Improvement of the Cold Start Qualities of Diesel Engines with Swirl Chambers 940075

A spark ignition was adapted to a passenger-car- type Diesel engine with swirl chambers. This should improve the cold start qualities, which are sometimes insufficient because of the long ignition delays.
Now there were no problems with the cold start. The engine start happened rapidly and the engine run was very smooth. Other advantages could be found, too. E. g. the HC-emissions of the warm engine start could be decreased significantly. The energy consumption was only 10 % of the standard glow plugs and it is possible to decrease the compression ratio of the engine.
