Description
Claims (10)
- 燃料を内燃機関に噴射するための方法であって、燃料にまず最初にガス添加装置(20)でガスまたはガス混合物、特に酸素または空気を添加し、この場合、燃料を噴霧し、この噴霧された燃料にガス・ガス混合物を供給し、次いで、ガスが添加された燃料を直接に少なくとも1つのシリンダ(12)に、または間接的にその手前の領域(17)、特にエンジンの吸気管に最終的な噴霧の経路において噴射する方法において、
燃料を少なくともガス添加状態で、最終的な噴霧まで冷却し、これによりガス・ガス混合物が最終的な噴霧の前に燃料から流出するのを防止することを特徴とする、燃料を内燃機関に噴射するための方法。 - ガス添加燃料の温度を、最終的な噴霧の際に1〜10℃、有利には1〜3℃にする、請求項1記載の方法。
- ガス添加燃料の温度をガス添加装置によって最終的な噴霧まで1〜10℃、有利には1〜3℃にする、請求項1記載の方法。
- 燃料に添加する際のガス・ガス混合物のガス圧を、最終的な噴霧過程の際のシリンダもしくはその手前の領域における空気圧よりも高くする、請求項1記載の方法。
- 前記ガス圧を、最終的な噴射過程の際のシリンダもしくはその手前の領域における空気圧よりも1.2〜50倍高くする、請求項4記載の方法。
- 少なくとも請求項1記載の方法を実行するための内燃機関のための噴射装置であって、燃料にガスまたはガス混合物、特に空気を添加するためのガス添加装置が設けられており、該ガス添加装置が、燃料にガスまたはガス混合物、特に酸素または空気を添加するための添加室(20)を有しており、少なくとも1つの噴霧手段(21)と、添加室にガスを導入するための少なくとも1つの開口とが設けられており、添加室に燃料を供給し、かつガスまたはガス混合物を供給するための少なくとも1つのポンプ手段が設けられており、ガスが添加された燃料を添加室(20)から最終噴霧手段(18)へと案内するための供給導管(30)が設けられており、前記最終噴霧手段(18)は、ひき続きガス添加燃料をシリンダ(12)に直接的にまたはその手前の領域、特に吸気管(17)に間接的に噴射するために設けられている形式のものにおいて、
冷却システム(33)が設けられており、これにより少なくともガスが添加された燃料を、最終噴霧手段(18)における最終的な噴霧まで冷却し、これによりガス・ガス混合物が最終的な噴霧前に燃料から流出してしまうのを防止することを特徴とする、少なくとも請求項1記載の方法を実行するための内燃機関のための噴射装置。 - 冷却システム(33)が、少なくとも添加室(20)を、有利には供給導管(30)も冷却するように形成されている、請求項6記載の噴射装置。
- 添加室(20)が、特に閉じられた室(20)であって、該室(20)が、ガスまたはガス混合物を導入可能な少なくとも1つの入口、特に流入弁と、燃料を室(20)に噴射可能な、特に噴霧可能な有利には少なくとも1つのノズル(21)とを有している、請求項6記載の噴射装置。
- ポンプ手段(23)と圧力制御手段(26)とが設けられており、ガス・ガス混合物及び/又は燃料が、制御された圧力下で室(20)に導入可能であって、これにより室における圧力を制御された圧力下に維持することができる、請求項8記載の噴射装置。
- 前記室におけるガス添加燃料の量を測定する充填レベルセンサ(32)が設けられている、請求項8記載の噴射装置。
