THE INFLUENCE OF IMPROVED ELECTRICAL IGNITION UPON COMBUSTION IN SPARK-IGNITION CARBURETTOR-TYPE ENGINES

DIE AUSWIRKANG EINER VERBESSERTEN ELEKTRISCHEN ENTFLAMMUNG AUF DIE VERBRENNUNG IM OTTOMOTOR

Test-rig results have shown that in actual engines ignition is most influenced by the discharge phase of the spark ignition. Specially designed tests with different types of ignition systems demonstrated that, independently of the fuel-air ratio lambda, the reliability of ignition could be increased and the speed of combustion could be increased. Over a narrow range there were significant improvements in fuel consumption and efficiency as compared with tsz ignition (electrode gap 1.2 mm), as well as lower nox emissions for a given power output. The trends which have been demonstrated justify expectations that, simply by increasing the energy released in the discharge phase of the spark, a way can be opened up to new concepts of economy.
