Description
この場合、交差部分という狭い領域でしかプラズマを発生させることができないため、排ガスの浄化効率が低いという問題がある。また、特許文献3に記載の従来技術では、同一パターンの貫通孔が設けられた電極を並列に配置したものであるため、放電の起点となる部位が、上側の電極に設けられた貫通孔の開口縁と、その直下にある貫通孔の開口縁とに限られてしまう。よって、この場合も、狭い領域(開口縁付近)でしかプラズマを発生させることができないため、排ガスの浄化効率が低いという問題がある。さらに、特許文献2に記載の従来技術では、一方の単位電極にしか貫通孔が設けられていないため、放電の起点となる部位が不特定となる。この場合、プラズマの発生範囲や発生量が変動しやすいため、排ガスの浄化効率が低いという問題がある。
