Description
例えば、水の電気分解によって水素ガスを生成している場合には電気分解の電流値を制御し、また水素ガスをボンベに貯蔵している場合には、流量調整弁の開度を制御する。
水素ガス混合燃料の省エネルギー効果を確認するため、試験設備を実験船(源吉丸)に搭載し、実航海を行った。詳細は以下の通り。
・三重県志摩市和具町 御座岬沖 海域
・実航海実験の内容:浜島沖海域において、ほぼ260度の方位線上に2海里離れた標識を設定し、この間を以下のエンジン回転数2条件、ガス供給量(水素ガスの混合量)3条件の6ケースについて、各1往復し、燃料消費の変化を調べた。
(1)
エンジン回転数:450rpm
ガス供給量:無し、4000cc/min、5000cc/min、
(2)
エンジン回転数:550rpm
ガス発生量:無し、6000cc/min、7000cc/min、
・実験船名:第八大恵丸
・実験日時:平成27年2月28日〜3月2日
・山口県長門市青海島沖海上
実験結果は以下の(表2)及び(表3)に示す。
実験例3は自動車(トラック)について、水素ガス混合燃料の省エネルギー効果を確認するために行った。
車両:日産ディーゼル パッカー車ベースレッカー車
エンジン排気量:4,570cc
車両重量:4,285kg
走行距離数:86,895km
使用燃料:軽油
ボッシュタイプ噴射装置
水素ガスを添加しない場合の実験結果は以下の(表4)に、水素ガスを添加した場合の実験結果は以下の(表5)に示す。
4月28日の高速重視走行では、燃費結果よりも走り重視で、加速感、最高速度などを目的としたこと、首都高の断続的な渋滞も重なり、7.83%の燃費向上となるも、登り坂での反能力もスピードダウンもなく他車両を追い越せる等トルクアップしていると思われた。
9A(835cc)ガス添加では、4速アイドリングでの走行もノッキングすることなく走行することができた。13A(1223cc)ガス添加では、確実にエンジン音が軽くなりレスポンスも非常に良くなった。
Claims (2)
- 液体燃料またはこれにガス燃料、固体燃料を混合した液体燃料に空気を供給して燃焼させるエネルギー発生装置の燃料燃焼方法において、前記空気中に前記液体燃料よりも火炎伝搬速度が速いガスとして水素ガスを添加し、この水素ガスの添加量を燃料を完全燃焼させるのに必要な空気量に対して体積比で0.01%以上0.1%以下の割合とし、当該水素ガスの燃焼によって燃料と空気との混合を助長し、前記液体燃料を構成する分子をより分子量の小さな分子に分解して燃焼させることを特徴とする液体燃料の燃焼方法。
- 請求項1に記載の液体燃料の燃焼方法において、燃焼装置の出力増減操作に応じて、前記火炎伝搬速度が速いガスの添加量を変化させることを特徴とする液体燃料の燃焼方法。
