The oil mist-containing atmosphere is taken in via the intake funnel and, at the same
time, splash oil is prevented from getting into the header pipes by an integrated labyrinth
geometry. Precipitated oil can permanently block the header pipes and ultimately
prevent the test medium from being taken in continuously.
The fitting body allows for angular adjustment to accommodate the intake lines and
forms the connection between the header pipes, intake lines and the crankcase.
Schaller Automation offers engine wall connections in various versions and specifically
to match the engine geometry.
4.3.6 Siphon block
The siphon block is the alternative in the installation kit to the engine wall connection
(EWC). If necessary, this is used instead of the engine wall connection (EWC) (Fig. 11, 3)
if the standard drainage concept using the pipe siphon (Fig. 10, 4) cannot be used for
reasons associated with the application.

4.3.7 Hose lines
As an alternative to the rigid intake and exhaust air lines, flexible hose lines can also be
used, as shown in the figure below. The core of these lines consists of a hydraulic hose,
with an additional sheath of galvanised wire mesh.
