Lanova injection process

from Wikipedia, the free encyclopedia

The Lanova injection process is a forerunner of the direct injection process known today . It is based on the Lanova air storage process for diesel engines and was patented by Franz Lang .

technology

The engine design connects the external accumulator in the cylinder head with a special shape of the combustion chamber . The butterfly-shaped combustion chamber - seen from above - led to a particularly favorable turbulence when blowing out the air reservoir. As a result, the engine still worked soot-free even with a small excess of air - which corresponds to a high load. The fuel consumption is slightly higher than with the direct injection engine, but lower than with the pre-chamber engine .

The last version of the Lanova process was not prone to faults and made relatively few demands on the injection system . The fuel consumption was low, the smoothness was remarkable. The Henschel company in Kassel used the Lanova process, as did a number of other licensees . In this context it should be noted that before the Second World War even the development of an aviation diesel engine was carried out with the Lanova process (designed as a nine-cylinder radial engine ); this BMW 114 project , however, was not completed and discontinued in 1937.
