Crank case ventilation system`s oil ejection determining method for automobile, involves guiding ventilation gas by filter, holding weight difference of filter for determining quantity of oil ejection, and heating gas lines or housing

摘要

The method involves guiding ventilation gas by a filter. The filter is undulated before and after its gauge slide, and the weight difference of the filter is held for determining quantity of oil ejection of a crank case ventilation system of an internal-combustion engine. Ventilation gas lines (6-11) and a filter housing of a measuring arrangement (4) are heated for more than 100 degrees Centigrade. The ventilation gas is guided through a separator provided in a crude oil sink (16) before the gas is led through the filter. An independent claim is also included for an arrangement executing a method for determining oil ejection of a crank case ventilation system of an internal-combustion engine with a filter.
