplary results in this paper reveal that knowledge about steady-state LOC is one important element but not sufficient for further LOC reduction on modern engines. Besides the general influence of speed and load during steady-state operation LOC behavior is affected by dynamically induced LOC mechanisms, which can contribute significantly to overall LOC. As a result, optimum engine component development includes evaluation of LOC behavior for stedy-state and dynamic engine operation.

Partly competing objectives, as low fuel consumption, low friction, long oil maintenance rate, and at the same time lowest exhaust emissions have to be fulfilled. Diminishing resources, continuously reduced development periods, and shortened product cycles yield detailed knowledge about oil consumption mechanisms in combustion engines to be essential. There are different ways for the lubricating oil to enter the combustion chamber…
