Title:
気体燃料噴射内燃機関およびその運転方法
Document Type and Number:
Japanese Patent JP4441620
Kind Code:
B2
Abstract:
In an internal combustion engine an ignition device (30) is disposed within the combustion chamber (13) in close proximity to a fuel injection nozzle (20). The ignition device (30) comprises a sleeve (34) that provides a shielded space (33) around a hot surface igniter (32). The sleeve (34) restricts flow between the shielded space (33) and the combustion chamber (13). The nozzle (20) comprises a fuel injection port that is oriented to direct at least one fuel spray (22) onto the sleeve surface (34). The sleeve (34) comprises an intake opening through which air and fuel enter the shielded space to form a combustible mixture therein. The hot surface igniter (32) comprises a tip located close to the centerline of the intake opening (36). The combustible mixture is ignited within the shielded space (33) and a combustion flame is propelled through a discharge opening and into contact with fuel sprays emerging from the fuel injection nozzle (20). Methods of operating such an engine are also disclosed.
