This uses motor exhaust as an inert gas to reduce the risk of explosion in the balloon envelope, specifically "the space between the outer cover and the balloon cover proper."
It looks similar to Patent DE-1908-220975, though not identical; the latter does describe a use of engine gas, but without the application as a protective layer in the balloon envelope. The British patent does make reference to the German priority date 1908-08-14, which is fitting.
