Spark plug rinsing arrangement for piston combustion engine, has pressure chamber exhibiting preset volume, and pressure chamber nozzle exhibiting predefined shape such that pressure chamber airflow reaches flammability region of spark plug

摘要

The arrangement has an axially-concentric pressure chamber (10) connected with a combustion chamber (5) over a pressure chamber nozzle (11). The pressure chamber exhibits preset volume, and the pressure chamber nozzle has a predefined shape such that pressure chamber airflow (7) reaches a flammability region of the spark plug during each engine stroke and the fuel particles and/or the air/fuel mixture of a fuel jet (8) are blown out into the flammability region, where the intensity of the pressure chamber airflow is preset such that the ignition spark of the spark plug is not blown out.
