Abstract
Description
可視蒸気および気体状副生成物が注入される流体系は、自動車の流体系であってもよい。前記自動車の流体系は、エアブレーキ系であってもよい。
検出するステップは、気体検知器の使用を含んでいてもよい。気体検知器は、低感度モードと高感度モードとを有し、検出するステップは、低感度モードと高感度モードとの間で感度モードを切り替えることを含んでいてもよい。
別の態様は、可視蒸気および気体状副生成物を発生させるために発煙剤を加熱することが可能であり、かつ、可視蒸気および気体状副生成物を流体系に注入することが可能である発煙器を備えている漏れ検出システムを提供する。このシステムは、発煙器で発生させた気体状副生成物を検出するように構成された気体検知器をさらに含む。
前記発煙器は、可視蒸気および水素を発生させるために、白色鉱油またはポリアルキレングリコール油を加熱することが可能であってもよい。
本明細書で発明する種々の態様のこれらおよび他の特徴ならびに効果は、以下の説明および図面との関連で、より良く理解されるであろう。
添付の図面に関連して以下で記載する詳細な説明は、漏れ検出システムおよび関連する方法のいくつかの実施形態について説明するものであって、考案または使用され得る唯一の形態を表すものではない。説明では、図示の実施形態に関連して、各種構造または機能の少なくともいずれか一方について記載しているが、理解されるべきことは、同一または同等の構造や機能を様々に異なる実施形態によって実現し得るということであり、かかる同等品もまた本発明の範囲内に含まれるものとする。また、理解されるように、「第1の」「第2の」などのように関係性を示す用語は、一の実体(entity)を他の実体から区別するためにのみ用いられており、各実体相互において、当該用語の意味する実際の関係性、あるいは順序を必ずしも必要としたり、示唆したりするものではない。
